Problem of compressing files

Hi all

I'm having a problem of compression of strange file with CS5 on our new Mac Pro.  We bought the Mac Pro to scan and process the images, but the JPEG and GIF files we create from this computer is much more important that they should be closed (for example images that should be compressed to 6 KB read 60 KB and the size of the file is often smaller when open to closed). In addition, every time we use these image files in other programs (e.g., Filemaker Pro) the inflated file size will be.  What is even more amazing, is that the same files that read like 60KO on our Mac Pro will be correctly read as 6 KB from a PC.  Similarly, if we incorporate these images - which were created on the Mac Pro - in Filemaker from a PC, the size of the image file is correct.  We cannot use the compressed files, we create on our Mac Pro because the inflated file size will affect any application that we use on the Mac Pro (except Photoshop).

We have been processing images on a PC for years and have not had any problems with this.   We thought for a while that the problem was with the Mac operating system, but after many calls with advisers from Apple, it seems that Photoshop for Mac has the issue.  We have already tried to reformat and re-indexing the hard drive, and at this point, there is nothing else that can be done at the end of Apple.  The expert last I talked to Apple says that this looks like Photoshop for Mac compress files and how Mac reads the files size is very different from the way of Photoshop for PC compress files and how Windows reads the size of the files.  Is it was okay, and there is no work around, we will have no choice and will have to return our Mac.

Everyone knows that before?  Apple experts have been completely confused by the problem and we also.

Thank you
Jenny

This has nothing to do with compression.

Macintosh records more metadata and previews more than Windows - it is a part.

Macintosh displays the size of the file on the disk, including the space wasted due to the size of the disk block - that belongs to another. (Look at the number of bytes, not the size in KB or MB).

When you upload files to a server, or use them in most programs, this additional metadata is lost and the size of the files must be identical.

I can't believe that your advisers spent time on an issue as trivial...

  • Satellite A100 - 147 Compression file error with the product recovery disc

    I have Toshiba A100-147, just out of warranty. I tried to recover with a disk, disk unpack to 69% and then I get the message "ERROR READING OF COMPRESSION FILE (1). I have no choice but to click OK in the error message box, and then quit the recovery as she stops running.

    Any help would be extremely welcome.

    Hello

    It looks like a problem with the Toshiba Recovery CD.
    Have you tried to repeat this procedure?

    What of the HARD drive? You format the HARD drive using an original CD of XP MS?
    It s very interesting if a format of HARD drive could allows to perform the installation of the OS since the Toshiba Recovery CD.

    I remember that something like this has happened on my laptop s friend was not able to recover the operating system using the Toshiba CD. Finally, we found that some sectors on the HARD disk has been corrupted. Format drive HARD allowed integer and my friend was able to install the image of Toshiba.
    It's worth a try ;)

    But of course, this error could occur because of the faulty recovery CD.

  • Compressing files with local characters

    Hello community,

    I will compress files with LabVIEW, but the names of files in the zipfiles be annoying especially since I use English characters such as 'a', 'e' etc. If I zip outside labview then the file names are very well, then I guess it's a thing of labview. Can you help me how can I compress these filenames correctly? Remove / change the file names is not an option.

    Thank you!

    The code that I currently use:

    1984 wrote:

    I checked the document briefly before I sent my post. I sent the UseUnicode = True, it makes no difference. anyway I don't think it's really applicable according to the case that the problem lies in the file add to zipfile.vi which is password protected. Access roads entering this VI have filenames with the correct characters.

    There is no easy way to solve this problem. The zlib library and actually really library miniZIP to cover that was used for the ZIP implementation in LabVIEW does nothing on the character encoding. ZIP files traditionally use some codepage BACK system used at the time. The code page of BACK, however, is not the same as the ANSI code page using standard Windows GUI applications. If any special character in LabVIEW is passed to the function ZIP and it interpreted as a different character.

    The simplest solution would be to convert filenames to the OEM code page before passing the ZIP function and conversion back from OEM to ANSI when it receives the file names of the functions. New formats ZIP support also the UTF8 encoding, but which is not supported by the serving ZIP support miniZIP library in LabVIEW.

    I had to deal with these issues in the Toolkit OpenG ZIP library and this is something very sensitive and involved, especially considering that it should run on the platforms more than just Windows. For now, I decided to work around this problem and to focus on obtaining a new version of the library, without trying to deal with some of these issues of character encoding.

    My recommendation is really just avoid these characters special altogother for now.

