Each file type is in a different format.  The formats are different
essentially for two reasons:

1. the files contain any other type of information. For
example, an mp3 file contains a music and a xls file contains a
worksheet. The music and spreadsheets are very different things and one
a unique type of guy would not work for both.

2. There is also the example of the types of files that are very different, even
Although basically they both contain the same type of data. For example,.
a doc file is a file created by Microsoft Word processor (or
some compatible programs) and a wpd file is a text file
created by WordPerfect. This is because Word and WordPerfect are two
very different programs, with very different characteristics. Designers
and authors of each of the programs designed for a type of file that would be
works very well with their program.

  • PDF stupid question: what is the difference between 'Save as PDF' and printing to PDF "printer"?

    Is there a difference in quality?

    The "save under" seems to distill, but if I select 'Print Document' and select 'Adobe PDF' as the printer, it also seems to work OK, although I sometimes get a "Times" font unavailable, will be replaced by "Times New Roman", although I can't find any reference to "the times" in my book.

    Is there an advantage to running distilled?

    Thank you!

    They are essentially the same - one is traditionally more stable (print) than the other (save as).

    Your mystery police can hide in a graphic somewhere sometimes a review of MIFID can show it. You can always try the substitution of suggested police and save the file 'fixed' If you don't care time.

  • What is the difference between nivisa4.lib and visa64.lib

    In

    C:\Program Files\IVI Foundation\VISA\Win64\Lib_x64\msc

    There are 3 lib files: nivisa64.lib, visa64.lib, visa32.lib

    And in C:\Windows\System32 are the 3 corresponding .dll files.

    I understand that I link to visa64/visa32 depending on whether it is a 64-bit or 32-bit computer.

    But what is nivisa64.dll and nivisa64.lib good for? I need for communication with my camera? What is the difference between visa and nivisa?

    Hello

    There are currently 4 import libraries.

    3 are provided by visa32.lib of NI-VISA (one in a folder of British Colombia and the other in msc) and nivisa64.lib. The other lib visa64.lib is provided by the shared components of VISA.

    So the difference between the nivisa64.lib and the visa64.lib is the author of the file.

    nivisa64.lib National instruments and the visa64.lib is provided by the shared components of VISA.

    I hope this helps to clear up the confusion.

  • Creative Cloud Files vs. Document Cloud Files - what is the difference between them?

    Hi guys, good afternoon everyone.

    Here I was wondering what is the difference between creative Document Cloud Files and Cloud Files?

    I'm new here and couldn't find an answer.

    Screen Shot 2016-09-13 at 6.15.03 pm.png

    If someone could help me, that would be very appreciated

    Kind regards

    Creative Cloud files are stored in your CC account synchronized.

    Document Cloud files are the only pdfs stored with the sync Acrobat DC system.

    The two are separate storage options. However, the DC option synchronizes perfectly with all your versions of Acrobat (mobile, desktop, etc.)

  • What is the difference between the file index and swap file

    What is the difference between the .pag and .ind files?

    I know that the file contains data real means-data blocks and cells and the index file contains the pointer to the block of data that is available in the paging file.

    but is there another difference? What about size?

    In my opinion, pagefile size is always greater than the index file. It is Scripture?
    If the size of the Index file is larger than the pagefile so that it happened? If the size of the index file is larger that the pagefile is then write?


    If I deleted the page file, then it is assigned to the index file?
    or
    If I deleted some data block of the pagefile, then how is affects the index file?

    Published by: 949936 on August 27, 2012 06:32

    Are these test questions? Well, in the hope that in fact 949936 instead has a strong sense of the investigation, here goes:

    In my opinion, pagefile size is always greater than the index file. It is Scripture?
    If the size of the Index file is larger than the pagefile so that it happened? If the size of the index file is larger that the pagefile is then write?

