FAQ​

File path inaccessible error on upload​

  1. Open the browser's extension management page, find this extension, and click "Details"
  2. Enable the "Allow access to file URLs" option
  3. Confirm the path provided is a local absolute path (e.g., C:\Users\Username\Documents\file.pdf), not a relative path, and that the file actually exists
  4. If using a remote file, confirm the URL is complete and directly accessible in the browser — the file should be downloadable