    And I'm not sure that you would gain a lot by calling a command line utility. Unlike the GUI Windows programs, the command line utility also works with the OEM code page and assume that its parameters are in this code page, so you will need to convert special characters in any case before generating the command line string.

  • How to recover email files lost after compressing files

    I am using windows XP sp3, two days ago, I performed an outlook express file compression process, after only a quick jump

    and asked me to do. Unfortunately, a part of the e-mail files (year 2011) were found missing in the outmail storage box after file compression.

    I think that they were deleted automatically during file compression. Although I found a backup file in the trash, I can't yet recover

    the e-mails lost after recovery.

    For your information: before compressing files - size storage box outmail - abt, 1.2 GB / after compression 827 MB

    MY mailbox: * address email is removed from the privacy *

    It is a common problem with OE because if we let the dbx files grow beyond a few hundred megabytes, they are subject to corruption.  You should do an immediate backup of your messages in the event of further loss.  So, if you have bak files in the trash or in the message store directory, you can try to recover them.

    For references, see points 2, 3, 4 and 6 here: www.oehelp.com/OETips.aspx#2 and import the bak files see here: www.oehelp.com/backup.aspx#imp1 and if you were unable to recover what was lost, then see here: www.oehelp.com/DBXpress/ the latter is able to scan the entire drive for messages and bypassing the file system and if something can get back them It can.

  • How can I stop OE 'compress files to free disk space,'

    How can I prevent the notice OE ("compression of files to free up disk space"), constantly arise. I moved the cd, deleted files, shortcuts to files, etc., and I still get this pop up to compress files.  very annoying.   Help

    Have let you compact? Disk space is not recovered until you do. Let compact, you should not see the prompt again for 100 closures of OE. If you see more often, after the return. If not, read this.

    *******************

    Why OE insists on compacting folders when I close it? :
    http://www.insideoe.com/FAQs/why.htm#compact

    About file Corruption:
    http://www.Microsoft.com/Windows/IE/community/columns/filecorruption.mspx

    Compacting your folders periodically is a must to keep OE works fine and at some point, you may lose all your saved messages if you do not. When you delete or move messages, the space they used remains until you compact.

    Never touch anything until the compression is finished.* *.

    See:
    www.oehelp.com/OETips.aspx#2

    With SP2, Automatic compaction in the background has been removed because of problems he has caused. Now, you will get a prompt to compact after 100 closures of OE, you need to do, and do not touch anything until it's finished. If you compact manually, at your convenience, this will also set the counter to zero. See this for more information:
    http://www.insideoe.com/files/maintain.htm#compact

    If you are fully patched, you will now see a copy of your dbx files copied to the Recycle Bin as BAK files. If something goes wrong when compacting, the messages can be easily restored from this backup. A compact manual resets also the counter in the back of the registry to zero now.

    For more information, see the information framed in red here:
    www.oehelp.com/OETips.aspx#2

    To keep things running smooth and harden faster:

    Do not archive mail in default OE folders. It will eventually become corrupt and you may lose mail. Create your own folders defined by the user for mail storage and move your mail to them. Empty the deleted items folder regularly. Keep user created folders under 300 MB, and also empty as is possible to default folders.

    And backup often.

  • CRC error on large compressed files (.zip, .rar, .cab, etc...) The installation fails too...

    Hello world

    I have a new Dell computer. It's a Dell Studio 540 with Windows Vista Home Premium 64 bit, with 1 TG of hard drive and 8 GB of RAM. I have problems with "decompression" of a large number of large compressed files (more than 50 GB). Also, because the files on a DVD are often compressed (in the cab for the majority file), the same error occurred on an installation package. Thus, to resume, I got CRC error on compressed files, while opening the zipper AND my different types of software installation fails with errors of Sami.

    Before you answer, please read my steps below:

    1. I reinstalled Windows Vista 2 times from scratch with a clean format. Whenever I get the same error on the same files even when there is nothing installed (even the drivers are not installed).
    2. I tried to run Windows XP Mini, a very light version of XP is the launch of a CD at startup and run in RAM. The same problem.
    3. I did all kinds of tests of the material myself AND with Dell technical support. Nothing was found, and I'm sure it's 99.9% true. Everything has been tested: RAM, hard drive, processor, motherboard, etc. The Dell technical support told me that my computer is 100% functional and that this error is due to some software (Windows) does not very well with 64-bit processor... Everything works well in my work all day EXCEPT for the decompression of data.
    4. my files are not damaged: they unzip perfectly on other computers. In addition, the program that do not install because of the CRC error with compressed file are all used before on another computer OR are new. I even changed DVD to the store to get a new one and the problem is still there. I also tried to download the torrent from the .iso file and the same problem happened.
    5. the files on my computer are not corrupted by the hard drive. I copy keys usb, directrly on the DVD to the hard drive. All possible tests have been done on the files, and they are ok.
    6. I did all kinds of tests such as checkdisk, spyware, etc... but given that the installation has not helped with it, I don't think it's related.

