export ipa file for an iPhone application

one of two things...

1. The publishing is still in progress. those files/folders are temp while the publishing is in progress and is usually cleaned up once it's done and the ipa is created.

2. if the packaging fails or stops abnormally, then the temp files/folders don't get cleaned up and the ipa is not created.

Possible reasons (all of which I have had happen to me from time to time):

1. I was having problems with publishing when spybot 2.0 beta was installed, it was Hooking java and causing it to crash. (system your systems application event log for possible java errors) (Flash uses a java compiler)
2. You do not have enough memory... increase the size of the heap in your jvm.ini (just google it, there are tons of reference material on flash memory management)

3. There is some code someplace in your project which is causing the compiler to crap out

If you can't figure it out, try doing a command line ADT build to see if it gives any additional errors that may be surpressed by flash (I've had that happen too)

Good luck.
