So, seems like you've tried almost all the fixes available on the web. This is the last thing you need to give a try and I am hopeful that it will work for you.
Download and install 7zip using this link: Download 7zip.
Now, Go to the folder where those files are. Select all of them using Ctrl+A
. After selection, they will look like this:
(see, everything turned light blue.)
While they are selected, right click on the selection and a menu will appear. In that menu, go to 7-zip>Add to "[filename].zip"
and click on it:
(here the filename in my case is 'scanned.zip', it can be anything else in your case depending on the folder name)
After that, you will see a screen like this:
After completion of this process, you will see that a new file has been added to that particular folder where your files are, you can see here:
(notice the icon of that particular file, it seems like it's been zipped; right?)
Now copy that [filename].zip (in my case; in your case: .zip at the end might not appear) file to that folder where you wanted those files to copy but couldn't due to the error. Once you are there, right click on that file (here, scanned.zip). A menu will appear. On that menu go to 7-zip>Extract here
:
That's it. It will extract all the files right inside the folder where you have stored the scanned.zip file.
I hope this works for you. This is the most straight forward solution I can think of for you.
Have a good day. Tell me how it does :)
P.S.: This might take some extra time (not much).
