    Rename multiple files in one directory

    Is it possible to rename all the files in a folder with a simple program using vb.NET

    Lets say there is a folder containing the files, files are vary every time loaded:

    A.258551.txt
    b_466464.txt
    c-548754354.txt

    Will it be possible to rename these files in one operation,as below:

    A.txt
    B.txt
    C.txt

    Any code please

    Re: Rename multiple files in one directory

    I can't think of a single command that would do what you want.

    But it's trivial to read the directory (all the file names in the directory) into an array using the GetFiles() function

    Directory.GetFiles(@"c:\MyDir", "*.txt");

    Then to iterate through that list renaming each file individually (I assume your intention is) based on the first character. Doing whatever you need to do in the event of a duplicate being created.

    Re: Rename multiple files in one directory

    Hi

    it would work with Powershell in 2 Stages (perhaps just 1)
    is Powershell a option for you ?

    I don't think so I prefer a code rather than go with power shell option

    Re: Rename multiple files in one directory

    Hi,

    well you could use Substring

    Code:
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
            Dim s1 As String = "A.258551.txt"
            MessageBox.Show(s1.Substring(0, 1) & ".txt")
        End Sub
    that would result in A.txt

    but what happens after Z ?

    Re: Rename multiple files in one directory

    I don't think that this is useful file name changed every time and it not fixed I need a code which take the first character as condition in each case and ignore other characters

    If you only want the first character then https://docs.microsoft.com/en-us/dot...tframework-4.8 is probably what you need.

    The code was an example of how to use the SubString function, it wasn't code to solve your issue.
    This forum doesn't usually have people write the code that you want.
    The forum is for helping programmers fix issues with code they have written, or guide someone about possible ways to solve an issue.

    Sometimes, someone may have the desire to write the code out of interest or boredom, but I wouldn't count on it. You may be able to eventually get enough code examples from various people to put it together through persistently asking more pointed questions about particular parts of the problem, but you're taking your chances.

    well it was an example, you would/could use that 'SubString' Information in a ...For Each.. Loop to rename the Files

    in Post#10 you got a Link to read on the SubString method

    the demand 'Waiting your code' isn't appropriate
    try first , or wait for AxControls2 to respond
