Google Chrome > Huge History File

I noticed that my new(ish) SSD drive was really running low on space. I've been really careful to map all my user files to my larger HDDs so I didn't anticipate this happening. I tried running Disk Cleanup to no avail. I finally ran WinDirStat and found a huge, 21GB 'History' file in my "C:\Users\[user]\AppData\Local\Google\Chrome\User Data\Default\" folder. I was able to simply delete it (I closed Chrome first, but am not sure if it was necessary). To be fair, I tried clearing my history through Chrome first...no luck. I've heard that a properly configured CCleaner would have done the job as well. Hope this helps someone!
