Data Resource File
From Just Solve the File Format Problem
Data Resource Files are used in the PC game Age of Empires and Age of Empires II for storing game files such as graphics and sound. It is an archive, so a drs file stores other files which then need to be interpreted in their own unique way.
Common files found archived in a drs file:
- Age of Empires Graphics File (.slp)
- WAV (.wav)
Format
char[36] copyright
uint32 version
char[16] unknown
uint32 number_of_groups
uint32 files_offset
struct groups[number_of_groups]
char[4] extension (reversed with an ASCII space character at the end)
uint32 table_offset
uint32 num_table_entries
struct entries[num_table_entries]
uint32 id
uint32 offset
uint32 size
- Files can then be read from the drs file and written to disk using the offset and size of the file given under each entry.
