Alright i tried to post this the other day but it so happened that my computer crashed so here goes again:

1. I have an encryption rogram going that uses it's own algorithm as well as a variable algorithm with 6 fields inputted by the user. What my question is is this:
in my For...Next loop for decryption how can I check if a folder exists, if not create it as well as a .txt file inside to place my output? I already have the output in it's own textbox for easy cut and paste.

2. When I try to encrypt/decrypt large documents I get an "Out of memory" error, how can this be avoided?

3. This is a stupid one since i forgot the equation:
How many number combonations are there with 6 fields of up to 99 each?

Thankyou in advance and any signifigant help will earn you a place in my special thanks comments and help readme OooooOOOoo AhhhHHHhhhhh
