Error in the data folder

[mgutierreztudelft]

Hello, last day I could access to the data folder correctly. However, now I do not have access and I have not touched anything relevant. I attach a picture where it shows that I am putting the path correctly and despite that, in the "data" folder at the left it does not appear.

Any idea of what could be happening here? without the data I am not able to continue the exercises.
Thanks

The mount line seems fine with me. Can you check if there are files under /home/mgutierrezfern/Downloads/ae4353_dataset?
