Question

I have over 1000 files in a folder with names like abc_1, abc_2 … abc_n

I want to delete this prefix ‘abc_’ from all the files. Any chance to not doing this manually because there are over 1000, and it will be a pain.

How can do this with c# ?

Answer 1

You can try with this code

DirectoryInfo d = new DirectoryInfo(@"C:\DirectoryToAccess");
FileInfo[] infos = d.GetFiles();
foreach(FileInfo f in infos)
{
    File.Move(f.FullName, f.FullName.Replace("abc_","")); // Careful!! This will replaces the text "abc_" anywhere in the path, including directory names.
}
