eraser,what/where does it erase?

i have eraser,but i dont use it too much for unused disk space,because if i leave it on all night it never finishes.where are my deleted files?will eraser have cleaned most of my deleted files,or will there still be deleted files near the end of the erasing?i hope that makes sense,id like to know.thank you

 

thanks,ron.ive tried in safe mode and it does seem to make abit of a difference .1 is quicker,35 takes awhile.
but;what id really like to know is,where are my deleted files.will there be more right at the start of the overwritting,or will there still be many files at the end.because,if there are many more at the beginning id use it more.as it is,as far as i know my most recently deleted files might be right at the end of the overwritting.do you know?

 

i just read through the FAQ,and i dont think it says exactly where old files are stored on the HD.but,ill start doing 1 pass at a time.i think i was mainly going for 35.also,i think i need to get PGP,which ive never really considered before afew days ago,because theres nothing important on HD(credit card no. etc.),plus i looked at it once and it seemed far to complicated.is it difficult or was i in the wrong place?it was awhile ago so it may make alittle more sense now.

 

http://www.pgpi.org/download/ ? is the first email? and the second is that it?

 

http://www.pgpi.org/products/pgp/versions/freeware/winxp/8.0/ i know this is going of subject but it is HD security im thinking about.should i have started a new thread?

 

thank you,i shouldnt think-out-loud like that.im DLing now and ill read the FAQ.i dont know where i was when i first looked at it.probably digging through algorithms thanks for your help,ron.
