ID:125078 Cannot import settings. Settings file <name> has unrecognized file extension
CAUSE: You attempted to import the specified settings file, but the Intel Quartus Prime software cannot import the file because it does not recognize the file extension. The Intel Quartus Prime software can only import settings files with the file extensions .qsf, .csv, .txt, and .esf. If you created a Comma-Separated Value file (.csv), Text file (.txt), or created or were given an Entity Settings file (.esf) that contains project settings but has a file extension other than .qsf, .csv, .txt, or .esf, respectively, the Intel Quartus Prime software cannot import the settings.
ACTION: Import a settings file that has a valid file extension, or, depending on the contents of the file, change the file extension as appropriate to .qsf, .csv, .txt, or .esf.
