What is an ACE file?

ACE files mostly belong to WinRAR by WinRar. ACE is the native file format for the WinAce file compression and archiving software from e-merge.

  • Proprietary nature: Created by Marcel Lemke and bought by e-merge, ACE uses a proprietary compression algorithm. This means that eACE files can only be compressed using WinAce. However, e-merge has released a decompression library named unace.dll, through which any third-party application can open ACE archives. The ACE format uses 160-bit Blowfish encryption.
  • Issues: ACE has been used to send malware via e-mail, and the format is no longer maintained by its developers, so it is advised to not open an unknown ACE archive.

Other Uses:ACE is the data exchange format used by the AceDB bioinformatics database. In this case, it is a text file. The extension is also associated with Jupiter Ace, a home computer from the early 1980s. The format linked to Jupiter Ace is a memory dump, or snapshot, format. Microsoft Train Simulator uses an extension named ACE as a texture file for the game.

How to open an ACE file

You need a suitable software like WinRAR to open an ACE file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ACE file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ACE file directly in the browser:.
