HandZipper 1.1.2 Review
By Edward Green
Zip files are one of the most common methods of desktop file compression and most downloaded Palm software comes ready zipped to reduce download time. HandZipper offers limited compression and decompression of Zip files on VFS-enabled Palm handheld.
This size reduction was born out in tests; 5.2 MB of files on my Clié were archived into a 2.8 MB Zip file. This Zipping operation did take several minutes however, and cannot be interrupted.
Only files in device memory can be archived; files on your memory card are unavailable.
Here, however, is HandZipper's main limitation; Files can only be unzipped to the handheld's main memory, they can't be unzipped onto the memory card. HandZipper recognizes files which aren't standard Palm file types and, although it tells you they are there, it doesn't let you do anything with them.
Adding Zip files to your memory card is straightforward; On your PC simply drag the file into the Palm install tool and it will install onto your memory card at HotSync. Software can be downloaded in Zip format, copied onto a memory card and then unzipped and installed into device memory, although the unzip operation can take some time.
Uses & Limitations
A second possible use is for the maximization of memory card space. Infrequently used software or files can be zipped to almost half their original size and stored on the memory card. For applications that use large files such as Acrobat or Teal Movie this is a definite advantage. However, HandZipper also disappoints in this area because it can only unzip into device memory, limiting the user to a file no larger than free RAM.
It is also worth mentioning here that some Palm Applications create filenames that are illegal on desktop machines, PowerRun for example uses "**", which cannot be unzipped under windows.
