What to Do If a Locally Selected Desktop File Cannot Be Found or Fails to Load Later
Check the source file location, the executing machine, and connection status, then re-add the correct file.
Confirm the File Is Still on the Original Computer
Desktop local attachments use file paths, requiring the source file to be accessible during preparation and reading. If after selection the file is moved, renamed, or deleted, or if you switch to another computer, the same attachment name does not guarantee it can still be read. First confirm the actual environment and original file location; do not assume the file content has been fully saved to a location accessible across machines just because the file name still appears in the chat.
Re-add According to the Current Path
After verifying the file exists and the current user has read permissions, remove the invalid old attachment from the input area, then use the file selector to choose the correct location. If metadata cannot be read, prioritize checking the file itself and system access conditions. If continuing an existing task, this indicates the file location has changed; provide the currently available file instead. Do not pretend to update the actual path by arbitrarily modifying the displayed name in the interface.
Handle Connection Errors and File Errors Separately
Failure of the desktop file connection channel may also cause read failures; follow prompts to restore Desktop and wait until ready. If failure occurs during a write operation, first verify the file content, as modifications may have already been completed and direct repeated appending is not allowed. After restoration, first perform read-only access confirmation before continuing subsequent operations. A usable local path does not guarantee the content never leaves the computer; tasks and tool results are still processed according to service data procedures.
