My company is migrating their file storage to OneDrive for Business. According to the MS Knowledge Base at http://support.microsoft.com/en-us/kb/905231 folders that end with _files are not going to be allowed. When I save a web page in Firefox (as Web page, complete), all the auxiliary files associated with that page (like images) are saved in a folder called [web page name]_files. If I try to change the name, I get a message that the saved page won't display properly if I do. I need to be able to save pages for offline use sometimes. How can I do this while avoiding the use of _files in the folder name, and still have my browser find all the files?
