What does Rekordbox use for file hashing?

[Rednax77]

I have a program that hashes all music files in a directory to locate duplicate tracks so i can delete them.
This works as intended but i need to add more functionality as other users have said they wouldnt use it unless they could see which files have got hotcues on them, so they can only delete the files they dont need.

I have no clue how rekordbox hashes their data, i have used MD5 to create my hashes and am trying with no luck to match them, i can access the hash of a song in the rekordbox6 DB but my hash cannot be found inside a the database.

Example log output of comparing my has to random hashes in rekordbox db

My file size: 39967288
My file hash: c267ba0575323ef6bd95797e3e48bade
Path: /PIONEER/USBANLZ/5eb/039a0-d6c2-4b1a-a85d-8d4e60b2568f/ANLZ0000.DAT

Seperately i wanted to say to you very well done to you for making this

[Rednax77]

sorry i just realised this shouldnt be in the issues section, new to all of this. it may be worth noting i dont need to find the timestamps or any other location of the hotcues, just return number of hotcues a song has to identify whether or not a song has no hotcues

Hey @Rednax77

no worries, converted to a discussion:)
Just to clarify, are you talking about the hashes off the ANLZ files or the music files? The file sizes are also a bit off, so maybe you are comparing the wrong files?

To answer your question though: I have no idea, i also was not able to reproduce the hashes stored in the Rekordbox DB. But i haven't looked into that too much if i'm honest! It could be that Rekordbox only hashes the actual music data (without tags etc), but that's just a guess.
