Hi everybody i would like to ask how i can remove a mistakenly added second file extension using a batch script.
E.g. "test.aac.m4a" -> "test.m4a"
So the last extension is the right one which i want to have.
But this is ONLY the case for
.aac.m4a
-> .m4a
and
.m4a.aac
-> .aac
I know some batch scripting but
ren *.aac.m4a *.m4a
Won't work :(
Another thing worth mentioning would be that these double extensions come from my music software MusicBee.
I use mp4box on m4a files to extract the raw aac stream from the m4a container so i can edit it in other software.
Currently the syntax is:
mp4box.exe -raw 1 "<URL>" -out "<URL>".aac
The "<URL>" is the variable MusicBee will replace with the file url.
But this will add the .aac extension after the .m4a and i have no idea how to replace it instead. (and again when i repack the files ".aac -> .aac.m4a")
As far as i know MusicBee just replaces the variables and launches the batch code when activated so i think other batch code will work too.
Is it possible to prevent this double extension from even developing?
As always ANY help is apreciated!!
Thanks, Daniel
In preventing the double extension from developing I'm guessing you're not appending the file extension accordingly in the right way, I am however not familiar at all with Music Bee.
As for creating the right batch files that do what you want, I've used Advanced File Renamer in the past for all sorts of renaming patterns such as your case. It's freeware too! The program has a fairly advanced feature that allows users to write custom scripts in JavaScript user guide here. And can even generate batch scripts that do special renaming (as you've noted in the comments) for your specific use case.
For the other less advanced users the program has a GUI that makes it easy to do batch renames.
Best of all, if you're like me that avoids third party software installs just to do one thing as much as possible, the program has a portable mode that won't hook itself into your system, which is always good.
Read the manuals and guides there for more information. My answer might sound a little too much like advertising for it, but that's only because it's helped me so much in renaming my music a long time ago.
Here's a screenshot by the OP, RapidFireArts that shows how OP used the software to remove the second file extension.
It ought to be possible, but I have no idea how to work with your software to prevent the double extensions from occurring in the first place. But it is fairly easy to strip off the unwanted middle "extension".
If you know for a fact that none of your .m4a or .aac files are supposed to have multiple dots, then you could simply do the following:
ren *.m4a ???????????????????????????????????????????.m4a
ren *.aac ???????????????????????????????????????????.aac
Just make sure you have enough ? wildcards to match the longest name in your folder. See How does the Windows RENAME command interpret wildcards? for an explanation of why this solution works.
But sometimes file names legitimately have additional dots prior to the actual extension. If this is your case, then the following batch script will remove only the unwanted .m4a and .aac middle "extensions"
#echo off
for /f "eol=: delims=" %%A in ('dir /b /a-d *.m4a.aac *.aac.m4a') do (
for %%B in ("%%A") do ren "%%A" "%%~nB%%~xA"
)
Another option is to use my JREN.BAT regular expression file renaming utility. JREN.BAT is a hybrid JScript/batch script that runs natively on any Windows machine from XP onward. Ideally, the script should be placed within a folder that is included within your PATH. I like to use c:\utils for all of my non-standard utilities.
Once you have JREN.BAT, then all you would need would be
call jren "\.(m4a|aac)(?=\.(m4a|aac)$)" ""
Provided you understand regular expressions, and you take the time to read the built-in JREN help, then there are many wondrous things you can do with the utility. The help is accessed by issuing jren /? from the command line. You might want to use jren /?|more if you have not configured your console window to have a large buffer that enables scrolling to see prior output.
I use File Renamer Basic.

I have many many pdf files in a directory that I need to convert from pdf to png. Currently, I am using the ImageMagick command:
magick mogrify -format png *.pdf
Because, there are so many files, I would like to use ghostscript directly because there are several sources that suggest that I could achieve a 75% reduction in processing time by doing this.
However, I am having trouble finding a clean dos command example to accomplish the same thing as the ImageMagick command above. I believe I need to execute the gswin64c.exe module but I am unsure how to do this to accomplish what I need to get done. Can someone provide me with a clean example of the ghostscript that accomplishes what I'm doing in ImageMagick?
After much digging, what I discovered was that ghostscript does not really have a wildcard that would allow reference to all files of a certain pattern (like ImageMagick does). To convert all files in a directory that are pdf's to png's, a dos script like the following could be used:
for %%x in (*) do gswin64c.exe -sDEVICE=png16m -dBATCH -dNOPAUSE -dQUIET -
SOutputFile="%%~nx.png" %%~nx.pdf
This can also be run from the command line by simply using single percentage signs (%) instead of the double percentage signs in the script above.
