How reliable is zipping in Windows 7 Explorer?

    Question

  • There have been times in the past when a zip file I created was corrupt (or became corrupt somehow).  I encountered this either using WinZip or command-line zip, possibly in old Unix environments.  To me, there is a risk in relying solely on zip archives and deleting the original unzipped files.  The risk isn't only in losing one file that is corrupt -- any corruption anywhere in the entire archive could render all the files therein inaccessible.  Hence, the risk increases with the size of the archive.

    How reliable is the zip that is native to Windows 7?  In addition to that general question, what about specifically for files in the Gigabyte range (fraction of a GB or several GBs)?  If it is very reliable, then I will use the Windows 7's "compressed (zipped) folder" to create archives for writing to DVD.

    I am using Windows 7 Professional 64-bit.  I want to avoid discussion about Windows 7 backup as it is not suitable for my specific purposes.

  • Hi,

    In my opinion, I think the build in zip for Windows 7 is very reliable. It can be work normally even the file size is large.

    If you are worry about the zip file would be corrupt, you can backup all the files before compress.

    Regards.
