You could also check out
Dave Wolfe's extensions page.. there's lots of great stuff there but the one you're looking for is 'Search and Replace'. After you install that extension, here's what you do:
- Select ALL the symbols & folders you want to rename
- Go to Commands > Search and Replace,
- In the Search For field, don't type anything.. leave it blank
- In the Replace With field, type in a prefix, such as _sc1_
- Select 'Search Selected Items' and click OK.
Because you put nothing in the
Search For field, Search and Replace will rename all the selected library elements with your prefix.
After you've done that and you've imported the scene2 library, you can then just select all of the scene 2 symbols & folders, then repeat the above, but name them _sc2_. Alternatively, you can rename all the elements in their respective .flas before you start combining them.
