Deep Space Sync Automation for BIM 360 Folders

This PowerShell script is used to clean up BIM 360 files and filenames, primarily to support downstream applications such as Revizto.

Code embedded below:

#DISCLAIMER - USE AT YOUR OWN RISK
#NOTE - ONLY WORKS FOR FOLDERS SYNCED WITH DESKTOP CONNECTOR
#WIP1 - should find a way to trigger right click Sync for Autodesk Docs folder FIRST

#Configure - add your monitored folders in the block below
$allfolders = 
    'firstFolderPathHere',
    'lastFolderPathHere'

#WIP2 - We can open explorer with below
#$path = 'C:\Users\lukes\ACCDocs\VBT\Test Project 1\Project Files'
#explorer /select,$path
#Invoke-Expression "explorer '/select,$path'"
