the author of this app says:
With CCZip, you can open archives in the popular ZIP-Format that you created on your desktop PC.
You can extract and remove files from the archive, and even create new archives and add files to existing or new archives.
Note, however, that due to the limitations in memory and speed on a Palm PC, CCZip will usually yield somewhat lower (about 20 percent to 30 percent) compression ratios than compression software on a desktop PC.
