Windows 7: Purging MFT

That I understand, but this discussion was about purging the MFT of names of files that are already deleted...isn't it? Therefore, if the file does not exist, what difference does it make if the MFT still contains it's name? After reading some on the MFT, I have learned that some very small files may only exist in the MFT, so I'm uncertain how this would apply to them, but I think that the majority of the files are external to it.

That's correct - anything small enough (equal to or smaller than 1K) can be stored in the MFT itself rather than elsewhere on the filesystem to save space (the reference entry in the MFT and the file elsewhere on disk together will be larger than just the file in the MFT, most times).

Thanks for the confirmation, but it seems that my primary question is being side-stepped.

I use CCleaner after most surfing sessions to clean up, mostly for maintenance purposes and also from a safety aspect deleting anything that my AV might have missed. I use the single overwrite option in CCleaner and it has the annoying habit of renaming overwritten files with ZZZZ.ZZZ increasing the number of Z's for each subsequent file. As you can imagine if you do a lot of surfing then these filenames can grow to enormous lengths so I purge occasionally to remove these hoping that this boosts the speed of CCleaner. Not sure if it does but it doesn't take long to do using DS. Other programs use random letters to rename files which seems more sensible to me.
