I'm not sure to understand exactly what your trying to do here.How do I auto rename a bunch of APKs?

But let say if it is something like: you have 2 apps called "Settings.apk" and "Browser.apk", selecting (highlighting) both and then pressing the rename button (the underlined capital "A" icon) and selecting "Auto rename" option, would change both names to something like: "Settings_6.0.1.apk" and "Browser_6.0.1.apk" - which is basically the app name and version number.
But I'm pretty sure you've must have tried that, so again I'm not sure what you're trying to do exactly.