    ^ ^ ^ Generally the. IND index, or the files are smaller than the. PAG page file (s). However, there is a minimum eight megabytes index file size. If clearly on a BSO your database and send a single number (which equals one block), you will have a. IND, quite a bit larger than the. PAG.

    For example, I have cleared out the good old Sample.Basic and then sent the number "5" in the "New York"-> "Cola"-> "sales"-> "Jan"-> "real." This resulted in a. The IND of 8 216 576 bytes, and a file size. PAG 149 bytes file size.

    If I deleted the page file, then it is assigned to the index file?

    ^ ^ ^ Are you sure this isn't some kind of certification exam? Do you mean that you went down to the BONE and deleted the file? Irretrievably corrupted, the database is what will happen. If you want to clear data, I guess it depends on how you do it. Send to a #Missing 5 has increased the size of the. PAG 149 to 229 bytes file. My guess is that doing so forced the overhead on Essbase. There is no impact on the. File of the IND in this context.

    If I deleted some data block of the pagefile, then how is affects the index file?

    ^ ^ ^ If you delete data into Essbase (whether through the above method which clears completely a block or CLEARDATA command) and then force a restructuring by MaxL or EAS, if the number of blocks have been reduced enough to cross this limit of eight megabytes, you should see the. IND file size down. I see usually do this all the time with backup processes every night that have a component of restructuring for them.

    I hope that answers your questions. You can watch the SER60 that there is a fairly comprehensive review of storage BSO which are.

  • What is the difference between the file httpd.pid and httpd.lock?

    What is the difference between the file httpd.pid and httpd.lock?

    Salvation;

    Apache httpd saves the id of the httpd process parent in the file logs/httpd. PID.

    LockFile

    Sets the path to the lock file used when Oracle HTTP Server is compiled with USE_FCNTL_SERIALIZED_ACCEPT or USE_FLOCK_SERIALIZED_ACCEPT. It is recommended that the default value be used. The main reason for changing it is if the logs directory is NFS mounted, since the lock file must be stored on a local disk.

    "For example: LockFile /oracle/Apache/Apache/logs/httpd.lock.

  • What is the difference between the cat of the IR and IR data files in lightroom it please

    I have cat IR and IR data files in my backup. These two are big files of 500 MB, 900 MB respectively. My understanding is that these records did not contain real images but only thumbnails with the mods of lightroom. What is the difference between the cat of the IR and IR data files and should I make a second copy of both or the cat IR file

    The.lrcat is the file in your catalog. This is an important safeguard.

    The .lrdata files have previews. These can always be regenerated from the library, but it could take some time a large catalog.

    It is advisable to save them both. But if you are short on disk space, save the .lrcat file.

  • What is the difference between Pro Acrobat and LiveCycle Designer 8.1ES?

    Hello

    What is the difference between Pro Acrobat and LiveCycle Designer 8.1ES?

    Thank you

    Hello

    They are two different programs.

    Acrobat

    This can be used to generate other types of document native PDF files. In addition, you can create forms that are called AcroForms. These retain most of the functionality that looks like in Acrobat to comment on.

    The form IS a PDF file.

    Acrobat is avialable for Windows and Mac.

    LiveCycle Designer

    This program is used to develop forms and is completely separate from Acrobat. The forms are called XFA forms, which means XML Forms Acrhitecture. The focus is quite the processing of data.

    While the forms that are created in the designer of the LC can be opened in Acrobat (Reader), they are not native PDF files and some of the features normally is not available. For example, while you can add data to the fields when the form is opened in Acrobat, you can not change the form itself in Acrobat. If you want to change the form, you will need to open again in LC Designer.

    It comes with the Windows of Acrobat Pro version. There isn't a Mac version of LC Designer.

    It's a broad overview brush, it could be useful.

  • What is the difference between folders: ' all ' and 'Photos' - it's just to start!

