compression of old files

Hi team - this may seem stupid, but I can't understand... How to compress old files on the computer?  Or when he de-FRAC it itself automatically, the computer is automatically? Thanks - Dave

Disk Cleanup compresses files.

Apart from the removal of unnecessary files, users also have the option of compressing the files that have not been consulted for a period of time. This option provides a systematic compression method. Rarely accessed files are compressed to free up disk space while leaving the frequently used files uncompressed for read/write access faster. If after compressing files, a user wants to access a compressed file, access time can be increased and vary from a system.
Source: http://en.wikipedia.org/wiki/Disk_Cleanup

You can also compress files from Windows Explorer. Right-click on a file or folder and select Properties, general tab, click the Advanced button and check the box before you compress contents to save disk space, click OK and apply and in the next window. You select one of the two options and compressed files poster then in a blue font (default color).  Note you will then see in the properties of the folder or file to a size on the disk as well as size.

Some files compress more than others. There is no point of compression of files regularly accessed.

    I have a question.  By removing the key from registry Compress old files, I erase the disk cleaning ability to compress old files?

    These days, when hard drives are faster and space is less expensive than the good old days, it doesn't make too much sense to compress old files more.

    If you leave the option is enabled and that you have 1 million files on your system, your disk cleanup will take a long time or stuck forever and nobody seems to know just what is the definition of an old file (how old is old?).

    And if XP decided to compress critical system (for example, NTLDR) files, you will not start again in any mode until you uncompress the file (how are you going to do if your system will not start?).

    And if XP compresses these old files and unzip them to use them, that will slow you down even more.

    If you have already removed the key as this article suggests, I would leave it like that and your disk cleanup is going to be zoomine.

  • Under disk cleanup, there is an option to compress old files

    Under disk cleanup, there is an option to compress old files.  Office folklore says that problems come from compressing the files.  Mythology like that change slowly and often does not upward with the reality.  What is the current conventional wisdom on all dangers associated with compressing files?

    Personally, I don't compress files and probably never - if necessary, I'll just get a bigger hard drive (or another hard drive or an external hard drive).  As long as compress you only the correct files (not your files start or something like that), I guess it is quite - safe, but they take longer to open - not much, but some and depends on the size (they need to decompress) practice is always a risk, when something like this as a form of bribery occurs (which is us back to the old mythology (, but the risk is generally considered a minimum and I do not want to exaggerate - but there are).

    Opinions vary among experts and you'll get to the other end of the spectrum.  Some will tell you it is perfectly safe and a good way to save space on your hard drive.  Others take a middle path, and say that they are not positive, but think it's safe, but acknowledge that there are exceptions.  You can see some reactions like the one posted here.  As I said, I personally willnever do (with the exception of some files can I compress for e-mail or because he is great and I expect never to need again, or for other reasons - but they would have been individually selected and completed for a purpose {and using a different program]).  I mean I would never use the option of the files old drive generic cleanup compress to do a little overall with no individual selection (and when I do it with an individual file, it is rare - I probably didn't do so in more than a month - and to be perfectly honest, when I compress a file to send by e-mail I have everything first make a copy and compress the copy and keep the original uncompressed).  I have also seen here situations where people have compressed their files to start with virtually everything else, and this caused them a lot of grief - this isn't an easy repair process and the system does not boot with compressed files (I don't know how they did it-I just saw the messages, but no unread discussions - but if there is no chance that the compression of disk cleanup) been involved (and I'm not, but I did not read how it happened and so I guess it's possible), then it's just another reason for me to stay away).  As you probably now, I don't really have confidence the process (maybe I still have some as old folklore Office in me as I've been around when firstly, he came out and got all these problems) and would rather spend the money on a large or second hard drive what to compress my old files.  I prefer not to take any chance that I don't have in my data which are valuable for me.

    The process is availalble and is generally considered reasonably safe when used properly - but not a lot of experts I know do.  It is MUCH safer than when it came out.  When suggest us ways to save space on the drives for those who have little space and do not want to upgrade or get a new one, it is rare to see someone suggest compression as one of the options (I never do).  We suggest many other alternatives, but I never see this option underlined or specifically suggested (although it may be included as an option in the process we propose you like disk cleanup - and I don't specifically discourage its use is if you heard what I'd say if specifically requested).

