Windows Explorer slow to open "missions" folders

[AnimalMother92]

Alright, this is driving me a bit crazy. Sometime today around the time that Flash decided to update itself (could be unrelated) I noticed my Arma 2 missions folders become laggy. These:

C:\Users\Ryan\Documents\ArmA 2 Other Profiles\Animal%20Mother\missions

Every other folder opens normally, but anything in either of my profile \missions folders have a weird delay when opening and the blue spinning icon comes up.

This is super puzzling to me, I have an Intel SSD, and keep a very clean system. I've run disk cleanups, done multiple reboots etc to no avail. The weirdest bit is that if I move the folder to my desktop or anywhere else, it works perfectly. But when placed back where Arma wants it...the problem returns.

Having my most used folder in Windows become retarded is pretty frustrating, any help would be much appreciated.

Is the folder shared?

Is there any other files in there? Maybe a file that has a corrupt icon?

Does it happen in all display modes? Large icons/small icons/list/detail
