How many files? I've regularly "printed" my current project to TIF files, and it comprises 32 files and 246 pages. It takes just a couple of minutes to do it manually, simply as follows:
1) open all files at once
2) Select Graphics tool
3) Position mouse cursor over "close" button of top document
4) Repeat "<alt-G>, <alt-X>, <alt-A>, <alt-G>, <enter>, <click>" until no more files are open
It's actually pretty hard to get the above wrong, though I wouldn't want to do it for hundreds of files.
It also helps to have the original files intelligently named!
