How to Restore Your Library from a GemPack

Unpacking a new tablet or setting up a replacement phone is an exciting moment, but rebuilding an extensive reading library from scratch can feel daunting. Re-importing files one by one usually means starting over with lost bookmarks, erased highlights, and broken study decks.

With GemReader, restoring your reading world requires only a few taps. Importing a previously saved .gempack file instantly reconstructs your nested collections, restores your 6-color highlights and notes, and returns you to the exact sentence you were reading.

To restore your library from a backup, make sure you have:

• Platforms: GemReader installed on your target phone or tablet.
• Backup File: A valid .gempack archive accessible from device storage, an SD card, or connected drive.
• Password: The encryption password you configured when creating the backup (if password protected).

1. 1
   Launch GemReader on your device and navigate to the main Library screen.
2. 2
   Tap the + button in the top right header (or the floating action button at the bottom right).
3. 3
   In the pop-up menu, tap Import books.
4. 4
   Browse your file manager to locate your .gempack archive and select it.
5. 5
   If the backup was encrypted with a password, a secure prompt will appear. Enter your backup password and tap Unlock.
6. 6
   GemReader will inspect the package, verify data integrity, and display a summary showing the number of books, collections, and annotations found.
7. 7
   Tap Restore Library. The books and shelf structures will appear on your screen immediately, ready to open.

• Safe Merging Without Overwrites: Restoring a GemPack safely merges incoming titles with any books already on your device. Existing books and notes will never be deleted or overwritten.
• FSRS-5 Scheduling Preserved: Spaced repetition memory flashcards retain their exact review intervals and stability metrics, allowing your daily study habits to continue without interruption.
• Adequate Free Space: Ensure your new device has sufficient storage space before restoring large archives that include companion audio files or extensive PDF collections.
