Efficiency/performance questions would be important if we would process thousands of such files per second, but this is not the case, or is it? We read/write these .url files at a pace of maybe 1 file per second maximum, if we are browsing fast, and want to save many bookmarks in a short time. IMHO filesystem efficiency questions never arise for bookmarks of a user of a computer. If one day you want to do some data mining on your 10k bookmarks, it will probably take < 1 second, even if done with Python. Do you see a real-life situation for which reading a .url in 1 µs instead of 100 µs would make any difference? (If you're speaking about search/querying, then the OS search feature does it for us)
