You can delete log files and the files created by the strategy tester.

Depending on what you are doing it can be considered normal. It should not happen with a simple 1 pair EA.

But in my experience with multi currency EA, trading 28 pairs this and even more happened using every tick based on real ticks over a lengthy test period. The amounts of data add up real fast considering it loads tick data for all 28 pairs. Not only Disk data but also memory.
