I've ran into another little problem with this. So I've been tweaking the up button to get it to work (if you haven't already noticed it didn't) and I have a question about strings. So when the user presses the up button it adds ..\ to the path which goes up one directory. Since the * is automatically placed the path turns into something like this: llama\*..\ and since the * is there the ..\ doesn't work properly. Is there a way to search a string and remove a certain character or group of characters? I think there is I'm just sure what it would be called. Could someone tell me how to do this? Or just tell me the name of the function so I can look it up.

Thanks, that's exactly what I needed.

Okay well I've got another question about manipulating strings. The problem is that after I press the up button to go one folder up from the llama folder it would look something like this: "llama\..\" in the text box for the path. As you can see it's working without the * (thanks to commander) but I would like to know if there is a way to find a chunk of a string and remove everything after it. I looked in the string section on the GMod Wiki but nothing seemed really obvious. I was thinking there might be a way to do it involving splitting strings but I don't know how I would do this. Could someone give me a point in the right direction?
