For me, it did not work. Both the old code and the new code made the simulator and iPhone crash.

I just tried the code in the zip file in a mac project and it worked correctly for me…
If I remember right it does not work in the simulator but does work on the device.

Make sure you are using the zip file and not the pasted code.

Here is what I added to my project to get it to work.

(added the files to the project)
(added: #include “FSStats.h” – to the class where you want to use it)

NSLog(@”%@”, [[[FSStats alloc] initWithFilePath:@”/Users/dallas”] getAvailableDiskSpace]);

Make sure you set the path correctly and you have permissions (I dont remember what happens if the path is incorrect or if you dont have permissions, so check this to start)

Hope this helps

Hi Dallas. Thanks for sharing this. I tried running the classes you posted in an application, but it always crashes (both simulator and device). Have others got this working as is?
