WinAce is a 32-Bit GUI (Windows95/98/ME/NT 4.x/2000/XP) for the new and widely popular compression format ACE.

The program's main purpose is to provide the user with a means to create, modify or extract compressed files of different types.

In addition to the Windows version there is a DOS version available which also includes an easy-to-use shell and several commandline versions for various operating systems (DOS, Win32 and OS/2 as of 6/99).

The compression features of WinAce are not limited to ACE alone - other popular formats, like the common and widely used ZIP format can be both used for compression and extraction of data files.

Since handling archives is very similar to handling files and directories, WinAce can also be used as a file manager shell. It supports operations like copying, moving or deleting files as well as viewing text and commonly used graphic files.
