Find and replace bunch of filenames

edit: for purpose of unity terrains, you don't need to rename from .r16. just switch file search dropdown to all files and you can import the .r16 and it will work.

Windows explorer doesn't have any find and replace function. I have hundreds of .r16 files need to change to .raw.

I think I can use this code here in powershell:
Dir | Rename-Item -NewName {$_.name -replace "Mustang","Appaloosa"}

but I don't know how to implement it for my purpose. In my case, i need to find "r16" and replace with "raw"

Otherwise, you guys know some tools I could use, either in windows or maybe inside unity?

Thank you!

 

C# and the System.IO namespace can do this. If you need something quick and dirty you can just run it from a Unity script.

 

I think this is one I've used in the past, but as with any free software be careful what you install. The UI is cluttered as all heck, but just enable the one bit you need and it's ok.

 

Try use TotalCommander for such things. In past was called Windowscomander, but name changed years ago, because of naming conflict with M$, Is free to use for none commercial applications.

 

You can use C#, like suggested by boredmo... I mean Kiwasi, or you could cook up a python script.

If you're familiar with unix/linux, you can install mingw or msys, and use unix tools for that.

Additionally, if you don't want to script, you can use "orthodox file manager" like FarManager, TotalCommander and so on. In FAR, renaming a few million of files is a matter of few keypresses. You just select target folder, and specify that you want *.raw as a filename. It'll rename it by default.

Far Manager is available for free under opensource license.

Using FAR will be probably fastest.

 

a simple command prompt should do the trick though. ren *.r16 *.raw

 

Indeed.^
If you need a little more complexity, you just write shell script. If you need complexity you can use Ruby/Python/AS and write some to run in the shell. If is something you use a lot, save the script and stick a shortcut to it in your bash profile.

 

I tried using command but I couldn't figure out how to navigate to the right folder. By default command is starting from my SSD, but I was needing to get at a folder on harddrive. Just typing or copy/paste in the directory wasn't working. Scripting makes no sense to me. Anyway, I did the same thing but through powershell, because you can open powershell directly from explorer and it goes to the right place. Here's what I did:

I wouldn't have known to even look if not for advices here. Thanks everybody! Save me a lot of trouble.

 

you type a letter of desired hard drive. "c:"
Then navigate where you need using cd command. "cd .." goes up. "cd <foldername>" goes down folder. "dir" lists contents of current folder.

 

How do I get rid of this default directory?

 

Examples here: https://www.howtogeek.com/111859/ho...s-in-windows-4-ways-to-rename-multiple-files/

Scroll down to "Since the ren command can address extensions, you can also use it to change the extensions of multiple files at once. Say, for example, you had a selection of .txt files that you wanted to turn into .html files. You ..."

 

Wrong syntax.
Command line accepts "command" followed by parameters separated by spaces. If parameters hold spaces, they can be enclosed into quotes.
There's no command "c", however you can type "c:" (with semicolon), which will be a different thing.

In your example, you're already on drive C, so you don't need to type letters.

Instead you type "cd .."(followed by enter) to go up, "cd <foldername>" to go down, "dir"(followed by enter) to list contents and so on.

That's just basics.
