Maximum space on a file compressed in Windows 7.

I have created a compressed folder (.zip) and added 3 videos.  2 videos are 4 GB, 1 video 2 gig which is around the 10-11 concert in the compressed folder.  My question what is the maximum size of a compressed file?

Although the initial version of only zip file specification allowed up to 4 GB (the implementation in XP was apparently limited to 2 GB - LINK), you have a version of the algorithm that (probably *) allows up to approximately 16 billion gigabytes.

However, the problem you have is that video files are usually already compressed, and attempt to use zip or similar of lossless compression algorithms to compress them often lead to a larger than the original file.

You can compress video files by converting to a different format, but generally, this will result in the loss of detail.  See, for example, http://www.wikihow.com/Compress-Video

___________

* ' probably' because there are different threads, which suggests that the Microsoft implementation may have a lower limit, even for Windows 7 and later versions.  I have, however, seen a report of a Zipper successful a file of 20 GB on Windows Server 2008 R2, which was built on the same core as Windows 7.  Which suggests that Windows 7 should be able to manage a file at least that large.

  • clean files compressed into disk

    I just did a disk cleanup and I have 1 273 986 kb of compressed files.  I'm afraid to delete and can't find them on my PC anywhere if I can see what files are.  Can anyone help?

    Thank you... Dick

    Thank you for your response.  You say that it's OK to delete old files compressed during the disk cleanup?  If I delete these files, how can I know what I'm deleting?  Where are they available for consultation on my C drive.  I don't want to delete a file that I regret deletion.  I did a disk cleanup, but I chose not the old files compressed to the deletion for this reason.

    Do not delete the 'old files compressed."  The system may well have compressed the files you want to keep.

    By default, the XP Disk Cleanup tool offers "compression of old files."  If you use this option, the system compresses the files that have not been used for some specified time (I don't know the value).  The files remain on the hard drive - exactly in the same place, they were--and if you access a compressed file, the system he unzips on the fly.

    If you have not changed the default settings of the system, when you open Windows Explorer, the already compressed files this way are shown in blue (a green file is encrypted).

    For a view of the compression of the files (which I share), see the user 'A' answer in this thread: http://answers.microsoft.com/en-us/windows/forum/windows_vista-performance/disk-cleanup-compress-old-files/8ffe74e5-23c8-4787-ad91-0cc329bd2c0a
    In addition to some risk, there may be in file compression, it often takes a long time for disk cleanup to "[e] er how much space you will be able to release" by compressing the files.  For this reason, some people (including me) turn off this feature of disk cleanup: http://support.microsoft.com/kb/812248

    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.

    You can disable hibernation if it is enabled and you do not...

    When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

    -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
    -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
    -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

    You can control the amount of space your system restore can use...

    1. Click Start, right click my computer and then click Properties.
    2. click on the System Restore tab.
    3. highlight one of your readers (or C: If you only) and click on the button "settings".
    4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
    5. click on OK. Then click OK again.

    You can control the amount of space used may or may not temporary Internet files...

    Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

    -Open a copy of Microsoft Internet Explorer.
    -Select TOOLS - Internet Options.
    -On the general tab in the section 'Temporary Internet files', follow these steps:
    -Click on 'Delete the Cookies' (click OK)
    -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
    -Click OK.
    -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).

    Compress, (Compact in American English), removes waste of space, not your messages. Please read below, but if compact you and still get the prompt, after return. It is another question.

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

    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.
