Blindwrite help needed please

hi from a newbie,

i have the latest blindwrite

i have 3 files for a prog called “Railroad” located in a folder on my hd

file1 railroad.bws
file2 railroad.bwa
file3 railroad.bwt

my prob is that i cannot direct blindwrite to the folder as the source folder…
does this mean that blindwrite will only read from a disc, and if so should i just burn these 3 files to disc and then ask blindwrite to unpack thei disc to my hardrive so i can unpack it and play the game…

many many thanks for any help any one can give
