you can use the "GetFileAttributes" function to get the files attributes and use "DeleteFile" to delete them.
for deleting a specific file,you would have something like:
if( GetFileAttributes( lpfilename ) == FILE_ATTRIBUTE_READONLY )
DeleteFile( lpfilename );

DeleteFile( lpfilename );
1. Readonly:
DWORD attr = GetFileAttributes(PathName);
attr &= ~FILE_ATTRIBUTE_READONLY;
SetFileAttributes(PathName, attr );
DeleteFile( PathName );
2. With used files, it is not so easy. You can try to use UnmapViewOfFile() and UnlockFile(), but it works not allways. There are three ways: terminate the program which uses the file, delete it by next reboot or play with assembler codes - look for old samples with assembler.
