Sideloading onto SD card

view story

http://androidforums.com – I want to load an app from my computer onto a microSD card to put it into my Galaxy. Should I just drop it onto the card (i.e., "G:\") or should I put it in one of the folders (.android-secure or Android?) or make a new folder for it? Is it even possible? I mean, I know it's possible, but will I be able to install the app from the SD card once I put it back in the phone? TIA (General)
