Can I use DriveSpace or Compressed drives or disks with Windows XP?
No, Windows XP does no longer support DriveSpace, the disks must be uncompressed first to use with Windows XP. If files need to be compressed, please compress them into zip format with utilities such as Winzip. Windows XP has a built in feature to uncompress Zip files in Explorer. You can compress files or entire folders by opening the properties of the file and folder, select Advanced and then tick Compress contents to save disk space.
