Question

I am trying to create a little script to convert video on windows using the ‘send to’ menu.
For this I want to create a new file name from the one in input.
But I fail to concatenate strings.

Following the syntax found here, I wrote this piece of code:

@echo Input:
@echo %1
set "outputfile=%1%.MP4"
@echo %outputfile%

But I have an issue with the quotes in the outputfile:

Input:
"D:\this is a test\MVI_7754.AVI"

D:\this is a test>set "outputfile="D:\this is a test\MVI_7754.AVI".MP4"
"D:\this is a test\MVI_7754.AVI".MP4

I would expect the extension inside the quotes not outside!

Could someone tell me how I can concatenate the file name and the extension?
Thanks!

Answer 1

@echo Input:
@echo %1
set outputfile="%~1.MP4"
@echo %outputfile%

to remove previous extension
use

set outputfile="%~n1.MP4"

if you don’t use path names or

set outputfile="%~dpn1.MP4"

(name will be converted to full path)
