When one wants to change the name of a UseModWiki (e.g., CreationMatters to PracticeMatters), can one safely do a change to all files in the alphabet-directories of UseModWiki? Now that there's this .db format i can't count on PlainText anymore, right?

As a practical matter, you would probably get away with this. The .db files are almost plain text--they are simply a set of name/value pairs separated by the special $FS character (which is a superscript-3 character) and a number. There are no raw binary fields on any pages. Still, I would make a backup first.

Actually, the best way may be to use the action=editlinks page (requires admin access) and rename the "CreationMatters" page to "PracticeMatters". When you do this, make sure that the "rename links" checkbox is checked, and all the pages will be changed.

If you (or anyone else) has difficulty with the steps above, let me know and I can write a small script to do the renaming safely. --CliffordAdams
