Just experimented and found that Rekordbox never seems to delete old analysis files. For example I have analysis files for Track A. I've done some changes in a 3rd party program and the waveform is not showing up in Rekordbox. So I re-analyzed and new files are generated. However, the old files are also there. Is there a way to clean up these files in the USBANLZ folder so they're no longer taking up space? Only option I have now is to delete the entire folder and re-analyze all tracks to regenerate proper files and save space.
I make it a habit of regularly formatting and re-exporting tracks to my USB drive simply to ensure I don't have unnecessary garbage on there, but at 128GB, I'm not too worried about a few extra 110-140KB analysis files.

Ah, so the export pulls only the latest analyzation files/folders onto the USB?
What about all the extra leftover files on my hard drive? Any way to clean that up? I'm sitting at about 3GB of files in that folder.
Your source drive or export drive?
On my source drive. There are a ton of analysis files that are not being used because I had to regenerate them.
I'll see what our rekordbox team has to say. It would make sense if there was an internal utility to sweep out the unused analysis data.
That would be ideal. I'm imagining a function that touches all files in collection and indexes the analyzation and artwork files referenced by each one and then removes anything that isn't linked.
I wondered why my disk copy time was getting longer and longer and it is because of many of these analysis files. Old files definitely should be removed, I appreciate they are only small in size but my software looks at every one of these files to determine whether to copy it or not.
Pulse was there any feedback from the team on this please?
@Colesy > Sorry for the delay; I've asked for a follow-up on the ticket with the engineers. I expect it caught them at a time they were busy creating the rekordbox 5 foundation. I'll let you know when I hear more.
@Colesy > The rekordbox team has asked if you could tell us which 3rd party application was used to modify the song?
@Pulse > it was the original poster that mentioned they made changes in 3rd party software rather than me.
I think the issue here is that every time a file is analysed in RB an analysis file is created.
This is what you would expect for a new file added to RB but for an existing one the expectation would be that any existing analysis file is updated or if this isn't possible then the old file would be deleted and replaced by a new one, so you only have one analysis file per track in your library at any time.
I don't think this is the case currently and over time a large amount of analysis files build up that are completely redundant.
My issue with this is that I use a program called ChronoSync to make a copies of my hard drive (for back up purposes) and the more of these analysis files that build up the longer it takes ChronoSync to mirror copy the drive - as it is copying all of the analysis files including those that are redundant hence the request to have RB clean these up automatically.
Hope that helps but shout if more info needed.
@Colesy > Sorry, part of the problem with trying to answer multiple users within the same topic - this is why I prefer each user post a new topic with their problem, even if it's related or similar to another.
I'll pass your comments along as well.
Just as a note, you could always use a sync method that copies new/changed files rather than a full mirroring every time. That way all the old files would just stay there and because they're small, it's not that bad in terms of space consumption.
@Pulse > Thanks Pulse. My issue isn't a separate issue it's the same as the original poster which is to clean up/remove old analysis files for the USBANLZ folder.
Cheers for looking into this
While it's the same issue in terms of what the problem is, you're a different user and have a different situation; you use a sync software, he doesn't.
I do use an incremental copy but it still has to check the thousands of the analysis files to see if they are the same and this takes time.
