[1.45][SSP] fs.open() behaves weirdly.

So I've made a local file on my computer called "colors". I attempt to open it with fs.open(), using a program with "colors" as a given argument, which is passed on to fs.open. It gives me the error "Expected string, string". It doesn't work with "/colors", but it works with "color".

Pretty positive that this is because it checks the rom/programs directory first and returns the error, because these files can't be accessed by local computer programs. Is it supposed to behave this way?

You need to specify the mode to open with or it will error. So if you want to read "colors", then use

fs.open("colors", "r") -- "r" is read mode

See the wiki page for fs.open.
