Connot delete folder on synology

[MatthiasMarx]

Hello,

The environment. 

MAC, newest OS, LrC, newest version, Synology all updates are also made.

On the discstation there is a folder called: [discstation]/photos

This was mapped on a Windows-based system within LrC

The catalog was moved from windows to the mac.

The link to the mapped folder a discstation appears, but there is no connection.

Other folder than photos on Synology are working. 

I don't need the photos folder attached to LrC, I like to delete them, but it doesn't work, moreover a relink doesn't work as well. 
Error Message "invalid path".

Is there a way, to delete this file in some config files, or what could I do?

Thanks for any comments.

Matthias

You tried to relink, I take that you tried to update the folder location. As you do not need the photos in the LrC catalog, have tried to simply remove the folder?

[MatthiasMarx]

Yes, I did, everything. 

here you see the linked folders are green. They are okay.

The folder who is highlighted, with the root above, couldn't be deleted.

Thank you

Matthias

I wonder what those three dots are for/do??

[MatthiasMarx]

The three dots are only there, without any function. Furthermore, removing on any deeper level of the tree has now success.

I found a solution, but this is not the perfect answer.

I switched from a Windows to a Mac system.

In the Windows world, I had 3 links to a Synology DiskStation. I had linked two paths via a drive letter and the third via a UNC path.

So the 2 were as follows: <Drive letter>:\directory...
UNC: \\<computer name>\<shared directory>\

This UNC path is not readable under Mac, at least I don't know it.
And at this point LrC exits. It appears in the catalog, but a new link is rejected with the message "wrong path".

My solution: I loaded the catalog on my old computer, deleted it under Windows and linked it again under MAC.
