I notice that whenever I downloaded a .App or compiled a .App file into my Dropbox folder on Windows, Windows uploads the .App file as a folder to Dropbox.

So when my Mac downloads the .App file from Dropbox, it cannot run the .App file and thinks that the file is corrupted.

How can I get Windows to treat and upload .App file just as Mac to Dropbox so that when my Mac downloads the .App file from Dropbox, it could work just fine?

I would place it in an archive. – Ramhound Dec 11 '12 at 14:34
Putting the file into an archive is what I do sometimes. But it is not the most convenient method sometimes. I'm not sure if it has got to do with just Dropbox itself. When I copy the .App file from Windows to a thumbdrive then subsequently transfer it to my Mac, the .App file works. But when I sync the .App file from Windows through Dropbox, my Mac cannot open the .App file. – xenon Dec 11 '12 at 17:37
.app is not a file! You're getting confused because OS X makes it appear a single file to the user. If you don't want Dropbox messing with the folder and files inside or any associated metadata, archive it as suggested above. – Karan Dec 11 '12 at 17:40
