Drive C disk space went critically low to almost 0 Gig!
Uninstalled many programs which didn’t help much.
Initially I thought Adobe software cache was the culprit based on this link… but mine was only taking up around 200MB
Which then led me to do a folder by folder size check
C:\Users\”Your Username”\AppData\Roaming\Apple Computer
Took up more than 60Gigs of space… =_= Housekeeping way overdue.
