attrib -C on a read only file?

[Rodolfo]

I would like to know if it is possible to change the C attribute on a read only file, without changing anything else.
I tried on two test files on two different systems.
On the first, I did not get any error but the attributes were not changed.
On the second, I go an error.

[F:\work\test]attrib
R__A______C____  F:\work\test\a.txt

[F:\work\test]attrib -c a.txt
R__A______C____ -> R__A___________  F:\work\test\a.txt
TCC: (Sys) The handle is invalid.
"F:\work\test\a.txt"

Thank You and regards

That's a Windows (API) issue, not TCC. But it does make sense if Windows doesn't let you compress/uncompress read-only files.
