Bug report • Re: [BUG]: preview_single_handler_instance not working as expected

Moved to the Everything 1.5 Alpha forum.
Please post 1.5 Alpha related questions and reports there.

I think you mixed up "preview_single_handler_instance" and "preview_handlers" ?

To override the system (=Windows) preview setting for use in Everything:

• Start the Registry Editor (regedit.exe)
• Go to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\PreviewHandlers
  Will look something like the following:

• MAke a note of the GUID of the Delphi Preview Handler
• In Everything, go to Menu => Tools => Options => Advanced
• In the Show settings containing field, search for handler
• Select preview_handlers
• If you want to preview txt,log,html and htm files using the Delphi preview handler, set it's value to:

  Code:

  preview_handlers=[{"filter":"*.txt;*.log;*.html;*.htm","handler":"{12345678-abcd-efg-123456789ABC}"}}]

  Where {123....ABC} is the GUID of the Delphi Preview Handler.

P.S IIRC: Delphi puts it's preview handler associations under HKLM, PowerToys under HKCU.
Uninstalling PowerToys leaves you with halfway corrupted registry entries: file extensions that were associated with it do no longer give a preview (at least that was the state of things 2 years ago).

There are ways to remove the PowerToys preview handlers (by editing the registry), which will re-activate the Delphi preview handler for selected file extensions, but I suspect that with the next update the PowerToys ones will be re-installed.
