THEA500 Mini sorts and filters the files that you place in a directory. To keep the user interface responsive and reduce the number of pages a user has to navigate through to find a file, there is an upper limit on the number of files THEA500 will process.
To make it easy to navigate files we recommend splitting them across directories,
perhaps named alphabetically such as A, B or AA-AH, AI-AZ, BA-BH and so on.
