Faster search and restore files from recycle bin

Hello, I’ve accidently deleted a bunch of files in a directory. Now there is the recycle bin feature, however I’ve accidently synced millions of temporary files over the last months as there is no exclude-file feature in SeaDrive client. The recycle bin is unbelievable slow in the web UI and is unable to finish loading, probably because of the history of millions temp. files. Is there any other way to restore the files from recycle bin, maybe via CLI in a faster way?

Thanks, any help is appreciated!
