[CCleaner Issue with wiping free space]

I have NO MORE space on my hard drive after performing the erase free space operation. How is this corrected??

[Erase free space has filled up my hard drive]

I've been running the erase free space utility since yesterday, and I've just now gotten a notice by my mac that the hard drive is full. The operation is not complete it looks like, so is this a temporary thing until the operation finalizes, or is this a problem?

 

The operation has done 35 passes and is now on pass 9 of creating a secondary temp file. 

 

I appreciate any help or recommendations.
