Unused samples are not cleaned up once deleted from instruments
Hydrogen version * :1.0.1 Operating system + version : Windows 10 2004 x64 Audio driver + version : N/A
H2 does not seem to clean up the samples for instruments/layers when those samples are no longer part of the drum kit. Two ways to reproduce the problem:
Method 1: Load an existing drum kit, Save As a different name (let's call it Temp), clear all instruments, save. Look in the directory where Temp's samples are stored, and all of the samples originally from the existing drum kit are still there.
Method 2: Load a sample into a layer. Save the drum kit. Oops - I have a better sample, so delete that sample and load a new one. Save the drum kit. Look in the directory where the kit's samples are stored, and both samples are there.
After either of these methods, if you then Save As a brand new drum kit, it only saves the samples that are actually needed, so it knows which ones aren't needed - it just didn't clean them up.
Hi!
in my opinion Hydrogen never had the concept of "owning" the samples which are in the drumkit folders. To Hydrogen, those files are external files which might be used to build a drumkit.
But i suppose that it would make sense to offer a "clean up" functionality (like most DAWs have it for their project directories..) for our drumkit directories.
To me, Hydrogen owns them because
- they're in Hydrogen's directory (c:\users[me].hydrogen since I'm on Windows)
- Hydrogen put them there after I loaded samples from wherever I had been keeping them
A cleanup function would be nice, but unless there's a reason why it would be bad for Hydrogen to clean up after itself, I still think it would be best for it to happen automatically. After all, the average user would probably never go poking around in there and realize that a cleanup was necessary in the first place. (Granted, the samples are probably a tiny fraction of the size of the user's storage, so it's not like they're going to run you out of disk space ... but cleanliness is supposedly a virtue.)

That sounds legit.
I'm not that sure about the automatic cleanup though. E.g, if one creates a new drumkit via an editor, loads it in Hydrogen, and realizes that Hydrogen did delete some of her precious samples because there was a typo in the drumkit.xml file. The annoyance of loosing a sample is in my view way larger than the annoyance of having Hydrogen waste too much storage. But a manual option would be a good idea.
Fair enough - unanticipated data loss is definitely something to be avoided!
Maybe there could be a warning at some point (while saving an drumkit that the user has just edited, for instance) warning the user that there are unused samples, and offering to clean them up or suggesting that the user can do [insert menu path here] if they wish to clean them up. That would deal with my issue of the user never realizing there's junk that ought to be cleaned up, while also ensuring that cleanup is never initiated without the user's action/permission.
Anyway, obviously not a particularly high priority request :-) but it would be nice to have a proper way of handling it, rather than the clunky workaround I've been using (create/edit the drumkit under a temporary name, then when it's finished, copy it to a new name - which only copies the samples that are actually in use - then delete the temporary one).
