[LUA] How to copy all files from computer to floppy.

Hi, how would I go about copying all files from a computer into its own folder on a floppy with a LUA program? I was thinking about using the fs.copy action, but I see no way to copy all files with it. Sorry for the nooby question, still new to LUA. Thanks in advance :)/>/>

Split into new topic.

You'll want to iterate through the table returned by fs.list() and use fs.copy() on each file.

fs.copy will copy a file or directory, and you can loop over the files in a directory with fs.list, so…

--ignore list - keys in this table cover what won't be copied
--the "true" is meaningless, this is just a handy way to lookup keys quickly
local ignore={
  disk=true,
  rom=true,
  --anything else you don't want copied add here.
}

--list everything in root folder...
for _,filename in fs.list("")
  --only stuff not in ignore list
  if not ignore[filename] then
	--copy
	fs.copy(filename,"disk/"..filename)
  end
end

This assumes a single disk drive, with disk already inserted, and won't overwrite if same-named files exist on the disk already.

local ignore = {
    ['disk'] = true,
    ['rom'] = true,
}

I don't think you can do it like "disk"=true

ahem. You're right, thanks. Should've been "["disk"]=true" or just "disk=true". Fixed.

13: 'do' expected

What did I do wrong?

The line with a for loop should have a do

for _, filename in fs.list("") do

--ignore list - keys in this table cover what won't be copied
--the "true" is meaningless, this is just a handy way to lookup keys quickly
local ignore={
  ["disk"]=true,
  ["rom"]=true,
  ["cpdf"]=true,
  --anything else you don't want copied add here.
}

--list everything in root folder...
for _,filename in fs.list("") do
  --only stuff not in ignore list
  if not ignore[filename] then
	    --copy
	    fs.copy("disk/"..filename,filename)
  end
end

Tryed copy from disk to root like this:
but got: 11: attempt to call table

Well change the line with the for loop to this

for _, filename in ipairs(fs.list("")) do

That should fix it ;)/>
