When is this useful?

If you are switching to aMule from some other ed2k client, you might find out that aMule's temp files aren't compatible with your old client's temp files.

Allthough aMule uses a standard temp file format, this incompatibility issue might happen if you are switching from MlDonkey, eDonkey2000 and some strange xMule versions. This is because these clients use strange temp file formats non-compatible with other client's format (such as eMule's).

Of course, you can use this document to export temp file from aMule too since almost all what will be explained here is extensible to most other ed2k clients.


The best thing to do is to set up a testing Field (please read this document before going on).

Once the testing field is set up, you have two ways to move on. Choose whatever way suits better your needs:

Since it's a local connection, the transfer will be almost as fast as copying the temp files from one place to another.

Once all the files have been downloaded, you can safly remove your old client from your system and have a happy aMule experience ;)


This is very fast, since it will most usually be done on a single machine or between two computers in a same local network.

But the most important advantage is that this method is universal: It makes temp file conversion possible between any two (or even more!) ed2k clients, since they all know the same protocol.


Only full chunks will be downloaded. This is like this because the ed2k protocol defines it this way.

Whether this is a big or a little problem is absolutely random. in 90% of the cases, this will suppose loosing about 5% of the data or less. But if you are downloading lots of little files (less than 10MB for example) the loss could come up to 90% (or even 100% in some few extreme cases).

If you find that the loss is too big, I'd suggest you to finish your current downloads on your old client and then switch to aMule.

Also, you should notice that this will need additional hard disk space (for the original and the new temp file). The amount of disk space needed can be reduced by importing one file after the other in a queue and go deleting the original temp files.

Another method

You can use aMule's optimized import tool, although it only supports some clients' temp files.

You can also check the script at src/utils/scripts/ from aMule's sources to import mldonkey's temp files.
