34.8.1 Understanding which files can be renamed
You can rename only split and extracted HTML and XML files. You cannot rename the file produced before the first split; that file must have the same name as its FrameMaker file. For example, suppose you are converting a FrameMaker file named models.fm, and splitting it into multiple HTML files. The first file created, which will most likely be empty of content, is named models.htm. Mif2Go generates the names of the rest of the files.
The reason for this requirement is that when Mif2Go checks to see if a referencing (or referenced) file has been created, Mif2Go knows only the name of the FrameMaker file, not the names of split files. So Mif2Go looks for an HTML file with the same name; if it is not there, Mif2Go concludes that the file has not been processed yet, and therefore does not try to update any references it contains to the current file. When Mif2Go does see the originally named file, updating can proceed.
You can have Mif2Go split each FrameMaker file on the very first heading (see §18.2.2.2 Preventing splits that create unwanted files), so that the first output file is empty; then you can leave the empty files behind when you move output files to their final destination. (Do not delete the empty files; doing so could break interfile links. See §20.4.8 Specifying an alternate file sequence for browse links.)
