Any limit on writing text files?

[dler4]

I'm editing a map to generate statistics to see gold efficiency of each unit, I have a damage meter programmed (stored in a skill as mana cost).

I'd like to run the map and restart fights over and over to see the damage done per unit and write it into a text file so I can later write a custom parser to get the average.

My question: Is it possible to write thousands of text files from 1 game? (e.g. if there are 8 teams with assigned units and each round/fight lasts around a minute, it would write 8 text files for all teams and list each unit's damage for that round)
I would run this overnight and hope to get as many files as possible, are there any limitations or anything I should be aware of?
