An XEF file is a file that has been encrypted by E-merge WinAce, a discontinued archive and encryption utility. It contains a document, image, video, or other type of file, which has been encrypted to prevent unauthorized access. To open an XEF file, you must know the password used to encrypt it.
More Information
WinAce is an archiving and file encryption utility that was available for Windows. It allowed users to package files in compressed archives (typically saved in WinAce's proprietary .ACE archive format) and encrypt individual files, using a variety of encryption methods.
To encrypt a file with WinAce, users:
- Selected the file in WinAce's file explorer.
- Selected from WinAce's menu bar.
- Specified their desired password and encryption method.

WinAce then created an encrypted copy of the user's file, saved as an XEF file.
Optionally, a user could choose whether to include the original file's name in the encrypted file's name, or to set the encrypted file's name randomly. They could also choose to have WinAce delete the original, unencrypted file as part of the encryption process.
