Rootfs is full, how do I remove/delete files from drive?

Hi, I recently noticed that my torrents have been receiving a disk full error, thus no complete downloads.  Below is a “df -h”.  Can someone help me to clear the .part and .avi files that may have mistakenly been downloaded into the root?  I am a newb at Linux and am unsure of how to do this.

WDMyCloud:~# df -h

FYI, my **bleep** somehow figured it out.  For those of you that need help (and i see other posts similar to mine), download filezilla.  It’s easier to use than putty and allows you to see a tree structure in window format.  this allowed me to find my files/folders i needed to delete.  My new df -h below…
