Fits Mobile Digital

I really just need to find a way to transfer files from my computer onto the card. Right now the only way I can think of to connect the card to my computer is to put the card in my digital camera. That won't work when I try to drag mp3s into the camera folder.

The way I'm doing it now (and its getting old) is to put the mp3 files onto my mobile phone thru the USB connection, take the mini SD card out of there, then put it in the SD card in the "micro sd card reader" (so it will read the mini card but will fit into the stardard SD card slots, you know what i mean). i can only fit a few song files on the mini card due to its small memory size.

the SD card is essential as the way to store the files in this case so i can't use my external hard drive or anything similar.

i guess all i want to know is if there are any simple ways to directly hook up the SD card to my computer. i hope this i didn't make this more complicated than it needs to be...
