Copy/Delete all

how would i say 'All' like I want to delete 'All' created programs and I want to copy 'All' programs from a floppy?

fs.delete()

This code will delete all files AND folders on the computer:

for i,v in ipairs(fs.list("/")) do fs.delete(v) end

The fs.list("/") returns a list of files and folders in the root of the drive.

Using the above code as base you can transmute it into copy and the floppy thingy.

WARNING: Deletes all files and folders if you run it!!! (of course the ROM folder is safe!)

Hope this helps - And sorry i do not take time to answer your question more detailed!

EDIT: typos

In general, you'd want to use pairs for the file list, cause ipairs can have problems without numbered indexes.

for k,v in pairs(fs.list("/")) do fs.delete(v) end
for k,v in pairs(fs.list("disk")) do fs.copy(v, "/"..v) end

The table fs.list returns is infact numerically indexed, so using ipairs is the best choice.

Im not familer with these…
I see the for loop but what is

 k, v

Maybe you should add fs.isReadOnly()? Otherwise it'll error :P/>
Edit: Also want to point out that you wrote fs.selete

k and v are variables i am assigning to "k"eys and "v"alues of the table returned from pairs. using "for _ in pairs()" will iterate through a table defined in the parentheses, and do the commands you pass to it after the do command.
When I tell fs.list() to use "/" as the variable, it will search in that directory, in this case, the lowest directory available, which is the root directory.

It should still delete all other files just fine, then error out. Also, bleh, spelling.
