Visualize is very slow to open a small file

It takes me about two hours to open the CAMARO file (which should normally open instantly) ideas on possible solutions?

Are your files local or on the network?

@todesco: The file in question is a demo file stored by default in the documents, so locally.

On the other hand, did it work before? What have you changed since then (Shift, driver...)?

Look at the Resource Monitor in the Task Manager. See if other processes are taking up memory and CPU. See also the level of use of the PC.

I tried everything, network, local and it takes me + 1 hour for the Camaro to open!! Before loading a large file everything worked fine, it was only after loading this file that my problems started. FYI the computer is new, it is 3 days old..  SSD 32GB RAM, Nvidia K5100M...

This file?