    In the end, the decision is yours.

    I hope this helps.

    Good luck!

  • No option to compress old files in disk cleanup

    I have a laptop running Vista and I'm under low disk space so I wanted to compress my old files usinf the disk cleanup option, but when I run Disk Cleanup it has no option to compress my old files.  Can someone shed light on where the option is gone and if I can get it back. Thank you

    You can compress the selected files and folders using this method: http://www.vistax64.com/tutorials/102504-compress-folder-file.html

    Compression of the Windows system files can cause problems. Some file formats are not compressed because they are already compressed. For example, jpg and mp3.

  • "Compress old files" not reset not in Windows XP

    After running Disk Cleanup with "Compress old files" checked, it shows still 79K. I rebooted and represented the disk cleanup, but still the 79K.

    Why the amount has not been reset to 0K?

    What would you choose to compress old files?

    Do you know what he does, how he does, why he does it and what are the consequences?  Most of the people do not - they choose just because it "sounds" like the right thing to do or it "could be" a good idea.

    A popular complaint from users is when they choose that option, their system seems to stop, maybe for hours while XP trying to understand what are the "old files" and what to do about them.  How do you know what is an "old file" and what happens if XP think files are old, but they are not old to you?

    The files more that you have on your system as much time it take and he can just stuck forever and never end up (or you might get tired of waiting).  If you have 1 million files on your system you can wait very long for cleaning disc finish or it can never end.

    And - if Windows find files to compress and that part works, and something you do on your system later needs these compressed files, they have to be unzipped before they can be used.  This will make your system run slower (while you wonder why it is and what to do about this).

    Here are some ideas to consider involving all withdrawal that disk cleanup option - then your disk cleanup will run in a Flash:

    Disk Cleanup runs slowly, the most likely reason seems to interrupt or uses excessive CPU is usually due to the option compress old files.

    Compress old files comes from the good old days, when hard drives were weak and slow, and he had to each byte, you can get on your hard drive for programs and things.  Today, thanks to modern technology, it is almost superfluous.

    Compress old files is supposed to compress the files "have not accessed for a long time" I never found someone who can explain what "were not consulted for a while" means.  What is 'a bit' to XP?  A week, a month, a year, 5 years, is it and how can we change it if you wanted to?

    If you want your clean disc to run faster, I would just remove the option compress old XP disk cleanup files since it is known to crash or give the illusion of being hanged.  If you have 1 million files on your system (or even a few hundred thousand), you wait very long when you run disk cleanup your system may appear to be hung (and maybe it is).

    I really don't think that with the technology available today that compress old files is necessary.  It would also slow down if XP needs unzip a file.  Besides, nobody seems to be able to tell me at what age an old file is in the XP terminology... what was simply a file become old?

    To get the best performance, I just remove this 'feature' and never see him again, and then disk cleanup runs in a Flash because it didn't get old files to compress (some old way).

    That adjustment will reduce considerably this time it will take your disk cleanup to run (I mean a lot).

    It is a 'problem' for some systems that Microsoft has done an article on how to disable it (mine is disabled).

    During a recent drive clean that I discovered I had 21745 KB of old files compressed - what are compressed old files?

    AND is it OK to delete to free up disk space?

    Hi Janie,
    We need a bit more info here. What you saw and where (or how do you here). XP can compress old files when they were little used. These files must be stored somewhere, and I think that you have found where. Do not delete them. If you went on the cleaning disc in the properties of a hard disk, you see where you can disable this active or disabled, but turn it off takes more space because you don't compress these files more. It can take a long time to turn it off too much because the system must find every file, unzip it save it to the hard drive and do the following. If it runs out of disk space free of it, it will stop and make either but then your hard drive will be very close to full and your entire system will slow down (it takes a good amount of HD to 'play'.

    Looks like you need more disk space. Get another drive (expensive) or go to disk cleanup and try to compress the entire drive. It will take a lot of time, maybe hours or overnight depending on the working speed and the player. But it's free. Overnight is best. I think you can stop it (read the help on this). Do not turn It Off during the race. Bad move.

    Something not clear, go back and ask.

  • When running Disk Cleanup, it does not remove anything to "Compress Old Files'.

