One disadvantage of the MediaServe Pro panel is LiteSpeed/OpenLiteSpeed directory indexing. If you want a directory of files which is easy in Apache, it's a bit more difficult in LiteSpeed/OpenLiteSpeed, and exacerbated by the distributed nature of the entire panel.
The only solution is to use a single file indexing script like Minixed.
You can simple copy the contents of the Minixed index.php from https://raw.githubusercontent.com/lorenzos/Minixed/refs/heads/master/index.php and access the file manager in MediaServe Pro, create the index.php where you want it, and then use your web browser to access the same folder URL see how easy it was to install!
The only drawback? If you have a hiererchy of nested subfolders, each will need the same index.php moved into it to continue browsing the next level of folders.
