This line does not take windows paths into account such as \\server\directorypath. So, how about: 
```
# CHECK IF USER SET A FULL SERVER PATH TO the "system" FOLDER
if ("/" is not in gSystemFolder) or ((byte 1 of gSystemFolder is not "/") and (byte 1 to 2 of gSystemFolder is not "\\")) then
# IT IS A RELATIVE PATH, SO WE PREPEND THE ROOT PATH
. . .
```
