Tridion provides great WebDAV functionality to browse and add items to Tridion. I use this to bulk upload images to Tridion. The unfortunate thing is the WebDAV protocol is very quirky and the client is implemented differently per OS.
One trick I use is to open the WebDAV url with Microsoft Office Word.
1. Open Word
2. File, open
3. Insert webdav url. Mine is: http://tridcms.test.tomtom.com/webdav
4. Type your credentials and smile. You’re connected to the CMS via WebDAV.
5. I usually go back to Windows Explorer, copy a bunch of images, and then in Word paste them.
