It depends. Makes no difference for most people.

I think most average computer user do not realize that later Windows has done a lot of 'helpers' that may not be safe for newer apps. Kovid moved the default location because the old one landed in 'the cloud' (violation of not on a network drive requirement). Windows was just try to save users that did not do backups from themselves when they added the cloud drive by default.

[JSWolf]

If it is OneDrive or some other cloud software in the way, moving the library is a good idea so the cloud software will not be able to see it.

[BetterRed]

By default Windows syncs three folders to Onedrive for each user: Desktop, Documents, and Pictures. Anything else must be added by the user.

Calibre used to put its default library in Documents, it now puts it in %UserHome%.

But some program is looking in Users and locking things.

I knew the answer to that for NT from 1994 to about 2007. I can't answer it now, but I see some useful comments.
A lot has changed. Some offices back in 1996 to 2007 used Roaming Profiles and a Domain Controller / Server. Log in got very very slow on changing to a different workstation if there were a lot of user files (I forget how logout was affected/shutdown). If you only used your data-files on ONE workstation, it was best to store those somewhere else outside Users. Never used OneDrive and have had little use of Vista/W7 and Win10. NT3.5x, NT 4.0, XP and Server 2000 (not Workstation) were the ones I used most. In the end many offices had to assign workstations and even abandon Roaming Profiles (some WS maybe only 10 Mbps LAN). Later laptops (from about 2006) were the default and so no issue.

I suspect the current Calibre Library default on Windows is fine as Kovid is very through and there are plenty of users here.

Nothing like a user complaining that it takes them over 40 minutes to log in. Turned out that part of their roaming profile was multiple gigabyte video files on their desktop. Since we had enabled deleting cached copies of roaming profiles, they got to download those files from their network profile every logon. Shutdown/log out was slowed down a bit but only 10-15 seconds.

Oops.

It sounded like a nice idea before one analysed it, the idea you could use ANY PC in the office and it automatically had a local copy of all your stuff.
Of course changes to user account or other mysterious things could result in deletion of all user files on the workstation and server.

I don't at all miss giving commercial IT support. 1991 - 2005. RIP.

A simple way for the user to check if their problem is related folders being locked or not is to revert to version 6.19.1, the checks relating to folder locking were introduced in version 6.20:

Release: 6.20 [09 Jun, 2023]
Bug fixes

Windows: Make moving files in the calibre library folder more robust, locking folders in addition to files, before the start of the move

Maybe calibre doesn't have enough access to work from Users.

Last time I looked, by default the user has full control on their \users\<user_name> directory, which rights will be inherited until they run into an inheritance filter. The permission list is Full Control, Modify, Read & execute, List folder contents, Read and Write.

Then you should tell Kovid to change the Windows default library location from %USERHOME% to whatever you think it should be?

c:\calibre library\

Nope: Root folders on a system drive (c is frowned upon. That would be fine foe a second drive /partition (eg d: - z: )