    My last hope is here... MVP is maybe know a problem in which Windows with zip files. I read a lot of people of the CRC errors, so I'm sure something happens. I am currently with the Dell customer service to get a full refund to buy a new computer without a 64-bit processor because it looks too new for Microsoft.

    So if anyone knows something I could try, tweak, change to help me with my problem please let me know.

    Thank you very much!

    Hello!

    This morning, I realized that I never returned to close this topic. In fact, I work with dell for a number of weeks, talk to like 10 or 15 support technical Member, try something else and you know what works?

    Reinstall windows... But in my case, I have reinstalled windows 2 times before they ask me to do it again. So I did and everything worked perfectly... For the third time is lucky: P in fact, perhaps during the first installation of 2, RAM has not been installed properly or has failed for a second, because every file that has been read has become corrupted, but at the same time, everything is normal on my computer seems to work ok... In addition, it could be the update that I did for my BIOS. So, a good test would be to update your BIOS, shut down your computer, check if the ram is installed ok, restart, verify that your ram is detected.

    After that, reinstall your windows, but DO NOT use the file you had on your "not working version of windows. I lost a lot of backup of the thing on my computer because even put on my new fresh install of windows, these rar did not work. I needed to pick up an old DVD and they worked

    So, I hope this will help!

  • How to find my compressed files [ZIP]

    Reference Dell restored my laptop to factory - cannot find the compressed files [ZIP]

    Where records have been saved?

    A restore to factory wipe the hard clean throughout the process. The only option you have is to use a recovery program to recover files deleted from your hard drive. But I doubt if this will help. If the files were very important, then you can give it a try. Search using your favorite search engine to learn more about third-party data recovery programs.

  • Do not open the compressed files

    Hello

    When I compress several files in a zip file and then try to open it, I get the following message:

    (Name) file cannot be opened because there are problems with the content.

    Then I click OK and get the following message:

    Word found unreadable content in (name).  You want to recover the contents of this document?  If you trust the source of this document, click Yes.

    Then, I click Yes and get the following message:

    (Name) file cannot be opened because there are problems with the content.

    I click on details and get the following message:

    Microsoft Office cannot open this file because some parts are missing or invalid.

    I was previously able to open the files zipped without any problem.

    Any help with this issue is appreciated.

    You try to open the file generated with Word.  You must first extract the compressed file, and then open the file with Word.

    Method 1

    Double-click on the zip file.  This will display the contents of the zip file, which are probably more.doc files or Word *.docx files.

    Double click on whatever you want to work on files of words.

    Method 1 has

    Instead of double-clicking on one of the compressed files, drag ' not drop it on your desktop.  It is indeed 'an excerpt' rather than 'extract all' method 2.

    Method 2

    Right-click on the zip file and select "Extract all."  This will create a new folder (with the same name as the zip file).  All the files you have been compressed in the zip file will be in this new folder.  These are copies of compressed files (zipped).

    Double-click on according to files in the new folder that you want to use.

    The problem with all of these methods when you want to save your work.

    For method 1, you must use "save under" (rather than by clicking "Save" or by using the file > save) and don't forget to change the location (folder) where you save the document from the temporary directory that will be the default value to a more appropriate location, such as your desktop.

    For method 1, you can use the regular 'save' function.  The file will be saved whenever you dragged (for example, your desktop computer).

    For method 2, you can use the regular 'Save' function, but be aware that the file will be saved in the new folder created when you extracted all the files.

    In all of the above methods, the version of the file in your original zip file will not be changed.  Assuming that this is not the desired result, after you save the modified file, drag ' not drop it on the zip file.  You will get an offer from the window to "Copy and replace" or "Do not copy."  Choose "copy and replace".  Your modified file will be compressed and placed in the zip file at the original compressed file.

    You can then delete the file updated the registered (method 1 or 1 a) or the entire new folder with all the files extracted (method 2).

    He was never a good idea to compress a drive.

    Some system files and folders don't like it, and if there is a problem with the drive, it will be more difficult to work on the problem. If you have a problem with a compressed drive, after he went on half capacity, it becomes incredibly difficult as the first, must unpack the drive, and if there is not enough space on the disk, decompression does not.

    In my opinion? Do not...