    When I run my disk cleanup, it does not remove anything to "Compress Old Files' during cleaning.» Why not? I also need more disk space to defragment and I deleted all the programs that I don't use, but is not yet give me enough disk space.

    Compress old files not removes all files, compress files that are rarely or seldom used.

    If you get the low disk space, less than 15-20% free space, then you need to collect as much space as possible. However, the amount you get will not be a solution, only a temporary fix - it that.

    To add or remove programs and Windows components in Control Panel, you can uninstall programs as your plue no use - if you have. Not to be far uninstalling programs, you do not recognize, many elements are required for other programs work properly.

    You can also check to see how much space is reserved for the restoration of the system; by default, many GBs are usually reserved. Also disable hibernation as the file created can be 2-3 GB, sometimes even more.

    You must also consider moving your files and folders on a removable media, such as DVDs or an external hard drive. Still a great flash drive with 4 + GB of space can help, and their prices are reasonable these days.

    In addition to Disk Cleaner, you can consider running CCleaner. This is a free program that will remove the unnecessary and temporary files temporary Internet files of the most popular and many browsers other caches that can be cleaned safely.

    Since you are using Windows XP, there is a setting in CCleaner to remove the uninstallers of patches; These are the Windows Update files you've downloaded and installed over time and are there if you ever want to uninstall the update. But you can save these CD/DVD and then remove them safely from your system to recover the space. If you have ever removed one of these, you may be able to get beyond 1 GB of space.

    CCleaner
     http://www.Piriform.com/CCleaner

    If you decide to try it, by default, that almost everything in Windows Applications and is verified to be cleaned. You must first review the lists (they are compiled by what you have installed) and check/uncheck accordingly.

    Then click on analyze to see what will be removed (nothing is deleted when you click Analyze); When the scan is finished you can double-click on (or right click and select view detailed results) of the entries in the list to get more information.

    According to the detailed results, you can right click for options such as adding to the list of exclusions if you want the deleted item.

    Once that you are completely comfortable with your selections, you can click the run Cleaner button and then OK to put warn before vacuuming will run.

    CCleaner is also a registry cleaner that I don't recommend that you use - even if you have successfully run a registry cleaner in the past, it is quite possible that the next time will bring serious problems; they are not worth the risk...

    I know that this was not the miracle that you can have hoped, but personally recommended solution is a new, larger hard drive. In the case of desktop computers, an additional hard disk is useful for your personal files, especially for music, movies, photos and more.

    I hope this helps.

    Does anyone know the procedure to compress old files (I partitioned my hard drive in drive c and drive d (FAT32)

    If it makes a difference!

    You can use the compressed (zipped) Folders feature offered by Windows XP: read the article at the following web address

    http://support.Microsoft.com/kb/306531/en-us

    If your drive is formatted with the NTFS file system, you can use NTFS file Compression, which is quite different from compressing files with compressed (zipped) folders.

  • Cleaning disc utility compress old files

    When I run the disk cleanup utility, I get 2 729 332 in "Compress old files". I run what it quite frequently and it is still a very large size listed. Is this OK and can only be ignored or are there steps I can take to get rid of old files. I do not know how to find out what old files they reference, so I don't know if I need it or not. Any help would be appreciated. Thank you.

    The disk cleanup utility will prompt to compress files that you have not accessed recently. If you click on this entry and press the Options button, you should see a dialog box where you can set the number of days that must pass before a file compress is compressed. File compression is designed to save space on your hard drive. None of the files in this category will be deleted.

    File compression comes with a cost in performance. If you want to access one of these files must be decompressed before their opening. For this reason, unless you're in a hurry for hard drive space, it's an option you can leave unchecked.

  • Last update does an old file foxfire folder. Can I save it?

    On my desk, there is a folder that says Foxfire old files. What I need to keep or can I delete it?

    The old Firefox data folder is created when you use Refresh. During an update, you sometimes see a message that Firefox is starting or running slowly, and you can speed it up by restoring some default settings. If you click this button, refresh will create this folder.

    More information on what you keep and what you lose a refresh: Refresh Firefox – reset settings and Add-ons.

    If nothing essential is missing then you can remove this folder, but I suggest giving it a few days just in case you need something and you have not noticed yet.
