Hi!
I've searched my ActiveState Documentantion and I've found the following modules:

use Win32::File;
[download]

which you can get the attritubes of folders/files and

use Win32::FileSecurity;
[download]

which you can for example set or unset permission and such things of a file
it should be good if you search Win32 on cpan for further modules/documentation. Hope that helps.
Atnonis!
