RS
application/octet-stream
Magic Bytes
Offset: 0
4D 5A
The RS format is a legacy compiled resource file type developed by Microsoft and various third-party compiler manufacturers to manage binary application components. These files primarily store graphical assets, interface strings, and metadata required by executable programs to function correctly on the host operating system. Although this format shares structural characteristics with executable binaries, it serves as a static data container and is generally considered safe for standard archival purposes in modern computing environments.

const signature = Buffer.from([0x4D, 0x5A]);
return buffer.subarray(0, 2).equals(signature);
}
Go
func IsRS(data []byte) bool {

if len(data) < 2 {

}
return bytes.Equal(data[:2], signature)
