Files download in full but remain DC++ TMP files

Possible reasons : there is not enough disk space on the target disk, DC++ doesn't have rights to write access to the target folder or the target filesystem can't hold the file.
If you checked these and didn't solved your problem please include your DC++ version and what OS do you use.

My Os is XP pro my DC version is 0647 The files in question are still are marked DC++temp

Correctinn the files are marked DVTEMP

DCTEMP sorry

There's no DC++ 0.647. There's DC++: 0.667, 0.687 & 0.697. Out of these 3 clients, what version of DC++ are you referring to?

Your version is more than 3 years old and not supported. Upgrade to the latest version and see if the problem solves itself with the update. Read the Help file for Settings / Downloads to see how downloads work in DC++. You'll find out the problem then it should be one of the reasons mentioned above.

0.674 is the version. Some of the hubs O am on do not allow me to use the latest version

Then ask support from those ones who want to live in the past.

i have the same problem and i use the latest version 0.709 and on the destination disk there is 150Gig of free space who can provide me with an awnser ???

eMTee suggests this article as an answer to your question:
FAQ #277: “I found my finished download stayed in the Unfinished folder with .dctmp extension. If I rename it to the original name and open it looks OK. How come?”.
