For easier rights management and avoiding "shared folder" ****, we opted to have one shared folder across our company with sub-folders for each department.

Said folder is shared with our accounting department.

I moved the folder "Invoices from box" from my root folder to the accounting department sub folder but each month when an invoice is issued it appears again in my root folder.

I propose that box.com remembers the folder ID of the "Invoices from box" folder and used that instead of the absolute path of the folder to drop their invoices.
