How LRGEX Works

LRGEX Restore

How LRGEX Works

The simple version

1. You tell it which folders matter
2. It compresses and stores them in your cloud folder
3. When you reinstall Windows, you click Restore All
4. Everything goes back to where it belongs

That's it. That's the whole product.

The slightly longer version

Backup

• Right-click any folder in Windows Explorer → "Add to LRGEX Restore" (enable once via Tools)
• Or use the Browse button inside the app
• The folder is compressed (tar + zstd) and stored in your cloud-synced folder
• Every time files change, a new backup is created automatically (on schedule)
• Old versions are kept as snapshots (you control how many)

Restore

• Click Restore All (or restore a single folder)
• The app checks every folder before touching anything
• Each folder decompresses to a temporary location first
• Only on full success does it swap into place — never a half-written folder
• Paths automatically adapt to your new Windows username
• If a folder needs admin (Program Files), it tells you clearly

What makes it different

• Portable paths: Uses %USERPROFILE%, %LOCALAPPDATA%, and Windows Known Folder API — survives username changes
• Path healing: If a path references an old username, it automatically replaces it with your current one
• Atomic restore: Decompresses to temp first, swaps on success — your data is never half-restored
• Locked file handling: Files in use are skipped and reported, never crash the backup
