I've downloaded a large file that has 7 folders to it. It also has a:

tda
MSInfo Document
13 kb

When I double click any of the 7 folders I see something like this in each:

tda-cs2
BIN File
420,3000 kb

I have Nero installed and I probably need to use it to burn the files but I dont know how. I've tried several times but I know I'm doing something wrong. Thanks in advance.
