I tried Googling this and apparently I need some kind of a file system included.
Does anyone know an easy way to simply list all files in a given directory with as little modification as possible?

local file = io.popen("dir /B /A-D "..path, "r")
local file1 = file:read("*l")
local file2 = file:read("*l")
-- ... more files
if filen == nil then
-- no more files
file:close()
end
Unfortunately in Linux, io.popen is not supported, so you need to use os.execute and redirect the output to temporary name.

local tempname = os.tmpname()
os.execute("ls -p "..path.." | grep -v / > "..tempname)
local file = io.open(tempname, "r")
local file1 = file:read("*l")
local file2 = file:read("*l")
-- ... more files
if filen == nil then
-- no more files
file:close()
os.remove(tempname)
end
Is it any faster though?
Mami Tomoe: this is the faster way1
os.execute('rd /s/q "'..dir..'"')

Is it any faster though?
I'm not aware io.enumdir exist, but if it is then yeah it's definitely faster than my solution.
