So basically, I searched for a simple term 'logic' in a particular folder called VLSI lectures and for some reason, it shows a number of other redundant files

which are basically aliases to the original document and cannot be opened.
See files without the preview icon.
Moreover, if I open any of the aliases, I get the following warning (more of an error in this case).

I've absolutely no idea whats happening in here.
