There may be a set of files you wouldn’t have used for a long time. Since you do not access them that frequently, it makes no sense to copy them every time with your other regular files.
But we often do not know how to exclude or filter such files from being copied. This is not practically possible manually.
But this is now possible. Let us find out how to do it using Robocopy, a Windows tool an an alternative software, Copywhiz.

Steps to filter files based on their last access
The Robocopy command Robocopy Source [Destination] /MAXLAD:n[YYYYMMDD] is used to depict the maximum last access date which means it excludes files unused since ‘n’. Here, n is either days or the exact date whichever you find convenient.
For example: While copying files from the folder “projects” to the folder “backup”, if you want to exclude files that have not been accessed since 10 JAN 2018:
Robocopy c:\projects c:\backup /maxlad:20180110
Similarly, you can even exclude frequently used files from being copied. This is for when you have a large number of unused files that you need to keep aside as a mere record.
Again, Robocopy can do this using the command Robocopy source [destination] /minlad:n[YYYYMMDD], which depicts the minimum last access days which means it will exclude files used since the specified day/date.
For example: If you want to exclude files accessed since 10 JAN 2018:
Robocopy /minlad: 
will be used.
Even though Robocopy does it for you, these commands are not easy to use. System administrators use it. But, Robocopy is not straightforward for ordinary users.
I will now show you an easier and faster method.
