📥 User Guide

**No installation required**! This is a green tool, every time you want to backup or restore an archive, just run the application.

**Usage Points**:

• **Game running detection**: The tool will detect whether the game is running. Archives can be backed up while the game is running, but archives cannot be restored. This is to prevent data corruption.
• **Automatic Secure Backup**: When restoring an archive, a backup will automatically be created for the current archive, and the new backup will be named accordingly for easy identification.
• **Rename Rules**: When renaming a backup using the tool, the user ID and "Backup_" prefix are preserved. For automatic backups created during restore operations, the "Pre-Restore Backup" identification is also retained.
• **Unlimited backup**: There is no limit on the number of backups.
• **Quick Access**: At the end of the operation interface, there is a button to quickly open the backup folder.
• **Multiple Account Note**: For multiple Steam accounts, the backup will be named after the user ID. **If you use multiple accounts, you need to restore to the correct account based on the user ID**. However, a secure backup is always automatically created before restoring anything.

📁 Backup file location

Backup files are saved in the following location by default:

`My Documents\#Video Game Saves\Nioh 3`

Alternatively, you can also run the following command via **Win + R** for quick access:

`shell:Personal\#Video Game Saves\Nioh 3\`

**Tips**: The `#` sign in the folder name is to allow Windows to display this folder at the top when sorting.
