![]() The new name in cell AB must be the name that replaces the old name in cell A2. I have the full path containing the old name in an excel column matched to the full path containing the new name in the adjacent excel column. Parent folder is the lowest common folder in the shared hierarchy of all files i need to change I also can use the standard version of the app Beyond Compare.Ĭ:\Users\joe\Desktop\Parentfolder\child folder\grandchildfolder#NA#1329001.00#1329001.00\file1.pdfĬ:\Users\joe\Desktop\Parentfolder\child folder\grandchildfolder#NA#1329001.00#1329001.00\company xyz.pdf I cannot use a third party application I can only use command prompt or powershell or whatever comes with Windows 2010. I need the new name to be a specific unique name. I need to batch or mass rename 76k+ file names in multiple folders and subfolders in a directory. forfiles /M *.jpg /C "cmd /c rename - pic.jpg\"" So that forfiles does not misinterpret this doublequotes, you need to escape them with ‘\’įor example to add ” – pic.jpg” to each of the jpg files, the command would be as below. If the new name you want to assign to the files has white space within it, it can be done by adding double quotes around the file name. forfiles /S /M *.jpg /C "cmd /c rename " Handling names with white spaces Similarly, we can add a number to a file name. Here we try to add ‘photo’ to every jpg file in the current folder and subfolders. ![]() If you want to add any prefix to file names, it can be done as in the below example. forfiles /S /M *.ext /C "cmd /c rename you want a batch file script, it can be downloaded from the below link:īatch file script for renaming file extensions in bulk Add prefix to file names in batch The below command would remove extension for the specified file types. forfiles /S /M *.ext1 /C "cmd /c rename example, if you want to rename all xml files to txt files, the command would be as below forfiles /S /M *.xml /C "cmd /c rename Remove file extensions in batch The command can be put in a batch script that accepts an optional root folder as an argument (process current directory if no value given): offįor /r %1 %%F in (.If you want to rename files from one extension to another, recursively in all sub folders, then you can use the below command. And the /FX "%~nxF_* option excludes files that already begin with the name of the parent folder, followed by an underscore. The /P "%F" option specifies the root folder. The first two JREN arguments are the find/replace strings - The search matches the beginning of the file name, and the replace simply insert the parent folder name (with a trailing underscore). The following simple command will process the tree rooted at the current directory: for /r %F in (.) do jren "^" "%~nxF_" /p "%F" /fx "%~nxF_*" No 3rd party exe files are needed.įull documentation is embedded within the utility - accessed via jren /?, or jren /? if you want paged output. It is pure script (hybrid batch/JScript) that runs natively on any Windows machine from XP onward. The code is simpler if you use my JREN.BAT regular expression renaming utility. If an argument is given, then that value is used as the root folder. If no argument is given, then the script processes starting at the current directory. The command can be put in a script, and then the root folder to process can be passed in as an argument. It will process the tree rooted at the current directory. Putting it all together, the following long one liner can be used directly on the command line. The %%~nxD returns just the folder name and extension of the parent folder. The EOL and DELIMS options are used to make sure that the full name of every file is preserved. The results of the piped command can be iterated with FOR /F. ![]() But you don't want to rename files that aready begin with the parent folder name, so that can be piped to FINDSTR to exclude the already renamed files. The DIR /B /A-D "folderPath" command can list all files within a folder. The FOR /R command can iterate the folder paths of all folders within a root tree. "fileName.ext" -> "parentFolderName_fileName.ext" That is not a reasonable expectation unless there are unusual circumstances.īut it is possible to insert the name of the parent folder in front of every file - something like You can only accomplish your stated goal if each folder never has more than one file of any given type.
