I got XML (XML Document) .DS_Store
for each undefined FileType.
BTW: I have a defined FileType for XML Documents whose display string is XML (XML Document).
.
The used code is:
System.DebugLog Item_FI.Type + Chr(9) + Item_FI.Name + EndOfLine
in a loop that scans the contents of a folder.
Not a problem here since it was a simple debug report for me, the .Type check is after that line (not displayed).
But, because I get that too in Xojo 2019r2.1 (slow internet / 19r3 is a too large file to download [hours]).
FWIW.
