Matlab Compiler: Is "userpath" always there and accessible?

Dear all,
my compiled app needs to store some temporary files in the background. Is it safe to assume that the directory given by userpath will exist on all computers? And that we will always have write access to this folder?
Thanks!!
William

Thanks, I think this is safe enough for me. If someone really wants to break my tool by changing permissions or deleting folders, then he still can, and that is ok. I can still display an appropriate messagebox in this case.
Good point with the userpath reset, I'll add an
if isdeployed;userpath("reset");end

I would probably try using the tempdir and/or tempname functions.

But tempdir doesn't always return a path, right? I have the feeling that userpath might be better, because this directory is apparently always created by Matlab Compiler.

It ought to return a folder name, unless perhaps a user has done something unusual with certain environmental variables. The documentation says that the folder is not guaranteed to exist, but you can check that with exist and use mkdir to create the directory if it does not exist yet.
