Unfortunately, we don't know a way for the Zoomer to unzip files. This means that most of the files in the Zoomer library can't be used if downloaded directly to the Zoomer. Obviously, we didn't have to be concerned about this until this week when the PDA Forum was opened to Zoomer access. Good problem to have! :)
We have already uploaded some decompressed Zoomer files - to find these new uploads quickly, you can use the PDA Software Search and search on the keyword UNZIPPED.
