It's also worth pointing out that if you right click on Sonar in the CCC update list, to bring up the rollback menu, there is an option there to "delete files."

Thank you, Sharke! I kept wondering why my C: drive was filling up, even though I had relocated Cakewalk Content to a different drive. Now, instead of 32 GB free out of 237 GB, I have 98 GB free. Phew, that feels better!

Holy crap. More than 30GB here.
 
Let it be written, that on this day - June 17, 2016 - Cakewalk user "Sharke" has officially won the internet!!!

I've had mine going to my Audio hard drive since the beginning. It's the 3rd HD in my desktop PC.
 
That is a good reminder Sharke.....................

In case some of you weren't aware, the CC downloads update files to a folder which you can specify in the CC options, but which defaults to your system drive. For those of you with large system drives this may not be a problem, but if like me you have limited space on an SSD (mine is 250GB) then you might find yourself literally running out of drive space if you don't keep on top of it. This happened to me last night, for the first time in my life I found myself getting "drive full" errors and found that I only had about 50MB free on my system drive. Quickly located the biggest culprit to the CC download folder which was bursting with many GB of files, many of them well past their sell by date!
 
I deleted them all to free up space and then decided to move the folder location to my data drive, which at 2TB can spare the room. But there is nothing to stop this folder growing unless you manually delete files. Perhaps the Bakers should implement some kind of download folder size limit specifiable by the user, with the oldest files being deleted once this limit has been reached. Just a thought. 

Many thanks for posting this as I wondered why my main drive was quickly running low on space.
 

Good to see people getting some drive space back!
 
Here's another little tip: if you use CCleaner on a regular basis, you can add your CC download folder to a custom list of folders to clean. Just go to Options->Include and add the folder. Every time you run the Cleaner function of CCleaner, it will empty your download folder. I always get a few GB back when using CCleaner anyway, so adding the CC download folder just makes it even better. And what an apt name! CCleaner.....
 
I don't use the registry cleaner part of the app, I've never been comfortable with them because who knows what they're doing in there. 

Saved me 32 GB here,
 
Thanks guys.

Good reminder! ..40GB DELETE

Something else that might help to clean up some other additional space, especially if you are on Windows 10 and have had it for long enough to see one of the full updates, which can create a windows.old folder.  You can't "just" delete the folder, but you can do a disk cleanup.  You need an additional option selected to see this:
 
Go to start.  Type clean and then click the disk cleanup option that comes up.  Then (important) on the resulting, dialog, click the "clean up system files".  When that reads the disk, scroll through the resulting list.  I just located about 2gb of stuff and I don't have a windows.old folder at the moment.  If you do, you would likely find 20gb or so.
 
Hope this helps others to regain even more space.
