Mensaje "El archivo no se puede mover al destino seleccionado" Lightroom Classic

[EVH2014]

Hace varios días he tenido este problema al intentar mover carpetas de fotografías de mi Mac a un disco externo que siempre está conectado, aparce una ventana emergente diciendo que "Se ha producido un error al copiar archivos en el destino seleccionado. No se pueden copiar los siguientes archivos:" Y me da la lista de todos los archivos dentro de la carpeta. Aunque no mueve los archivos, sí se crean las carpetas dentro del disco externo.

No entiendo porqué sucede esto si nunca he tenido este problema antes, mi disco funciona perfectamente. Ahora si quiero mover archivos tengo que hacerlo por fuera de Lightroom y en serio es una molestia.

¿Alguna idea para solucionar este problema?

Esta esta ventana que se abre cuando intento mover los archivos.

It is hard to investigate this over the internet, but it is a frequent occurance on Macs, especially after a Mac OS update. It is usually a permissions problem.

Many of us would recommend using Mac Finder (or Windows File Explorer) to transfer large numbers of files or whole folder trees. Lightroom is not a file browser, and when it sometimes drops the ball bad things happen to the files. After the files are transfered outside of Lightroom, in the Lightroom Folders panel, do a "relocate folder" or "find missing folder" on the top-most folder(s) that got moved/copied.

I didn't upgrade my Mac, I actually downgraded it several weeks ago. I understand that lightroom is not file browser, but it does give you the option to move folders so all keeps nice and tidy with all the info on the work I have done to the photos. Also I just noticed that I can't even do that in folders on the Mac's hard drive itself. If it didn't let me move folders around since I started using it like 5 years ago, I wouldn't mind, but since it stopped working and it's making the whole process more complicated and tedious, then I guess I have to ask why is this happening and what can be done to bring it back to normal, especially because when something does not work as it used to, usually it could be a sign that something bigger could be wrong. Changing the method of moving folders does not solve the problem, it's a workaround.

Are these files missing in the Library Thumbnail view at all?

That would be indicated by an "!" (exclamation mark) in the top right corner of the thumbnail preview.

Tengo el mismo error desde que actualice Catalina. Todos los catálogos presentan errores de este tipo. Me estoy volviendo loca.

SOLUCIONADO: 

Te paras sobre la carpeta y pones BOTON DERECHO / ACTUALIZAR UBICACION DE CARPETA, y volves a poner la misma y listo, se soluciona ❤️
