PowerGrasp makes and extracts zip, tar, and gz files

Most modern Symbian phones come with a built-in zip file manager, but what about other data compression formats?

PowerGrasp makes and extracts zip, tar, and gz archives.

The bad news: PowerGrasp comes as a mobile Java jar installer. Trying to access the file system (to read and make compressed files) makes our phone pop up a security warning for every file or folder you open. And because PowerGrasp is unsigned there's no way to tell your phone to stop throwing endless repetitive warnings at you. This makes PowerGrasp unusable on many Nokias.

The good news: you don't need PowerGrasp. Bluetooth File Transfer Lite can handle zip, tar, jar, nth, and thm archives, and you can switch off the security warnings for this program in Symbian's application manager. If you need to open (but not create) rar files, FreeUnRAR will do the job. MobileRar unpacks zip, rar, and 7z files, and file manager X-plore can extract zip, rar, and jar archives.
