I've been working on a modification for internal use of File Explorer. Management would like for email messages dragged onto the file system to get the sender and date pre-pended to the subject as the filename. I've written a function that, when presented an EML file, will search the file to find the sender number and date, then return those values as the new filename.



Unfortunately, I've never developed a plugin and am having difficulty figuring out what I need to set up within Eclipse.



Does everything go into one project? How do I stack things in the packages? How do I get the code to find the org.eclipse.swt classes? How do arrange things in the src folder?