The terms are as follows:
gswin64c.exe: This is the dos command version of GhostScript. It should be used as opposed to gswin64.exe which will open a GhostScript window.
-sDEVICE=png16m This indicates the form of the output file. Is this case png.
-dBATCH -dNOPAUSE. These are GhostScript options and when employed will allow for continuous operation of the script (without them, the program will pause after each file converted).
-dQUIET - This suppresses notifications that display on stdout after each processed file.
SOutputFile="%%~nx.png" %%~nx.pdf This indicates the pattern for the input files and the output files. x is the loop variable. The % sign is used as a wild card. ~nx is a Dos convention which truncates the extension of an echoed file name.
I have a problem where i need to batch convert 50,000 tiff's into 50,000 txt files respectively. I am aware of abbyy finereader and some other pieces of software that may be able to do this, but a free solution would be best. I have been researching tesseract as well. Is anyone aware of any script or program that uses tesseract to do this automatically with a good quality output??
Thanks in advance
For a free solution with Tesseract, here's a straightforward command line batch file. Change the variable contents and/or create folders as necessary:
:Start
#Echo off
Set _SourcePath=C:\tifs\*.tif
Set _OutputPath=C:\txts\
Set _Tesseract="C:\Program Files (x86)\Tesseract-OCR\tesseract.exe"
:Convert
For %%A in (%_SourcePath%) Do Echo Converting %%A...&%_Tesseract% %%A %_OutputPath%%%~nA
:End
Set "_SourcePath="
Set "_OutputPath="
Set "_Tesseract="
In my opinion, I think Tesseract is going to give you the best results, whether you're looking at free solutions or not.
If you figure out how to convert one file, and then you post back the command you use, it will be easy to hack a batch script together to process multiple files.
Take a look at VietOCR, a Java/.NET frontend for Tesseract; its function seems to suit your need.
I have a Windows batch file which has an instruction to execute an EXE file in a location whose path contains accented characters. Following are the contents of the batch file.
#echo off
C:\español\jre\bin\java.exe -version
C:\español\jre\bin\java.exe - This path exists and is proper. I can run this command directly on cmd.exe. But when I run the command from a bat/cmd file it fails saying "The system cannot find the path specified"
One way to fix this is by setting code page to 1252 (that works for me). But I'm afraid we'd have to set code pages for any non-English locale and figuring out which code page to use is pretty difficult.
Is there an alternative approach to fix this problem? Maybe a command-line option or something else?
Another way of doing this, in Windows, is by using wordpad.exe:
Run wordpad.exe
Write your script as you usually do, with accents
Choose Save as > Other formats
Choose to save it as Text document MS-DOS (*.txt)
Change the file extension from .txt to .bat
I had the same problem, and this answer solved it. Basically you have to wrap your script with a bunch of commands to change your terminal codepage, and then to restore it.
#echo off
for /f "tokens=2 delims=:." %%x in ('chcp') do set cp=%%x
chcp 1252>nul
:: your stuff here ::
chcp %cp%>nul
Worked like a charm!
I'm using Notepad++ and it has an option to change "character sets", OEM-US did the trick. ;)
Since you have #echo off you can't see what your batch is sending to the command prompt. Reproducing your problem with that off it seems like the ñ character gets misinterpreted since the output I see is:
C:\espa±ol\jre\bin\java -version
The system cannot find the path specified.
I was able to get it to work by echoing the command into the batch file from the command prompt, i.e.
echo C:\español\jre\bin\java.exe -version>>test.bat
This seems to translate the character into whatever the command prompt is looking for, though I've only tested it with English locale set so I don't know if it'll work in all situations for you. Also, if you open the batch in a text editor like notepad it looks wrong (C:\espa¤ol\jre\bin\java.exe)
Use Alt + 0164 for ¤ instead of Alt + 164 ñ in a batch file... It will look odd, but your script should run.
You can use Visual Studio Code and it will let you select the encoding you want to use. Lower right corner, you select the encoding and will display option "save with encoding". Select DOS and will save the accented chars.
I also had the same problem. I was trying to create a simple XCOPY batch file to copy a spreadsheet from one folder to another. Its name had the "é" character in it, and it refused to copy.
Even trying to use Katalin's and Metalcoder's suggestions didn't work on my neolithic Windows XP machine. Then I suddenly thought: Why not keep things as simple as possible (as I am myself extremely simple-minded when it comes to computers) and just substitute, in the batch file code, "é" with the wildcard character "?".
And guess what? It worked!
What are batch files useful for? They just seem to be used to make viruses and other things...but it seems like shell scripting to me.
