Proline Resource File
Proline Resource Files are archive files as used by F1 Manager Professional. They use the file extension RSC.
Archive files start with a plain ASCII signature "PROLINE Resource File (c) 1997 by PROLINE Software GmbH".
The archive file has no header.
The entries in the archive are described by their size followed by the actual unencoded contents of the entry. The archive itself holds no description of its contents, so the actual offsets must be deduced from the program reading the archive.
There is no compression or special encoding used.
