Importing files on the hard drive using the Batch command is complex. Please carefully read in the manual how Batch and Single modes work. Batch keys off the Define Field Order settings and files that match it. If any files exist with different filename field orders (Title - Artist for example, instead of Artist - Title), they will not be imported in Batch mode. Single mode is safer to use.
If you find some files not imported, they also may have experienced an error while importing, which will not import them. We try to only good KMA files into the Songs Database so you don't have to worrry about their quality.
To help further, we would need more facts. For example, in the Import Hard Drive Files screen, what is the Define File Order settings and what is an example filename you use, and do you have more than one filename field order. If so, that is probably the cause of some files not importing.
Again, try to understand the Batch and Single modes by studying the manual. It may not be perfect in describing them, but it is the best we have on their subjects.