Whats the uses for batch files?
From Batch file article at Wikipedia:
Batch files are useful for running a
sequence of executables automatically
and are often used by system
administrators to automate tedious
processes. Unix-like operating
systems (such as Linux) have a similar
type of file called a shell script.
A simple example:
for /f "tokens=* delims=" %%i in ('dir /s /b /a:d *svn') do ( rd /s /q "%%i")
If you save the above line in a file called ClearSVNFolders.bat and after that execute a double click you'll delete every folder named svn that resides inside a root path...
You automated the whole process. You could easily spend hours doing the above task if you had a deep root directory, that is, one containing thousands of folders. :)
Batch files are the Windows equivalent of a Unix shell script. So you can use them to automate things.
You could use them for shell scripting. :-P
Of course, they kind of suck at that, compared to bash (or perl/python/tcl). But if you're on Windows, it's a one-horse race unless you want to install cygwin or msys and battle with Unix/Windows incompatibilities.
Batch Files are extremely useful. They are super easy to learn as well. you can make them do things on startup like say that a program wants to open itself and wont close even from taskman.exe you can force it to shutoff without warning.
or you could make games and ineractive things like i like to do.
i have a Messenger that i made with fully customizable colors and accounts with account management and servers.
But you probably dont trust me enough for you to download it.
But yea they are pretty useful.
Batch file is "a computer file containing a list of instructions to be carried out in turn."
We have been studying since childhood that computer is a dummy machine and this is a method of instructing a dummy machine.
For example :-
If you want to instruct the system to create a folder with random name then type ,
#echo off
md %random%
Creating Batch files enables you to execute several line of CMD commands in a single file.
For example :-
#echo off
md %random%
tasklist
Pause
The entire purpose of a Batch script is to execute several DOS commands in sequence:
echo Hello!
set var=7
echo I just made var=%var%!
pause
It was invented in MS-DOS for user simplicity to execute things they did all the time, the most notable thing being "AUTOEXEC.BAT" which started once the command interpreter started, people would add things like:
echo Welcome to my computer!
or
cd C:\Games\
To make it quicker to access their games or whatever they needed.
I have a batch file I've created which uses xcopy to copy a dir, and child dirs, and merge them into one file. (ie. all my modulised development css stylesheets merged into one production stylesheet).
Everything is good, apart from the fact that when I reference the excludelist.txt, it only excludes the first line, and not the subsequent files I want excluded.
Anyone fancy a crack at this? You'd be most helpful.
Here's the code:
XCOPY C:\xampp\htdocs\PROJECT\css\*.* C:\temp /S /I /Y /EXCLUDE:C:\xampp\htdocs\PROJECT\exclude.txt
...and inside my exclude.txt is...
1.css
2.css
3.css
4.css
5.css
///// I know the code works (to an extent) because it is infact excluding file 1.css -- just not the ones below it. Am I right to put each exclusion on a new line?
I use the following,
xcopy "C:\users\dad\*.*" dad /s /d <yesnoyesno /EXCLUDE:excluexclu 1>cop.txt 2>err.txt
as somewhere on the web I saw a note to the effect that the /Y switch could not be used directly with an exclude file.
What I wanted to point out here, was the useful output files 1 & 2, which detail the success & failure issues.
Mine shows only success.
The short answer: Create a new text file, type the entries and save the file.
The longer explanation: I ran into this very issue on a Windows 2008 server today. I tried all kinds of things to get it to work. Forced notepad to save the file as ANSI, Unicode and UTF-8 but all of them had the same problem. Finally I started thinking about the fact that I put the file on the server via FTP and it's quite likely that FTP tweaked the file format. I created a new text file on the server, typed all the same entries in the new file and now it works.
I had a similar problem. I was trying to exclude all files with a certain extension in the root folder and any sub-folders and it didn't work. The reason was I was putting *.pdb instead of just .pdb. The newline/carriage return thing was a total red herring for me.
So my file just looked like:
.pdb
.obj
.vb
.cs
You seem to be using xcopy correctly - each exclusion file (or match depending on wildcards) should be on a new line within the file. So far I've been unable to reproduce the behaviour you're experiencing.
Is the exclude.txt listing you've given above a test file, or are they the actual css names?
What are the names of the other files that your batch file is supposed to copy?
Edit:
That the xcopy is failing to exclude further files after a single match is giving me most pause. I thought it might be to do with the type of carriage-return that was used in the exclude file, but xcopy handles unix-style carriage-returns just fine.
Can you re-verify that the correct exclude file is being used?
Try forcing it to save with ANSI encoding on your text editor.
I was having a similar issue and that did it.
