Subject: Re: [Caml-list] Remove unneeded files in opam

Hi,

> After correct opam configuration, I would like to remove all unneeded fil=
es that opam might keep on disk (cache, .tar.gz of downloaded files, eventu=
ally some remaining compilation tree, ...). Which opam magic command should=
 I apply?

Normally all the build files should already be cleaned-up, but it that's no=
t the case the files live in ~/.opam/<switch>/build
The globally cached archive are stored in ~/.opam/archives
The repository archives are stored in ~/.opam/repo/<repo-name>/archives
If you have local pins, you could find some of the archives in ~/.opam/<swi=
tch>/packages.dev/<pkg-name>

> I've done a bit of googling and looked at the FAQ but found nothing.

Would make sense to add a command in opam to clean the archives, this is no=
w tracked by https://github.com/ocaml/opam/issues/2235

Best,
Thomas
