What is a DCTMP File?

Question: What is a DCTMP File?

Did you find a DCTMP file on your computer and wonder what program should open it? Maybe someone emailed you a DCTMP file but you're not sure how to use it. Perhaps you tried to open the DCTMP file but Windows told you that it could not open it.

Before you can open a DCTMP file (assuming it's even a file format that's intended to be viewed or edited), you'll need to determine what kind of file the .DCTMP file extension refers to.

Answer: A file with the DCTMP file extension is a DC++ Incomplete Download file.

Other types of files may also use the DCTMP file extension. If you know of any additional file formats that use the .DCTMP extension, please let me know so I can update this information.

How To Open a DCTMP File:

The easiest way to open a DCTMP file is to double-click on it and let your PC decide which default application should open the file. If no program opens the DCTMP file then you probably don't have an application installed that can view and/or edit DCTMP files.

Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with. See my List of Executable File Extensions for a listing of file extensions to avoid and why.

As of this writing, I don't have information on any specific applications that will view DCTMP files or open DCTMP files for editing. If you know of any, please send me a quick email and let me know the name of the program so I can update this page.

Tip: Use Notepad or another text editor to open the DCTMP file. Many files are text-only files meaning no matter the file extension, a text editor may be able to properly display the file's contents. This may or may not be the case with DCTMP files but it's worth a try.

If you find that an application on your PC does try to open the DCTMP file but it's the wrong application or if you would rather have another installed program open DCTMP files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert a DCTMP File:

There are two main ways to attempt to convert a DCTMP file to another file type:

The first option involving opening the DCTMP file in its native program is preferable because it's both easier and will probably result in a more accurate file conversion. Of course if you don't have a program that opens DCTMP files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the DCTMP file extension) to one that your computer recognizes and expect the newly renamed file to be usable. An actual file format conversion using one of the methods described above must take place in most cases.
