I go into Snapper Mail 2.0 (Beta) then create a new mail message.. Then click the attach option.. It will then allow you to open the SD card. Simply navigate to the program you want then click the File Name you want ONLY... Don't check the box next to it.. It will bring up another menu that will allow you to Beam, Move, Copy, etc.... Just hit Copy and then select HANDHELD as the destination...

Bam all ready to go...

I have BackupMAN with a basic copy of a stable enviroment... When I don't want the other apps I loaded from the SD card anymore I just hit restore... If I ever want them again I copy em down..
