FauDrei - why do you want to do this?
The names of sub-folders and files in a calibre library are arbitrary, they could have been created from row ids in the sqlite authors and books tables.
If you really need the same structure on your devices you could try to find a file sync tool that runs on your computer and devices- have a look in
Comparison of file synchronization software - Wikipedia.
Since 2008 I've used Goodsync, if I was making the same decision today I would want to consider Resilio.
