Also, it's great that one can still update the calibre library even if the library is on a nas
Putting a shortcut ("C:\Program Files\Calibre2\calibre.exe" --with-library "\\DISKSTATION\web\library1") makes updating the library on the Synology easier.
I currently have two libraries on my Synology which I maintain. Now I don't have to bother with calibre2opds to update the libraries on my Synology
