![]() subfolders within subfolders within subfolders. Change file extensions for files that have been processed by other Actions. Windows automatically selects the filename so that anything you type will replace the existing name. This will also work to any folder tree depth. Click the file to select it, then click once more. Now we can see every file in every subfolder is renamed in one operation. The wildcards work here the same as with any other command that filters file names. Rename_files_recursively ( r"C:\\Users\\shedloadofcode\\Documents\\TestFolder" ) The sourceMask works as a filter to determine which files are renamed. Or you can use many of the excellent mass rename tools available on the net. Since you're not appending in front or behind, you might have to fiddle with each string to split it into filename and extension before renaming it to filename append extension. ![]() rename (file_path, new_name ) continueĬount = 1 print ( f" " ) if _name_ = "_main_" : Then I'd use that file as input to the batch-loops mentioned in the article above. 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.

From a batch file, you need to double all of the symbols like this: for /f 'tokens1 delims.' i in ('dir /b yyy.') do ren 'i.j' 'ij.zzz' Make sure you run this command from the folder where all of the yyy.xxxxxx files reside. 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. If you don't want to select every file, you can hold the Shift. ![]() The name of the last file will become highlighted. 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. Open File Explorer and navigate to the folder with the files you want to rename. To rename multiple files from File Explorer, select all the files you wish to rename, then press the F2 key. This is a situation I found myself in recently, a seemingly simple request to help rename a few hundred files in a folder. 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. ![]()
