Drastic protection measures for your files and data.
Files containing images or PDF files are located in a special tree structure dedicated to a domain. Catalogger includes a tool that allows the administrator to upload this data to a container directory, a catalog directory, an item in the catalog directory or the main directory of the domain. The file container is not located on the web container and the files are only accessible via a web URL.
It's not a mess there is one folder per catalog item, there is one folder per catalog and one main folder. Not all these directories are in the web container. They are in a protected area accessible only by the url.
