Hey there, 

So, whenever I try to pin more than 1 folder to my quick access sidebar, I keep getting the error message "insufficient disk space available". 

I've tried a few things on my PC (running Windows 10) like deleting files, clearing the trash bin, and running a disk cleanup. 

I also cleaned out the trash bin and removed unnecessary files in my Box account, which has 3.4TB of space. 

Even after uninstalling and reinstalling the Box application and clearing out leftover registries, the issue still persists. 

I would really appreciate any help you could offer. Thanks a bunch!
