A PATH environment variable editor written in C# and WPF

Greatly inspired by https://patheditor2.codeplex.com/

• finds non-existing directories
• path text is editable, so you can manually edit or copy-paste it
• you can "disable" an entry - it will be removed from PATH and stored in a file so you can easily reenable it
• you can drag directories into the window to add them to the list
