How to create folders in a patch?

Stephane Letz

Hi,

We need to create folders from a Max patch on both OSX (universal) and Windows.

1) are they any standard and simple (no java based..) way to do that?

2) are they any third party objects available?

3) we tried to develop our C external but get very confused by the path syntax (like "MacOSX Tiger:/Applications/toto") that mixes ":" and "/" separators). Moreover the "conformpath" help says that "old colon style format" and "the new slash style" may be used... Are they any *clear* explanations of path management in Max, and of what external code would be supposed to do?

Thanks

on os x, use the shell exterenal and send it the message:
"mkdir /path/to/new/directory"

I need to create folders with accentued letters and spaces... not the unix way

OS X only - this is where the platforms are really different

below's the function, it even uses max's path utilities...
