E2B2, I have this one (v7) and it works fine...

E2B2, apparently only the Lite edition is free... the full version is paid.

To be clear of what I need:

"Macbeth Camera1 John.mp4"
"Macbeth Camera1.mp4"

"Macbeth Camera2 Mary.mp4"
"Macbeth Camera2.mp4"

"Macbeth Camera3 Nick.mp4"
"Macbeth Camera3.mp4"

etc., etc..

Thanks,
Nick...

Nick, I would imagine you would Add replace rules for each specific string ending and include the file extension thus
Add find text " John.mp4" replace text ".mp4"
Add find text " Mary.mp4" replace text ".mp4" and so on... really this is not the best way to do that as you are creating find and replace rules for practically each file which is soo inefficient you might as well just rename files manually as it will involve less steps!

Nick, With a BIG disclaimer that I cannot code, the closest I could come up with is using PowerToys PowerRename with Find: (\w+\s)(\w+\s).*
Replace: $1$2.mp4

and Use Regular Expressions checked. That however does leave a space after Camera#. It's admittedly a kludge but that could be removed with a 2nd rename using:
Find: .{5}$
Replace: .mp4

Hi Nick!
If the list of names is limited then you add them all separately under "Replace strings".
Simply add ' Nick' (make sure to include the leading blank) to "Find Text" field, and just leave the "Replace To" field as blank.
Repeat with every name.
Verify the results in the preview table.

Nick,

I'd try using the replace string if you have multiple files with the same name. In the "find text" section, enter in " John" (there is a space just before John) and in the "replace to" section, leave it completely blank. If the software is designed properly, this should take the space and name and replace it with nothing, in theory removing it from the file name.

I'd probably create a couple text files with similar names like you want to rename and test this out on them before running it on your live files.

Other batch renaming software I've used in the past has had the option of deleting X-number of characters from the beginning or end of a file name, though in the provided screenshots on the software above, I don't see that as an option.

Nick,

Open a text editor like Notepad.
Copy and paste the following script into the editor:
batch

@echo off
setlocal enabledelayedexpansion

REM Change to the directory containing the files
cd /d "C:\path\to\your\files"

for %%f in (*.mp4) do (
set "filename=%%~nf"
set "extension=%%~xf"

REM Remove the last space and name part before the extension
for /f "tokens=1,* delims= " %%a in ("!filename!") do (
set "newname=%%a!extension!"
ren "%%f" "!newname!"
)
)

endlocal

Replace "C:\path\to\your\files" with the actual path to your directory containing the files.
Save the file with a .bat extension, for example, rename_files.bat.
Double-click the .bat file to run it.

Nick,

Batch file corrected

@echo off
setlocal enabledelayedexpansion

REM Change to the directory containing the files
cd /d "C:\path\to\your\files"

for %%f in (*.mp4) do (
set "filename=%%~nf"
set "extension=%%~xf"

REM Remove the last space and name part before the extension
for /f "tokens=1* delims= " %%a in ("!filename!") do (
set "base=%%a"
)

ren "%%f" "!base!!extension!"
)

endlocal

TK, Thanks, but that doesn't work..

mike, Thanks - but the idea is to use this program to do it.

twm, I tried that with both the ' quote as well as the double quotes _ as in "
Neither worked.
Thanks for the thought (ˆ◡ˆ)

Denis, I don't see a batch editor in this program ??

FeMaster, Tried this too - no luck with either type of quotes

Hi Nick,

You can use “{N*-*} File Name” and enter the starting and end character position of the range you want to modify.

e.g.
"Macbeth Camera1" "Macbeth Camera2" "Macbeth Camera3"
there are 15 characters (including space), so we need to type {N1-15} in the "Filename Patterns" panel.

Ferdinand, I am testing 'this' program not others.
