What is an ACE file?

An .ACE file is a WinAce Compressed Archive file. Files that contain the .ace file extension are archive files that have been compressed using the WinAce file archiving utility.

Computer users utilize a file archiving program to combine a large batch of files into a single smaller file. WinAce was a program that could do this, utilizing a proprietary compression algorithm. This proprietary algorithm offered faster compression speeds and a higher compression ratio than many other archiving applications on the market. This allowed the WinAce user to create smaller file archives, saving space on the user's hard drive.

WinAce has been discontinued.
