I started receiving "Low Disk Space" warning from Windows.
My local hard disk has 500GB space. My typical disk space footprint has been somewhere between 200GB and 300GB. I hardly run out of disk space. So who is chewing up on my disk space?
I used free disk usage viewer called WinDirStat to find out which folders are taking up the most space. (I used a number of disk usage tools, free and commercial, and WinDirStat is my choice.)
Right off the bat, I saw several unusually large folders.
These folders were under Dropbox's hidden cache folder. The folder contained many .log file (for testing our game, I use Dropbox folder to run the server. I delete .log files periodically, but Dropbox keep these files in the cache in case I ask for "recovering" deleted files.)
I deleted these large folders using WinDirStat. It has a menu to delete files/folders, so you don't have to use Windows Explorer.
Now, I freed up about 300GB of disk space, and I no longer receive the error message.
To delete Dropbox cache folder, you can also follow Dropbox's article on how to clear cache.
