Can I del 35 Gigs of old failed DL data in C:\User\xxx ?

[retired205]

I have been trying to find out why my C: drive is so clogged, and discovered all these 'btih: xxx" files of varying lengths, some like 289 mbytes, sitting in a User directory with 5/2016 dates and all labeled as "Partial Downloads". My current queue in Shareaza is all from November (2016) so I know these are all old. FWIW, I am running Win 7 Home. Any reason I can't/shouldn't just blow them all away to Recycle Bin?
