I currently use the filemanager plugin. I find that the "additional data" gets deleted when moving files around with that plugin. Cut and paste from the current directory to a newly created directory moves the additional data. Enter the newly created directory, paste it there, the "additional data" is gone.
Anyone else seen this?
I think a better, fully tested, file manager, should be native to octoprint over what is currently available with this plugin.
Thanks for all the work on this project.
