.W01 File Extension

A W01 file is a backup data file created by Samsung Recovery software, a program that comes with Samsung computers to backup and recover data. It contains a partial backup of a computer system that can be restored if all other necessary backup files are present.

W01 files are located in the \SamsungRecovery\ directory. The files are saved in a proprietary format and can only be opened and restored with the Samsung Recovery software used to create them.

NOTE: Samsung Recovery was originally called Recovery Solution but changed to Recovery with the release of version 6, which followed version 5.6.
