WinAce is an archiving utility with an easy-to-use interface for creating, extracting, and viewing archives. It includes built-in compression for ACE, ZIP, LHA, and MS CAB formats, and built-in decompression for ACE, ZIP, LHA, MS CAB, RAR, ARJ, ARC, GZIP, TAR, and ZOO formats. You can create multivolume (disk-spanning) archives for ACE and MS CAB formats and self-extracting archives (SFX) for ACE and ZIP formats.

Version 2.2 adds support for Windows Terminal Servers, adds compatibility with Windows XP themes, and fixes compatibility issues with RAR 3.0 archives.
