SUMMARY
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.

MORE INFORMATION
Microsoft Project for Windows requires the correct file extension to open the following file formats:

NOTE: Other files formats such as .mpp .dbf, .wk* and .xls do not require the extension to open successfully.
