Thank you all for your replies and sorry I didn't thank before! I'll try your ideas asap!
About BaseCamp, it simply doesn't moove caches like before, since I got the laptop I have now, at the time someone told me it was a bug with Windows or something like that... I try every year since then but the problem persists.
I only knew Basecamp as a cache manager, I don't use the GPS for nothing else.
And I can't delete the caches from the GPS directely, there's no option "delete" on caches. I'll try or ideas.
Thanks!!!!
