On my computer, the ".limpc" folder appears to contain cached data and logs for Farlight Games, the global publishing brand of Lilith Games.
Here's a list of games they've published on PC:
- AFK Journey
- Call of Dragons
- Farlight 84
- Warpath
- etc.
If you've played one of their games, that's probably why you have this folder on your machine.
It should be safe to delete the game's logs and cached data.
Hope that helps!
