Given your requirements, I don't think it *can* work. There's just no
way to do it.
How can the computer guarantee that billions of possible inputs (file paths)
map to 10,000 unique outputs (4-digit numbers)? It's not possible.
It might be possible if you had control over the format of the input strings,
but it doesn't sound like you do.
Can you maintain a separate database which maps file paths to numbers?
If so, then this is an easy problem. Just keep a lookup table, like so:
filepath number
-------- ------
/home/files/bob/foo.html 0001
/home/files/bob/bar.html 0002
/home/files/steve/recipes/chocolate-cake.html 0003
/home/files/mary/payroll.html 0004
