One of my pet peeves are useless file names. If software generates a file then it will eventually need to be found. File names that are just strings of numbers that make sense only within the context of the software make that needlessly difficult.

Everyone’s Downloads folder is full of files like these:

But it’s trivial to set file names to something meaningful.

This is what Supplybunny outputs:

This takes almost no effort. All it takes is realizing that users want to eventually find the file and then setting a parameter when calling the export.

So, please set better file names.

PS. In Rails, that’s trivial to do using send_data.
