When is this usefull?
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 this clients use strange temp file formats non-compatible with other client's format (such as eMule's).
Once the testing field is set up, you have to ways to move on. Choose whatever way siuts better your needs:
- Search (with a local search), in your aMule client, one-by-one for all the files you were downloading with your old client and go adding them to the download queue.
- Go to your old [client]] and copy the ed2k links of the files in the download queue one-by-one and go adding them into aMule.
Since it's a local connection, the transfer will be almost as fast as copying the temp files from one place to another.
Whether this is a bg 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).
