Data Migration

FolderRewind supports importing/exporting two data types in Settings:

  • Config data (config.json structure)
  • History data (history.json structure)

Entry​

  1. Open Settings.
  2. Find Data Migration section.
  3. Choose import/export as needed.

Config migration​

Export config​

  1. Click Export Config.
  2. Choose a save path (.json).
  3. Wait for success message.

Import config​

  1. Click Import Config.
  2. Read confirmation prompt and continue.
  3. Select a config JSON file.

Importing config replaces current config data. The app attempts to back up old config as .bak first.

History migration​

Export history​

  1. Click Export History.
  2. Choose a save path (.json).

Import history​

  1. Click Import History.
  2. Select mode:
    • Merge: import only missing entries (deduplicated)
    • Replace: overwrite current history with imported file
  3. Select history JSON and execute.

Replace mode attempts to back up existing history as .bak first.

  1. Install and launch FolderRewind.
  2. Import config.
  3. Import history (usually Merge first).
  4. Open several configs and verify source/target paths are accessible.
  5. Run one manual backup and one restore test.

Notes​

  • Across devices, drive letters and directory structures may differ. Verify path validity after import.
  • Encrypted configs rely on machine-local credential storage. Validate encrypted restore flow first after migration.
