Let me show you, please ...
I'm doing a "Compare by file size"

My 3 Subdirectory (the focus of my working directories) are:
Also please note that my view settings for the compare window are ONLY the "EQUAL" files view:

Next I take note of the count in both the bottom "Equal" indicator

And the "Overview window"

I note in the overview window that the files are "0" (Zero) bytes
Then I take note of the total of 2 (two) files in 2 (two) separate directories, which concludes that there is one zero byte file in the left-hand Relative File List.
/Samsung_One_TerraByte/USB/SANDISKBACKUP/Backup/WINDOWS/Debug/
filename: oakley.log.sav
•I highlight the above file
•right-click my mouse on the blue high-lit file
•the menu pops-up
•I select from the command drop-down list "Browse directory"
this new window pops open to show/confirm my selection(s) as a valid 0 byte file:

with the right-side list Relative File List, I repeat the same above steps on the separate file also named:
/Samsung_One_TerraByte/USB/FromSanDisk/Backup/WINDOWS/Debug/
filename: oakley.log.sav

Now, before I delete the files, this is my full window view as a reference screen saved to show "Before"

I again, select one of the blue highlighted files in the list, I then type "Ctrl + Delete" (without the +) on my keyboard and a new popup window Warns me of my action:

I click the "Delete" button.

Should the bottom "Equal" count button and the "Overview" "Items" column show a count of "1977" ?
I deleted these 2 files, so if my college math is incorrect 1979 - 2 = 1977
