Programs on SD Card

[mommasboy]

I have a question, and yes I did search, but I couldn't find the answer to it. If I install multiple programs on my SD Card and then I reflash my phone, are pieces of the old programs still on my memory card somewhere. The reason I ask this is because I have a 4gb card and i'm starting to run out of space. I don't have that much music on there maybe like 200 songs and 1 movie thats about 200mb. the rest are cabs, zip files and programs and the programs are mainly games( about 7-10 of them) Other than that thats pretty much it.
