The directory in the picture takes up 352M https—repo.packagist.org. Previously all of my forum directory was 120mb compressed and now it is 510mb compressed. this happened over the course of 1 week. I just installed a few plugins in this process.
That's a cache directory for composer, it doesn't necessarily need it but speeds up any composer action. It holds information of other php packages, their versions, dependencies and compatibilities.
can i delete this folder?
