[Help] A couple of questions for those more experienced than me.

I am currently working on a homebrew app that needs to check a folder in a specific directory. Sorry if this is not the correct place to ask this, I found something here but do not believe it is correct. I am fairly new to making this kind of thing; could someone help me with that line of code?

Another thing; I want this app to be able to upload that specific folder to a server where other users can...
