How often are files sent? The ESR informational document notes, "Cycles are assigned sequentially and are increased by increments of one each time a file is sent to an institution." Does this mean every file sent to the college will have a unique name?

Yes. You could receive a file Monday–Friday if there's activity for your code. Each file will have a unique name from the last three number extensions. The file name will appear like this: Your DI code will replace "6003" and the next file will end with 002, the one after that with 003, etc. The three-digit file extension will reset to .001 every January 1.
