Returns the extension of a string. (for a file)

If you have a string like "this.is.really.dumb", it'll return "dumb".

+ Code Snippet

function getFtpExtension(name$ as string)
  length = len(name$)
  i = length
  while (mid$(name$, i) <> ".")
      dec i
  endwhile
  ext$ = right$(name$, length - i)
endfunction ext$

it's easy to understand, where's the difficulty ?
it reads the name, but it begins from the end ; it continue to read until the letter is "." => all the others letters it has read are the format

but I think you should add something, Phaelax, because your code may crash the application

+ Code Snippet

function getFtpExtension(name$ as string)
  length = len(name$)
  i = length
  while (mid$(name$, i) <> ".") or i>0
      dec i
  endwhile
  if i>0 then ext$ = right$(name$, length - i) else ext$=""
endfunction ext$

so, if there isn't any . in your file, the code won't crash

The sleeper must awaken !

Maybe it was a joke...
