Preserve the remaining files first. A missing entry in Transfers does not necessarily mean its downloaded data has vanished. Close eMule and make a separate copy of the complete Temporary folder before attempting recovery.

Check whether the client is looking in the wrong place

Record the Temporary paths shown in the current installation. Compare them with the folders used before the crash, update or move. An available drive with a changed letter, a different Windows user or a second eMule installation can explain why a familiar list appears empty.

If the directory is simply wrong, restore the correct path using the client's preferences and restart as required. Avoid creating a fresh empty folder and treating it as proof that the old files have disappeared.

Understand the numbered files

A transfer commonly has a numbered .part data file and a matching .part.met metadata file, with a .part.met.bak backup when available. Metadata describes the download and its state. It is not the downloaded content itself.

Read complete filenames, including extensions. Keep each numbered set together and keep separate installations' folders apart. Renaming an arbitrary large file to a video or archive extension does not reconstruct the missing metadata or demonstrate that the file is complete.

Make a recovery copy you can return to

  1. Close eMule normally if it is still running.
  2. Copy the entire affected Temporary directory to a private backup location.
  3. Confirm that the copy includes data, metadata and available backup files.
  4. Save the relevant error message and the affected transfer's number.

Perform this before testing a replacement. A backup produced after several failed changes may no longer contain the starting state you need. If the drive itself reports read errors or disconnects, preserve what you can before repeatedly stressing it.

Try a matching metadata backup carefully

The official troubleshooting describes restoring the matching .part.met backup after metadata corruption. With the client closed, preserve the suspect metadata separately, then use a copy of that same transfer's .part.met.bak as its .part.met file. Keep the original backup untouched.

Restart and inspect that transfer. Confirm the expected name, size and progress before making further changes. If the entry returns, the client still needs to validate and use the remaining data; do not assume every previously displayed percentage has been recovered.

If one damaged transfer prevents others loading

The project's recovery guidance suggests isolating downloads and testing matching data-and-metadata sets individually. Use copied working folders and a written record of which set you tested, closing the client between file changes. Do not mix pairs simply because their numbers look similar.

This is a diagnostic method, not a guaranteed repair. If you cannot identify the sets confidently, keep the full backup and seek help with the error text rather than deleting files to make the warning disappear.

When recovery is not possible

Missing data cannot be recreated by a metadata backup alone. Recovery may fail if both metadata copies are damaged or the underlying data is gone. Avoid old recovery-tool downloads of uncertain origin. Once the installation is stable, use the backup guide and check disk space and write errors to reduce repeat failures.
