RIM file extension - BackupSoft backup file
What is rim file? How to open rim files?
File type specification:
The RIM file extension is used for backup files created with BackupSoft.exe program, that was bundled to some external hard drives sold by Acer or Toshiba.
It seems like the program is not supported in Windows 7, and users might find trouble while restoring backups from .rim files. If you experience this, try to run BackupSoft.exe in Windows XP compatibility mode.
