I often create TSV files in LibreOffice Calc. The "automatic file name extension" box required for this process used to be an option when you
File > Save As. It is no longer there since upgrading to LibreOffice 6. Where did it go? How do I get it back?
Something is screwed in the settings. I confirmed this on a separate fresh install. Anyway you need to change
FALSE. If you create TSV files this is good to know.
The setting can be found at Tools > Options > LibreOffice > Advanced > Open Expert Configuration >
