In Flash CS5 possible move converted symbol to any folder automatically after converting. How to do it? Very easy. Just create new file and add there 2 folder ‘images’ and ‘movie clips’

Click to ‘Library root’ link, and you can see ‘Move to folder.. ‘ area, so there choose ‘Library root’, ‘New folder’ or ‘Existing folder’, and your movie clip will be automatically send there.
I used ‘existing folder’
