MyWinLocker is a Microsoft Windows utility for protecting user files with encryption and password access. The VMDF format is used for the virtual drives that the software creates.
A .vmdf file contains the encrypted contents of a virtual drive. MyWinLocker manages the drive and makes its files available after the correct password is supplied.
VMDF is intended for use with MyWinLocker rather than as a general-purpose storage or exchange format, so access depends on compatible MyWinLocker software.
Open the .vmdf file with MyWinLocker on Microsoft Windows. The software should recognize the file as an encrypted virtual drive and request its password.
Without the password and compatible MyWinLocker software, the encrypted contents cannot normally be accessed.
A .vmdf file is not normally converted directly to another file format. Open or mount the virtual drive in MyWinLocker, unlock it, and copy the needed files to ordinary storage.
If MyWinLocker cannot access the drive, a conversion utility is unlikely to recover or convert its encrypted contents.
