Q: Kuinka voin nimetä tiedostotunnisteet uudelleen erän Windowsissa?
A: Changing a single file extension in Windows is simple. Just highlight the tiedostonimi in Windows Explorer and type a new extension after the dot. While this method works fine for a small number of files, manually editing a large number of filenames can take a long time. Fortunately, you can speed up the process through automation by following the steps below.
Files in a Single Folder
Below is an example folder with several . TXT files that need to be changed to .XML tiedostoja.
1. In order to batch rename file extensions, you will first need to open the Windows Command Prompt. To do this, choose.
You can also type "cmd" and press Enter in the Windows Start Menu text field.
2. Navigate to the directory containing the files to rename using the "cd" command ("cd" stands for "change directory"). For example, you would type "cd Desktop\XML Docs" to navigate to a folder named "XML Docs" on the Windows desktop.
3. Type the following command, which will rename all *.txt files in the current folder to *.xml files:
ren *.txt *.xml
4. The files are all renamed from *.txt to *.xml:
HUOMAUTUS: If your files have different extensions, or they do not have an extension at all and you would like to add an extension to them, you can use this command instead:
ren * *.xml
Files in Subfolders
Renaming files in subfolders (or alihakemistot) is a more complex task that requires additional syntaksi. The following command uses a loop that iteroi through subfolders (one level deep) and changes all file extensions from *.txt to *.xml:
for /d %x in (*) do pushd %x & ren *.txt *.xml & popd
Voit korvata * .txt että *.xml with any other extensions in the commands above. Also, you can replace * .txt (the first variable) with just * if you want to rename all extensions for all files.
HUOMAUTUS: Make sure you type the commands above correctly, as you may not be able to undo the renaming process. If you want to be extra safe, you can copy the files to a new folder so that you have a backup of the files before you run the rename command. Once the renaming process completes successfully, you can delete the extra copy of the files.
