Conda remove all environments (except root)

Question

I know I can delete a single environment with

 conda remove -n envname --all

but I often create multiple new environments for installing a specifiy package or testing it so I'll regularly end up with 5-10 environments and it's a pain to delete them after one another. Is there an easy way (for windows) to delete all environments except the root-environment?

Answer 1

Removing all directories inside the envs subdirectory that resides inside conda does the job. This is generally in your user folder ~.

~\.conda\envs\
