How do I disable previewing a given file type or group of files?

[Etpoh]

Hi. Can you please tell me how I can disable not the whole preview (Alt + P) but only a certain type of files, for example: pdf. Pdf takes a long time to open on my not new laptop. Thanks

To disable PDF previews system wide:

• From the Start menu, search for:
  regedit
• Right click Registry Editor and click Run as Administrator.
• In the Registry Editor, navigate to:
  HKEY_CLASSES_ROOT\.pdf\ShellEx\{8895b1c6-b41f-4c1c-a562-0d564250836f}
  Rename this {8895b1c6-b41f-4c1c-a562-0d564250836f} key to:
  _{8895b1c6-b41f-4c1c-a562-0d564250836f}
  (add a _ prefix)

(remove the _ prefix if you wish to revert)



To disable the PDF preview handler in Everything 1.5:

• In Everything 1.5, from the Tools menu, click Options.
• Click the Advanced tab on the left.
• To the right of Show settings containing, search for:
  ifilter
• Select content_ifilter_handlers.
• Set the value to: [{"filter":"*.pdf","handler":""}]
• Click OK.
