New text files are created with uppercase extensions

New text files that are created via Explorer’s New ⇨ Text Document context-menu entry have uppercase extensions.

I searched my registry for TXT (match whole) and found nothing special. Could Notepad++ have changed this?

I am running Windows 7 64-bit and use Office 2003 and Notepad++.

How can I get lowercase extensions again?

  • @Bob, May 5 '11 < Feb 11 '12. nixdagibts’ issue is a subset of Torsten’s problem and would be solved with most of the same steps. – Synetech Dec 2 '12 at 5:52
  • @Synetech Ah, sorry. Misread 11 (without the apostrophe) as 2011. Yea, you're right. – Bob Dec 2 '12 at 5:56
  • I know; the timestamps here can be annoying. I find the over-simplifications like dropping the current year or using “today”, “yesterday”, “five hours ago”, etc. to be irritating like what people complain about Microsoft doing with Windows. – Synetech Dec 2 '12 at 6:02

Consider trying .TXT, because extensions are stored with a preceding dot in HKEY_CLASSES_ROOT.

  • Ah very dumb by me. you are right. Now got 2 hits, deletet them, system recreates them, everything works fine. – nixda Feb 11 '12 at 19:17

Try the following:

  • Open the registry editor (Startregedit)
  • Navigate to the key HKEY_CLASSES_ROOT\.TXT
  • Select File ⇨ Export and save it to a .reg file
  • Open the .reg file in a text-editor (e.g., Notepad)
  • Perform a search-and-replace to replace all instances of .TXT to .txt
  • Save
  • In regedit, delete the key HKEY_CLASSES_ROOT\.TXT
  • Double-click the .reg file and select [Yes] to import/merge it
  • Reboot
  • +1 Thats a good solution too. Especially if .TXT occurs very often – nixda Dec 28 '12 at 18:17
