Created a file and something weird happened.

Aight so I just made a file on my SD card called "AndroidApps" and when I went into it was populated with games? It has
Android_File_Browser_2.apk
ApiDemos.apk
AppInstaller.apk
Bejeweled.apk
com.plox.apk
LunarLander.apk
NineHoleGolf.apk
RSSReader.apk
and ssh.apk

Unless you can play Winmo games on Android and these were left over from winmo phone some how?
I didn't download any of these programs?
