--- Comment #5 from Mike Kaganski <[email protected]> --- (In reply to Joachim Urmersbach from comment #4) > I think you did not understand my > problem: The file name "2025.04.06 testdata" is changed to only > "2025.04.ods" that means the part ".06 testdata" is missed!!! To the contrary: I understood your problem, but you didn't understand me: from the application point of view, the last part of the file name after last dot is called "file extension". File extension is often three characters (.TXT); it is also often four characters (.DOCX); but it may be arbitrary - and even with spaces. So in your "2025.04.06 testdata", only human can definitely tell, that "06 testdata" is *not* an extension. From application's point of view, when you change file type, the application needs to decide, *why* it *should* change text like "2025.04.ODS" into "2025.04.XLSX" (i.e., replace the part after the last dot), but "2025.04.06 testdata" into "2025.04.06 testdata.XLSX" (i.e., keep the part after the last dot). As I explained in comment 2, there is a viable heuristic that we could use; but that's a heuristic, and comment 1 discusses the original problem that that heuristic could improve. -- You are receiving this mail because: You are the assignee for the bug.
