This small set of files is grouped for your convenience, as all you'll need to cope with most ZIP files on your Psion computer. Copy the UNZIP.IMG and the UNZIP.OPA to the same \APP\ directory and install the icon with Psion-I as usual. Then run and follow all prompts/dialogs etc. Notes: ----------------- 1) ZIP files zipped using the old PKZIP v1.1 format cannot be handled. If you need to unzip something this old, get hold of an older version of the Psion UNZIP utility. 2) Large ZIP files will require LOTS of free memory to extract correctly, you have been warned. 3) For full details on the UNZIP.IMG program, I refer you to the original S3UZIP14.ZIP archive, which contains David Palmer's original release notes and details of all the wierd and wonderful command line switches. This archive should be available from the same place you obtained *this* file.
