File and Folder Compression in Windows 7

Are you running short of disk drive space?  Given the size of video and picture files it is easy to run out of hard disk drive space. Well, there’s a simple answer for you! Compress important files to save disk valuable hard disk space.

Why Use File and Folder Compression?

  • A Compressed file or folder takes up less storage space.
  • Besides compressing files you can create a compressed folder and store several files inside it.
  • You can copy or move a compressed file or compressed folder to another drive or computer quicker than conventional uncompressed files or folders.
  • You can work with compressed files and folders in the same way as you do with uncompressed files and folders.
  • Files and folders are easier to share.
  • You can compress all types of files – picture files, video files, music files and document files to name just a few.

If you choose the compressing files option there are two ways you can do it. The first method involves creating a blank compressed folder.

The Document Library will be used for this demonstration.

  1. Open the Documents Library.
  2. Right click on a blank area.
  3. A pop-up menu appears.
  4. Select New.
  5. In the menu, click Compressed (zipped) folder.pic 1

    Another reason to use compressed folder is to keep the files date/time intact when you transfer them on ftp or email. If you transfer a file the date/time is refreshed with the local computer date when it is download.
    In our company we need to know the last modification date/time for each program file.

        Sorry I meant no offence, it’s a very nicely done guide that must of taken considerable time, but its like making a two page guide on how to use the start menu lol.

          No offence taken. The blog sure took a long time but Snagit makes it easier. I always write stuff for the beginners so tend to tell it all.

    I guess it’s good to know how to do this, but I just use 7-Zip. It’s a lot faster and has more features.

    Personally, I prefer to use WinRAR as it can open “zip” file extensions.
    Btw, these guides are excellent for beginners and the screenshots are very helpful. Great effort :)

    Is there a control or method for setting the compression ratio for Wind-7?

  7. Guest May 12, 2011 at 12:47 pm #

    I have somehow lost the ability to access and use the zip function that comes with Windows 7. Does anyone know how I can get it back?

    I think the version of compression in Windows 7 is incredibly slow.  It doesn’t provide any choices for naming at the time of compression (better than the several steps shown in the guide) and doesn’t allow you to direct the compressed file to another folder.  Also, if there happens to be any apostrophes or emplty files, it fails and creates nothing.  Don’t like it at all.