    Following a major problem with iPhoto and several telephone conversations with Apple, they have updated my OS to OS X El Capitan 10.11.2 which of course includes Photos.  Considering that it took a few minutes to import, for example, 400 photos from a trip to New Zealand, it now takes 40 minutes to import and sort then maybe a dozen. I seem to end up with copies in records last import, all pictures and Photos.  Also following the upgrade, all my previously deleted photos "reappear" so I got over 18 000 instead of the expected 12-13, 00.  It took hours to sort - and still sorting...

    First question: what is the difference between all the Photos (posted at random), Photos (posted by year/day)?

    Second: Photos sitting in the last import files - where do they go once they have been placed in my Albums?

    1. they are not records - photos exactly as the iPhoto files hold not photos - they have other folders or albums

    2 - both are standard SystemTop - photo albums, photo exhibition which is not hidden in a sort of photo date (years/collections/moments) and all photos shows all pictures sorted by date of adding Photos

    3 - the last import also isn't a folder - it's a special album that shows the latest photos imported - they will not anywhere – when you import again the importation of latest news is shown

    4. don't 'put' Photos in albums and they don't go anywhere that you never move anything in Photos (or iPhoto) - all photos are still in the library and view you through different methods, including albums (used for the Organization), all pictures, Photos and possibly other SystemTop albums

  • What is the difference between Windows 7.x86chk.symbol.msi and Windows 7.x86fre.symbol.msi?

    What is the difference between windows 7. x86chk.symbol.msi and windows 7. x86FRE.symbol.msi

    Hello

    Thank you for contacting Microsoft Community.
    If my assumption is correct, you are looking for which file to download service pack update.
    Worry not choose files. Download the .iso to the update file, either burn it or mount or extract it and install. These files are called the symbol files. They differ in the language, for example. frequency refers to the French version. They are used to debug the Service Pack and are not really necessary unless you start to run into problems and try to find solutions on your own.
  • Portfolios - what is the difference between the password, certificate of security and management of the lifecycle of the rights Adobe?

    I would like to use Acrobat DC Pro to create secure portfolios. These will be used to store payable files that should not be considered by most employees. What is the difference between the password, certificate of security and management of the lifecycle of the rights Adobe?

    Password encryption methods, certificate of security and Adobe lifecycle management of the rights for the portfolios are the same as for a single PDF file. If you are a novice to the encryption Acrobat Adobe Acrobat X Pro * choosing a method of security will help. You can have the portfolio itself unencrypted and encrypt some or all files with whatever method you choose, or encrypt the portfolio himself and, still encrypt or not encrypt files that you place in the portfolio. Each encrypted file can use the same or different encryption with the same or different credentials method. You can encrypt portfolio encrypt attachments only. In this case the portfolio itself is not encrypted, but all the files in the portfolio are encrypted with the same method/diploma. When a user opens this portfolio list of files appears. When the user clicks on a file in the list Acrobat checks credentials (in the case of password security, he asks the password) before opening the file.

  • What is the difference between readResourceContent and services ReadDocument...

    What is the difference between readResourceContent and services ReadDocument...

    Why if I create the file or folder write document\ create the directory, then it is not visible from the work bench...

    If I create the file using WriteDocument... It shows the created path

    / Apps/KI01/AF-was61-PP01/AppServer/Profiles/AF-node61-pp

    01-01/uploadfiles/test.PDF

    It is what... tell me differences...

    ReadResourceContent is used to read the documents in the repository of LiveCycle (the database LiveCycle).  ReadDocument is for reading binary files to the file system of the server (hard drive).

    If you create a file with write document\ create a directory it goes on the servers file system - its disk hard - and not in the repository of LiveCycle (the database).  Indeed, the repository may be hosted on a different server (in the case of a remote database).  If you write a file "/ apps/ki01/af-was61-pp01/AppServer/profiles/af-node61-pp01-01/uploadfiles/Test.pdf", then check the hard drive of the server, then you will see the files are there. If it is a control of the C: drive for this file Windows box.
