Remove extension from multiple files in multiple sub directories

Dear All,

I want to remove the extension from all the available files in all the sub folders in a Main folder.

Example : Below is the folder structure.

MainDirectory
|
|---> SubDirectory1/ abc1.config.txt / abc2.config.txt /  abc3.config.txt /
|
|---> SubDirectory2/ abc1.config.txt / abc2.config.txt /  abc3.config.txt /
|
|---> SubDirectory3/ abc1.config.txt / abc2.config.txt /  abc3.config.txt /

So, I want ".txt" extension to be removed from all the files in all the sub directories programmatically in c#, so that I will be having only config files at the end.

Please suggest or provide some piece of c# code.

Thanks in advance,

What I have tried:

I have tried Path.ChangeExtension which actually replaces the extension with null, but it does not apply for physical file. I mean, it just gives the value to the user in logical way.

Do you need to perform this change recursively ? i.e., are there arbitrary levels of nesting ?

Solution 1

Once you have changed the extension you need to use File.Move Method (String, String) (System.IO)[^] to rename it.

Solution 3

You can call 'Move on the File, while removing the ".txt" extension, which will result in the extension being ".config:"

C#

string path = @"C:\Users\Whoever\Desktop\SubDirectory1\abc1.txt.config";

string newpath = Path.ChangeExtension(path, "");
File.Move(path, newpath);

While this "works," the need to manipulate file extensions in this way makes me wonder if there isn't a simpler way to do whatever it is you are doing here.

Solution 2

Try:

C#

string[] files = Directory.GetFiles(@"D:\Temp\", "*.txt", SearchOption.AllDirectories);
foreach (string file in files)
    {
    File.Move(file, file.Substring(0, file.Length - 4));
    }
