Troubleshooting

File Not Found

Lifebook may show File not found! when an image, audio, video, or album file was moved, renamed, deleted, or stored on an unavailable drive.

For a single entry:

  1. Open the entry.
  2. Select Search File.
  3. Choose the file at its new location.

For a photo album:

  1. Open the album.
  2. Select Search Folder.
  3. Choose the folder at its new location.

If the file or folder no longer exists, select Keep entry to leave the entry in Lifebook for later repair, or select Delete entry to remove the broken entry from Lifebook.

To reduce future missing-file issues, enable copying files to the Lifebook data folder.

Thumbnail Looks Blank or Temporary

If a thumbnail is missing but the original file still exists, Lifebook can show a temporary placeholder while it recreates the thumbnail in the background. Wait a moment and keep browsing; the visible entry updates when the thumbnail has been recreated.

If many old generated thumbnails are no longer used, run Settings > Manage Data > Clean Up Thumbnails.

Media File Not Supported

If audio or video cannot be played, Lifebook shows a media failure or unsupported-media message.

Possible causes:

  • The file is corrupt.
  • Windows does not have the required codec.
  • The file extension is supported by Lifebook, but the exact media encoding is not playable on the computer.

Try playing the file in Windows first or converting it to a more common format such as .mp4 or .m4v for video, or .mp3 or .flac for audio.

WebP, HEIC, or HEIF Image Does Not Import

Lifebook includes WebP, HEIC, and HEIF decoding for import and thumbnails, so these files do not require the Microsoft HEIF Image Extensions package for Lifebook import.

If WebP, HEIC, or HEIF images are skipped, fail to import, or do not display:

  • Update Lifebook to the latest version.
  • Install the Microsoft HEIF Image Extensions package if HEIC/HEIF files also need to preview in Windows Photos.
  • Convert the image to another supported format such as .jpg or .png.

No Files Found for Import

This message means Lifebook did not find usable files in the selected files or folders.

Common causes:

  • Files are unsupported.
  • Files were already imported.
  • A selected folder contains no supported files.
  • A selected collection folder contains no image or video files.
  • A document could not be read.

See supported file types.

Duplicate Gallery means the selected photo album folder is already imported.

Choose another folder, or edit the existing album.

Title Empty

Every entry needs a title. If Lifebook shows Title Empty or Entry cannot be saved without a title, enter a title and save again.

Trial Limit Reached

In trial mode, Lifebook allows up to 50 entries.

When the limit is reached:

  • Add and import actions are disabled or limited.
  • Lifebook may import only the number of entries still allowed.
  • The Settings screen may offer a purchase button.

Delete entries or purchase the full version to add more.

Import Ongoing

If you try to quit while importing, Lifebook asks whether to exit anyway. Exiting stops the import. Use the status bar Cancel button when you want to stop intentionally.

Export Failed

Export can fail when:

  • No export folder was selected.
  • There are no entries in the selected date range.
  • The output file cannot be written.
  • The destination folder is not available.

Try another folder, close any open exported document, and export again.

Calendar Import Has No Events

If calendar import says no events were found, the file may not contain supported event data or may be malformed. Lifebook supports .ics and .vcs calendar files.

Outlook Calendar Integration Fails

If enabling Outlook calendar integration fails, Lifebook restores the previous setting and shows the error message. Check that Outlook calendar support is available on the device, then try again.

Missing Entries After Importing a Lifebook Backup

When importing a backup from another computer, Lifebook may find database entries whose original files are not present at the same path. It can offer to delete those missing entries.

If you still have the files, put them back in the expected location or use the overlay recovery buttons to reconnect them.

Lifebook Does Not Start or the Database Cannot Be Read

If Lifebook does not start, or reports that the local data cannot be read, first restart the app and check that Lifebook is up to date in the Microsoft Store.

Do not delete the Lifebook data file unless you already have a current backup. If the problem persists, contact support from Settings > About and mention whether the issue started after an update, import, or restore.
