I get a file name warning for some folder called "C:\Program" ?

Could you, with the Snipping Tool, make a "snip" of that error msg for me?
Make a snapshot (Snip)
WIN | type SNIP | ENTER |
Drag the cursor around the area you want to snip. |
File | Save as | select save location and name | Save

WIN=key with the Microsoft logo on top.

Go To an Elevated Command Prompt


Elevated command prompt = Run CMD.EXE as administrator

WIN | type CMD.EXE | do not hit Enter |
in the PROGRAMS list, right-click on CMD.EXE |
choose "Run as administrator" |
Click on the YES button (if such appears)

WIN key = key with Microsoft log on top

for the guru:
WIN | type CMD.EXE | CTRL+SHIFT+ENTER key combo | ALT+Y keycombo

Why that you ask?

I would like for you to go to an elevated command prompt.

Once there,
enter
cd /d %systemdrive%\
and hit the enter key

now enter
attrib | clip
and hit enter

That put the output of the command into the clipboard.
Now enter
EXIT
and hit enter
that got you out of the command shell.

Interesting. c:\Program is not a system or hidden file.
You should be able to delete the file by going back to an elevated command prompt and typing
cd /d %systemdrive%\
del .\Program\* /s

Notice the "dot" before the slash

after doing the delete then do a dir command and see if \program is still there

what is that wierd C:\.BridgeLabelsAndRatings

You should be able to delete the file by going back to an elevated command prompt and typing
cd /d %systemdrive%\
del .\Program\* /s

That MUST be typed precisely as it appears.
There is a trick you can use.
Use CTRL + C to copy those two lines then go to the elevated command prompt.
Now, you use RIGHT-CLICK with your mouse to paste.
Hit the Enter key so that the 2nd command gets executed.

Ok, I did exactly as you instructed, but when I hit Enter I get: "The directory name is invalid.

I did a quick search for that C:\.BridgeLabelsAndRatings and I found it's associated with Adobe Bridge. The .bridgelabelandratings files contain metadata.

I did make one mistake, although doesn't explain what you saw.

the two commands should read:
CD /D %SYSTEMDRIVE%\
RD .\PROGRAM /S

Answer the prompt with yes.

I created a \Program folder with files inside and carried out the commands. Here is what happens:
