Backs up (saves) modified dates (timestamps) for all files including those in subfolders in a directory with the ability to later restore them from the saved state, might be useful for cloud backup software and services which don't support restoring file timestamps when getting your files back

Get executable files from the Releases section

Usage:
backup-file-timestamps.exe - uses current directory (or the one dragged onto it) to go and save timestamps
backup-file-timestamps.exe -save "C:\my folder" - save modified time dates inside C:\my folder and its subfolders
backup-file-timestamps.exe -restore "C:\my folder" - restores modified time dates for all files inside C:\my folder and its subfolders

Console-less usage (GUI):

Navigate to shell:sendto (enter into explorer's address bar or the Run command)
or

and place two files executable files there - backup-file-timestamps.exe and restore file timestamps.bat (or shortcuts to them, doesn't matter)

now after that you can simply click "send to" in context menu on any folder
