How to get the filepath and directory from a filename?

So I have this list of filenames.avi. each one comes from a different directory, path. I have a txt file of a list of those.

When they are all in the same folder thats easy, when I have each in one folder I must change the directory path accordingly for each file.

Thank you

You can use Directory.GetFiles() method and search sub-directories. I recommend to narrow down the search because you will get Exceptions when accessing restricted folders, but generally you could use a method like the following one which will return the path to the first occurrence of the filename or will return null:

public string SearchFileSystem(string filename)
{
    string [] files = null;
    try
    {
         files = Directory.GetFiles("C:\\", filename, SearchOption.AllDirectories);
    }
    catch (Exception e)
    {
         MessageBox.Show(e.Message);
    }
    return files==null?null:files.FirstOrDefault();
}

var sr = new StreamReader("filelist.txt");
while(!sr.EOF)
{
    string[] ListFiles = Directory.GetFiles("D:\movies\", 
                                            sr.ReadLine()/*your file name is the search pattern*/, 
                                            SearchOption.AllDirectories);
    if(ListFIles.Count > 0)
    {
        //File Found
        foreach(var f in ListFiles)
        {
            string fullPath = Path.GetFullPath(file);
            string fileName = Path.GetFileName(fullPath);
        }

    }

}

This will give you the file name

fullPath = Path.GetFullPath(file);
fileName = Path.GetFileName(fullPath);

and this will give you the file path

shortPath = fullPath.Substring(0, inputText.LastIndexOf("\"));

You will want to use the System.IO.Path class. The Path.GetDirectoryName will return the directory name (without a trailing '\' character).

There are other useful methods in the Path class, such as GetFileName and GetExtension.
