![]() subfolders within subfolders within subfolders. This will also work to any folder tree depth. Now we can see every file in every subfolder is renamed in one operation. Rename_files_recursively ( r"C:\\Users\\shedloadofcode\\Documents\\TestFolder" ) rename (file_path, new_name ) continueĬount += 1 print ( f" " ) if _name_ = "_main_" : join (path, prefix + postfix + extension ) splitext (filename ) for i, term in enumerate (search_terms ) : if term in name : Search_terms = Ĭount = 0 for filename in os. nxA: Expands the value stored in parameter A to a filename and extension. Line 3: renames the MDX file to the parent directory name. Line 2: Loop through the parent directory for the MDX file. The solution: Get the filename.ext with nxF (see for / to read more about those modifiers) and change the ren syntax accordingly: the full path (source) would then be 'F' and the. Line 1: Loops through all the MDX files recursively and set the value to a parameter. Your filename is a full path when you use /R. Syntax: REN drive: pathfilename1 filename2. To trim the identifier at the beginning of the file name we’ll use string slicing. The reason: ren destination is the filename only - no path. For example, if the file name includes X then replace with Y. As you can see it isn’t a straight up find and replace job, we will need some logic to match a search term to a replacement. The files names on the left needed to look like the file names on the right (this is a small sample but there were hundreds of files). The problem given was that during an automation process hundreds of files had been produced but using the wrong names. This called for a custom script to help out a fellow engineer. However, not all of the renaming followed a set pattern! Nor did it follow any real pattern at all, so using regex probably wasn’t going to help. This is a situation I found myself in recently, a seemingly simple request to help rename a few hundred files in a folder. 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 (.Although there are many tutorials on renaming files with Python, most don’t go into how to create flexible logic to tailor that batch file rename job to your needs. 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. FOR executes for each file the executable D:\Test. The name of each found file is assigned with full path to case-sensitive loop variable I. The command FOR searches recursive in directory D:\Test and all subdirectories for files matching the wildcard pattern. If an argument is given, then that value is used as the root folder. for /R 'D:\Test' I in (.bin) do D:\Test\script.exe -i 'I'. 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 first step to batch recursive renaming is to select the folder which you wish to rename recursively, this is done by simply selecting the folder in Quick. 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.
