Thx for your quick answer.
I found the problem, it wasn't really the temp-Directory:
This one works with the CD-Rom:
var theDatatoCopy:File = File.applicationDirectory.resolvePath("data");
This one works with USB-Stick and on HDD, but not on CD-ROM:
var theDatatoCopy:File = File.applicationDirectory;
So the problem was not the temporary path, but the
theDatatoCopy.copyToAsync(tempFile, true); call.
I don't know why it's different on CD-ROM and USB, but maybe the problem has to do with, that I shoulnd't copy all the stuff in the appDirectory, since some of the content is used.
That would have been easier with relative path names, but that's ok to handle.
"IOError —.... On Windows, you cannot copy a file that is open or a directory that contains a file that is open."
Thank You!
