I am wondering -- I need to send a client a CD full of installers. His 
dialup is too slow to update that way.
If I download the packages and save and burn to a CD is he going to 
have trouble opening them and using them because they were downloaded 
to me?

Also, once in a while I get a file from him (he said sending me 
attachments were 'agonizing' so you know the level of knowledge is not 
high) and it says it won't allow me to save it but somehow I do.
