From the developer:
MT4 creates log files all over the places, every single day. These log files can start adding up and fill up your hard drive, especially if you write your own EA's and indicators.
If you ever accidentally write an infinite loop or test a very buggy indicator you can generate a log file that will take up most of your disk space without even noticing it. Now it's easy enough to do a search for *.log files in your mt4 folders and push delete.
