--- Comment #3 from gat gatlinsullivan@yahoo.com --- Austin, I have added you to the CC so that you can either confirm this or mark it as invalid.
winecfg -> "Drives" -> "Show dot files" (checked or unchecked)
with Notepad++ 6.9 on Fedora 23 with Wine 1.9.5 will not show any dot files from the home (~/) directory in the file dialog (Ctrl-O) in Notepad++. I assume that not showing dot files when the "Show dot files" is checked in winecfg is a bug. I'm not sure that that is what the original bug reporter was reporting.
