LAMUS builds on the tool Arbil designed to organize data in a way ready to be archived (http://tla.mpi.nl/tools/tla-tools/arbil/). Arbil thus produces structures which can be uploaded to the archive with the help of LAMUS. Thanks to this interaction it is possible to upload and link entire directories, whole trees (including contents and internal linkages, metadata and resources), to the archive via LAMUS. This potential might appear counter-intuitive to many users, who are more familiar with uploading directories in portions of single files e.g. when sending emails. Yet, this potential and functionality of LAMUS is advantageous for saving time and maintaining the linkages among the files in a directory. We therefore recommend you to make use of this potential already when building in Arbil and uploading files to LAMUS (see also Section 3.2.2).
