Welcome to jEdit! It's an extremely powerful text editor that can do many customizable things. You will be richly rewarded if you take the time to learn about shortcuts, macros, beanshell scripting and plugins.

jEdit is a java app so the file associations are handled differently than normal win32 apps (I'm assuming you're using a flavor of Windows). Here are two suggestions:

OPTION 1 - use "Open with jEdit" from contextual menu
jEdit should have put an entry into the registry to support opening ANY file with jEdit. Right-mouse click on any file and you sould see an option to "Open with jEdit"

If that is not there, you can use regedit to add HKEY_CLASSES_ROOT/*/Shell/Open with jEdit/command with a value that looks like:
"C:\Program Files\Java\jdk1.5.0_06\bin\javaw.exe" -Xmx64m -Xmx320m -jar "C:\Program Files\jEdit 4.3pre4\jedit.jar" -reuseview "%1"

*** Make sure to change the paths for javaw.exe and jedit.jar to match your setup. ***

1. Open an Windows explorer window, select "Tools"/"Folder Options..." and click the "File Types" tab
2. Locate and click on the file type you want to update
3. Click the [Advanced] button
4. Now you have to choose if (1) jEdit is to be the default editor or (2) you just want to use jEdit some of the time

   if (1):

   • select the "Open" Action click [Edit...] button
   • in the field labelled "Application used to perform action:", paste the same command used in OPTION 1
   • click [OK] button to close this dialog box and all its parent dialog boxes

   if (2):

   • modify existing Action (eg. "Edit with Dreamweaver") by selecting it and clicking [Edit...]. Follow steps for (1) and optionally modify the Action description
   • add Action by clicking [New...] button. Follow steps outlined in (1) and add an Action description

Good luck,
