# Sheetbooks

Soulver saves your sheets into a single library file called a "sheetbook" (with the .sheetbook file extension).

### Syncing a sheetbook between devices

In Soulver's settings, choose "iCloud" as the sheetbook location to sync sheets between Soulver for iPad, iPhone and Mac.

### **Opening a different sheetbook**

Soulver can only open one sheetbook file at a time, so if you open another sheetbook file, your previously open sheetbook will be closed.

You can open a sheetbook by double-clicking a sheetbook file in Finder, or through the Open dialog.

### Sheetbook Backups

Soulver makes daily backups of your sheetbook, just in case. To restore from a backup, go `File > Backups`, select a backup and click "Restore from Backup".
