pcall() Not Catching Error

Hi, I'm trying to add error support for a file manager I'm making, but for some reason pcall() isn't catching an error if the file I'm trying to delete is restricted.

if pcall(fs.delete(fileOptionsFile)) then misc.popup("Successfully deleted file.", 2)
else misc.popup("Failed to delete file.", 2)
end

You are calling the function fs.delete() and passing it's return value to pcall.
When using pcall, you should pass the parameters like this:

pcall(function, param1, param2, ...)

Alright, but when I try:

if pcall(fs.delete(), fileOptionsFile) then misc.popup("Successfully deleted file.", 2)
else misc.popup("Failed to delete file.", 2)
end

It says "string expected, got nil" ? I made sure that fileOptionsFile is a string and that the error isn't in misc.popup()

Just pass the function, don't call it, remove the ()
It should be like this:

if pcall(fs.delete, fileOptionsFile) then
    misc.popup("Successfully deleted file.", 2)
else
    misc.popup("Failed to delete file.", 2)
end

Alright, thanks! :mellow:/>/>
