reorganizing assets in content folder crashes 5.7.3

Anyone have a work around to permit re-organizing of the content folder?

I am trying to place all the third party assets under \content\3rd_party\vendor_name\, but it crashes about half the time. Some assets are (so far) unable to be moved without crashing the editor. Additionally, the editor seems to be really dirty/inconsistent about cleaning up folders and redirects. Sometimes it takes a couple restarts before the old folders from a moved asset disappear, despite fixing up the redirectors.

This is flakey AF, and is wasting time without seemingly achieving the goal of organizing things. Any suggestions? or pointers to doco? Using the command line would be fine if that’s what it takes.
