Saving newer documents

I guess you need something to compare folder content.

E.g.
WINMERGE

WinMerge is an Open Source comparing and merging tool for Windows. WinMerge can
compare both folders and files, presenting differences in a visual text format
that is easy to understand and handle. WinMerge can be used as an external
differencing/merging tool or as a standalone application.

WinMerge has many helpful supporting features to make comparing, synchronising,
and merging as easy and useful as possible. Several programming languages and
other file formats are syntax-highlighted.

The latest WinMerge version and WinMerge information is available at
WinMerge.

On previous versions of Windows, if I tried to save documents from, say a thumb drive to my hard drive and the names of the docs were identical, I would be asked if I wanted to save the newer version or not.... I don't want lose the recent work I've done at either place but can't find the "newer version" option...

Welcome to TenForums @hotdog

If you use File Explorer to copy files from one location to another all files that don't exist in the destination will be copied without comment. If it finds files are already there with the same names, then it will ask you what you want to do about it. Click on 'Let me decide for each file' for more control, where it will show you all the files with differing dates or sizes (the newest/largest with its date/size in bold). Untick 'Skip files with the same name and date' if you want complete control.
