As described in this forum thread:
the user would like to save images from transfer functions into the storage space.
This is doable with a hack, but there should be a standard function to do it.
-> add a function in the tf api to store files in the storage in a dedicated "userspace" folder
-> creating folder should be doable too, but only in "userspace" or any subdirectory
-> "userspace" should be ignored on experiment export and experiment clone
