Xtool -dd Deduplication

-dd flag instructs xtool to scan for identical compressed streams (such as repeated assets in video games or media libraries). When xtool detects these duplicates, it removes the extra copies from the output file. During the restoration (decoding) process, only one instance of the stream is restored and then copied to all necessary locations, which avoids wasting CPU cycles on redundant decompression. encode.su Key Considerations Stream-Level Detection
