Editor scripts can't access persistentDataPath, Unothorized Exception [SOVED]

Hello,

I need my Editor scripts to save a Json to somewhere in my drive, and both persistentDataPath and StreamingAssets give me Unauthorized Access Exceptions.
Note that:

• I can access them just fine when my game is running from other sripts
  
• I've checked the permissions
• I've disabled antiviruses

[ISSUE SOLVED]

For posterity:
I was calling System.IO.File.WriteAllText(path, JsonSaveString); from a static method in a static class.

Putting it back into the MonoBehaviour seems to have solved the problem.
