❔ Unique Integer ID GEN from string input
and idk, maybe an additional check in the loop if there are any correct characters left? There's a possibility that someone will for some reason name a file "Abc######" so the loop would continue for 6 more times for no reason, but idk if it makes too much of a difference

It skips the incorrect characters (-), adds the first 6 to the ID, if 6 are already added then it skips through all the other correct chars until there are only 7 left

How about this one? Now there are no queues, only the initial char array

What would you recommend as an alternative? Would an array, where -1 is to be skipped, be a better alternative?

Should probably work fine as long as nobody uses names such as "hhhhhhhhhh" and "hhhhhhhhhhhhhhh" which will then probably generate the same ID

❔ Unique Integer ID GEN from string input
13 characters is quite a lot to work with already. I can divide it in 'half' => 6 and 7 characters Take 6 characters from the beginning of the input And 7 characters from the end of the input Unless the input length is < 13, then I just take every character. That would probably work out fine enough?

Now there's a 13 character limit... Any progress is good.

❔ Unique Integer ID GEN from string input
I could possibly try and reduce the possible characters by also ignoring numbers / or not adding 10 to the letters resulting in a range of 0 to 25 instead of 0 to 35. Numbers are rarely used in my file names anyways so there is little to no risk in there being any collisions with this I suppose.

For ulong limit 18_446_744_073_709_551_615 Testing this method using highest-value character z (int 35) we get a limit of 12 characters, any higher that that and there's an overflow... It's better than my previous 9 character limit but still far away from 32 character limit...

The string input will be a name given to a file in my game so I guess there is no limit to how big these can get, depends on the situation, but most likely not bigger than 32 characters I suppose (even if they are bigger I can just reduce them to 32 chars, with this length there shouldn't be any problems)
