Where does PhpStorm store the Local History?

Question

PhpStorm keeps a Local History of all the files.

Does anyone know where these files are stored?

Answer 1

Local History is stored together with other index/cache files -- you will not be able to read it yourself if you wanted to copy/back up it separately -- it's linked to your current files and will get removed if you use File | Invalidate Caches.. for example.

Exact location varies on OS: Directories used by the IDE to store settings, caches, plugins and logs.

On Windows 7 for PhpStorm v8 it will typically be in C:\Users\USERNAME\.WebIde80\system\LocalHistory folder.
