CCleaner 1.20.118 and eMule

Hi! This is my first time in the forum.

My question is the following.

I?ve been using CCleaner, but a few days ago I installed eMule.

Is it safe to run CCleaner while I am downloading some movies o will it delete the temp files and loose the downloads?

Thank You.

CCleaner doesn't touch the downloads of eMule, just the search history and file hashes.
