Hey!
Thanks for your suggestion!
Imho that would kind of break the datfiles, by having a dat for each letter or group of letters under the same collection, instead of a single dat of the collection.
I actually think that there were some dats like that loooog ago due to OS limitations or speed, but nowadays it's not that problematic. Still, it shouldn't be that hard to make a script or tool that splits folders by letters or maybe even splits the dats themselves. Maybe that could be a solution for people with similar needs.
A question, do you feel the need to go inside these folders frequently? Can the current versions of rommanagers (such as romvault or cmp) help avoiding that? [haven't touch them in a while]
@Duncan Twain since you work with some of these huge folders, any tips?
