Folder 'python_packages' takes up 300 GB storage space -

Today my drive reached capacity to my great surprise - I though I had about 4-500 GB free. Turns out after quite a bit of searching through the drives, that the installed packages under PyCharm accounts for most of this.

As in the title: the folder 'python_packages', a subfolder to the PyCharm folder, takes up about 300 GB storage space in itself.

My idea was to generate a list of all installed packages/modules, but I haven't found a way to do this.

Any tips for how to approach this? Seems to me the packages I have should at move take up something like 5-10GB.
