PRJ: Opening MPX File or Text Based File Requires an Extension
This article was previously published under Q146624
A project saved in a text based format such as .mpx, .txt, or .csv will not
open correctly unless the file has the appropriate extension.
NOTE: This behavior is of particular importance when opening a
text based file created with Microsoft Project for the Macintosh
(which does not require extensions) in Microsoft Project for Windows.
Microsoft Project for Windows requires the correct file extension to open
the following file formats:
Collapse this tableExpand this table
| File Type | Extension |
|---|
| MPX | .mpx |
| MPX 4.0 | .mpx |
| MPX 3.0 | .mpx |
| Text (TAB delimited) | .txt |
| CSV (Comma Separated Value) | .csv |
: Other files formats such as .mpp .dbf, .wk* and .xls do not require the extension to open successfully.

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
Thank you for using kbAlertz.com Feedback System.
