### 35.4.4 Deleting MIF files from the project directory

To delete MIF files from the project directory before conversion, see §5.1.3 Reusing or discarding MIF files.

As an alternative to DeleteExistingMIF, you could list *.mif as one of the file types for EmptyOutputFiles. Then, MIF files would be deleted before conversion only when the type of conversion (book vs. single file) is consistent with the setting for EmptyOutputDir (see §35.4.1 Specifying when to delete old files from the project directory). However, if you expect to rerun a conversion from the book file after manually deleting only those MIF files you want to replace, do not list *.mif as a file type for EmptyOutputFiles; all your MIF files will be deleted, regardless of what you check on the Export dialog. Use DeleteExistingMIF instead.
