Notes about the DCTMP file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The DCTMP file type is primarily associated with 'DC++'. DC++ is an open source client for the Direct Connect protocol. Direct Connect allows you to share files over the internet without restrictions or limits. Incomplete files are given this extension; complete files are renamed to their proper extension after the download.
