I am just starting to try Calibre and am very excited about what appears to be a fantastic tool. But I'm having some teething problems.
For years I've kept my library of ebooks on a NAS drive at home, which I reach by using WebDAV. These days I mostly use Macs, and the simplest way to access the library is to start in Finder and use Go > Connect to Server > (enter URL of the share on the NAS drive) > Connect. The first time connecting, enter the password and save it in Keychain. After that, Connect is sufficient.
This works great with Zotero and using the Zotfile extension. My entire library resides in a folder named Zotero_Library. So today, trying to ape this behavior in Calibre, I created a new folder named Calibre_Library with the identical permissions.
But Calibre don't like that. When it first started up it apparently scanned my hard drive and found one book, which it successfully stored in the NAS drive's Calibre library. But when I tried adding books (pdf files) to the library, I got a permission error. Even worse, Calibre seems to break the WebDAV connection altogether, so that other apps can't access the device anymore either. So I have to make another connection manually.
Any suggestions how to make this approach work?
