Hi,

I need to be able to extract some zip files that I have that are over 4
gigabytes in space. These are important work documents and I need them to
refer back to. I will re zip tem smaller once they have been extracted but
they are coming up corrupted or damaged.

Please HELP!!!

Is this a FAT32 volume? If so you are probably running into FAT32's file
size limit of 4GB when the files get unzipped.

To convert to NTFS, you use the CONVERT command. But first read
http://www.aumha.org/a/ntfscvt.htm because there's an issue regarding
cluster size that isn't obvious.

Also note that conversion is a big step, affecting everything on your drive.
When you take such a big step, no matter how unlikely, it is always possible
that something could go wrong. For that reason, it's prudent to make sure
you have a backup of anything you can't afford to lose before beginning.

I agree that the problem might be that this huge file can't be handled
properly on
a FAT32-formatted drive. Rather than convert your drive to NTFS, maybe you
could borrow a NTFS-formated USB drive for this one little task of
extracting
info. And I'd recommend Zip files be less than 2GB for portability.
