Hi Mike,
I made a bunch of edits of documentation, saving about a dozen times.
Then I decided to close Notepad++. There was a message that some directory was gone, and did I want to save the file.
I clicked yes, , and that was the end of my file, but I still have the one from yesterday.
Note that Notepad++ will sometimes backup to appdata, and that there is a 3 level backup system under Notepad++/Settings/Preferences/Backup
none, simple, and verbose. In ignorance, mine was set to none. Now it is set to simple.
( I have had some recent file copy problems/weirdness...)
