Key Features

Compression: UltimateZip is first of all a compression tool. It allows creating Zip archives in few seconds. It is also possible to zip multiple files simultaneously for saving precious time.

Extracting archives: this program can deal with almost all Zip archives formats. It can decompress files whatever the original program with which they were created. It can handle ZIP, 7-ZIP, CAB, Bzip2, RAR and many other formats.

Encryption: apart from these functions, UltimateZip offers also the possibility to encrypt archives for their protection against potential piracy. To do this, it uses a powerful AES 256 bit algorithm that is nearly uncrackable.

Repairing corrupted files: this tool is also able to repair corrupted or damaged ZIP and ZIPX archives. Thanks to this option, it offers the ability to retrieve the contents of this kind of archive folders and obtain a fully functional copy.


A portable version of UltimateZip is available on the developer's website. It does not require installation and can be carried everywhere.
