Whoops... Did not realize it's StarBurn SDK and not StarBurn question
OK, I've moved the thread here.Upcoming version of StarBurn is going to have StarBurn_UDF2_FileAttributesSet(...) API call allowing you to control two attributes: hidden and deleted (STARBURN_FILE_ATTRIBUTE_HIDDEN and STARBURN_FILE_ATTRIBUTE_DELETED). We don't allow users to play with STARBURN_FILE_ATTRIBUTE_DIRECTORY b/c of the obvious reasons and UDF does not implement archive and read-only ones.
P.S. You can read currently set attributes with StarBurn_UDF2_FileQuery(...) and StarBurn_UDF2_DirectoryQuery(...) API calls.
