KB Issue
You may see little blue arrows pointing down on your network folders if you have offline files enabled on your computer.
Issue Details
Offline files are displayed in your networking folders with little blue arrows that are pointing downwards.
This behavior is to let you know you have access to the files in the folders.
This behavior can also take up disk space, so beware and make sure you set the settings to something that is not too large. Unless you have a large C:\ drive, you can set it higher to maintain a larger cache of offline data files on your network.
Recreate Issue
Browse your offline folders by browsing your network.
You will see the little blue arrows appear in different places.
