Noticed that Tixati for Windows allows renaming files to names that are not allowed by OS.

From https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file

"
Do not use the following reserved names for the name of a file:

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9. Also avoid these names followed immediately by an extension; for example, NUL.txt is not recommended.
"

In Windows you can't have files and folders starting with above names and follow with dot
E.g filenames CON.txt, prn.a.jpg and folders AuX.Test, NUL.AA.BB are invalid in Windows, but Tixati can rename files to these names.

If files or folders are named like in above examples they can't be opened.
If you try to open folder with invalid name, following error is received: "The handle is invalid"

Filenames and folders that put forbidden names in middle/end are ok, e.g. these will work: a.CON.txt, Test.prn.aa, a.b.nul
