28,986,131 | I need to load 1460 files into a list, from a folder with 163.360 files.

I think some time is wasted enumerating the list and then converting it to a dictionary, so even if it is an O(1) lookup for a dict, creating the dict in the first place is too costly to consider it a viable option for large lists.
