I like Andexplore and Astro. They have labels like /SDCARD and /EMMC ok so /EMMC is a little tougher to figure out but it is the internal memory SDCARD is self explanitory. In Andexplore you long press on a file click menu copy paste and copy or cut depending on whether you want to move or copy then you select the file then go to the destination and press menu and select paste and it will move the selected files for you. In Astro I believe you long press and you can select a few then go to a destination and select move and it will move the files you selected to the destination folder. I think you can also do that with copy.
