Hi there
The folder is being re-created because from RoboHelp's
perspective, it's needed. This means that something, somewhere
inside your project you have a reference to the folder.
Unfortunately, from the description and all it would appear
the folder was created as a result of importing content from
Microsoft Word. I say "unfortunately" because this means you must
now don your Sherlock Holmes attire and begin to sleuth. Most often
folders like these are created to house images that came along for
the ride. And sometimes they are referenced in obscure ways by
Word.
The bottom line here is that you are tasked with picking
apart topics searching for references to the folder name. You may
wish to use RoboHelp's Multi-File Find and Replace utility to
narrow down the reference. Just us the text "_files" and scan all
your HTML files. Odds are you will find it referenced in at least
one and maybe more topics.
Once you figure out where the reference is occurring, you may
then amend the links. After you do that, you should be able to
delete the unwanted folder using the RoboHelp UI.
Cheers... Rick
