Here's a quick little guide on how to free up all that space taken by DayZ's intrusive and invasive Crash Log Tracker.
Hope this helps free up a bunch of space you thought you'd lost.
@echo off
del /s /q "C:\Users\INSERTPCNAME\AppData\Local\DayZ\*.*"
for /d %%p in ("C:\Users\INSERTPCNAME\AppData\Local\DayZ\*.* do rmdir "??p" /s /q
exit
It's that simple. Have fun!
