Have you encountered a problem with a ACE file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a ACE file here. In the further part of this page we have added a list of programs that should open your ACE file. It is enough you choose a proper application for your operating system, download and install it.


An Ace file, like Zip or Rar, is an archive file containing one or more files that can be reduced in size by a compression algorithm. ACE is a proprietary format that has not been developed since 2007. (current version is 2.69) The ACE compression algorithm is not license free, so ACE archives can only be created by the commercial program WinAce.

The decompression process can be integrated into other programs with the help of a free dll, which is why unpacking routines can be found next to commercial ones as well as in many free pack programs. Winace is a pretty efficient packer, whose compression rates are often much better than zip and still pack at high speed.

In the meantime, the ACE format has lost much of its importance because on the internet ZIP and RAR are the dominant formats and more and more often 7-Zip is used. But since it was a very popular archival format at the turn of the millennium, you can still find a few ACE archives.

How to open a ACE file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the ACE file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a ACE file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support ACE files. At this point we are looking for disk space where the application was installed in and we can link it with a ACE file. Since then, our operating system will use the selected program to support all ACE files.

Other issues

Despite the described problem with ACE there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the ACE file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the ACE file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
