additional file exist rules

Hello,
I want to suggest an additionally file exist rule.
Imaging you are using your FlashFXP in several environments.
a) file server
b) web server

a) primaly you upload binaries
b) primaly you upload ascii files

so it's useful to seperate ascii and binary file exist rules, e.g. with a checkbox or a tab bar. I was concered if this issue would be solved, but it wasn't. script files perl/php/asp are often changed and have to be uploaded completely without resuming. Huge binary files must be resumed for traffic reasons. I think there's nothing that's against this additional file exist rule.
