I think I have seen this model before, in the days of shareware. Offhand, I don’t remember the name of the tool.
A downside of this is that if you don’t choose the right metric, people might burn through a lot of their uses due to mistakes. Like, to use your input files example, imagine someone accidentally selects a huge directory with more than 100 files and then end up with no free uses left.
Some of this also comes down to overall UX design too, of course.
