Get the user's most recently used file

Generally we have a folder or file is not in our application directory, users need to pick access, then we will let the user pick each time, this is not possible.

How do we get the UWP to remember that the user chooses a file or folder, or that the UWP doesn't let users select files each time

There are actually two ways

• Mostrecentlyusedlist

• Futureaccesslist

The first is very simple, the user recently used a file or folder, this can only save 25, I'm here in the pit, he will automatically delete, find the https://msdn.microsoft.com/zh-cn/windows/uwp/files/ How-to-track-recently-used-files-and-folders, in fact, we can use futureaccesslist, this can use 1k, but why only 1k, so little, garbage wr, to give unlimited
