Actually, the cool thing about dropbox is that even if things are deleted, they can be recovered.
Also I was wondering, could you/we(the DP group) request that people adding APKs to the folder include some form of explanation of the app. either we create a text file and update it or even better, if you add an APK, included a URL link to the Google PLAY or official site page. That way we know if it's a paid app or free and what version it is.
I've tried googling some of the file names without success.
If you/the group like this idea, I can make links for current apks (that I can find).
You can upload your own APK's , just try not to put duplicate's in the folder. Please don't delete anything.
You can share paid apps if you want.
