This version should work with both WP 1.5.2 and 2.0. Otherwise, I added an option to insert HTML instead of tags. I may have had options-saving broken at some point, but it seems fixed now.

Filez is a derivative of Photopress that adds a popup file uploader/browser to the Quicktags toolbar. I find it’s useful for uploading and making links to things like zipped plugin files.
Installation and use: Extract the archive in your WordPress plugins folder. Activate the plugin. Create a folder named ‘files’ under ‘wp-content’ and make it writable. You can give it a different name or put it somewhere else but you’ll need to configure some options at Options:Filez. Upload and browse files using the Filez button on the Quicktags toolbar. Manage your uploaded files at Manage:Filez.
Download Filez 0.1: filez.zip.
Feedback request: If you use Photopress and try Filez, let me know if you prefer the single-button-launched multi-purpose popup tool in Filez better than the separate buttons and popups in Photopress.
