Possible Duplicate:
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?

Try the following:

  • Open the registry editor (Start ⇨ regedit)
  • 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

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