So I'm creating a program to read sequential-image loops and run them. Right now, using a bit of Daniel Shiffman's listing-files hack, I've got it reading all the images out of /data and running the loop.

What I'm looking for is a way to make this more extensible; i.e., to have subdirectories of /data (or some other folder) with individual sequential loops in them that can be run simultaneously. My first idea was to place the loop reading/displaying in an object, and the name of the subdirectory passed to it, so it could read each one without having to hard-code it all.

Right now I'm using dataPath() to read the data dir, but changing the string to something like "/data/ball" or "../ball" doesn't seem to be working. Also, looking through the dataPath() docs leads me to believe that, upon compiling, the data dir structure is folded into the .jar file in such a way that it can't be read sequentially like that. Is this the case? If so, is there another way, perhaps using something other than dataPath(), to read a folder structure independent of the contents of .jar file?

Thanks, but I'm not sure I follow you. What I'm trying to do is use the the method in the listing-files hack to count the number of files in each subdirectory, so I don't have to keep manually feeding it file names. So unless "file.ext" is a java.io thing (have to check the docs), then I don't think I want that syntax. No?
