Can you create a RegEx using folder structures in file names?

I have many folders structured thus:-

Author1
--first book title.txt
--second book title.rtf
--third book
----third book Title.doc
----Cover.jpg

Author2
--Another book title.epub

etc.

What I want:-

Author1
--first book title - Author1.txt
--second book title - Author1.rtf
--third book
----third book Title - Author1.doc
----Cover.jpg

Is there a RegEx that will append an " - " and the Author to each book title using the Multi Rename Tool? The first 2 books are difficult enough and I suspect the third book structure is impossible?

There can be 1 to many book titles and different file types involved in each Author folder.

I also suspect that RegExs only work at one level :(

I'll be more than happy with any solution that will save me manual effort :)

I have about 400 authors and I have already done a couple of hundred manually

Thanks in anticipation :D

Hi Louwind,

Welcome to the MSDN Forum.

Actually, I don't suggest you to use Regular expression.

Please try the following code:

    Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) Handles Button3.Click

        Dim dir As DirectoryInfo = New DirectoryInfo("D:\ChangeAuthors")
        For Each subDir In dir.GetDirectories()
            RenameFiles(subDir.FullName, subDir.Name)
        Next
    End Sub

    Private Sub RenameFiles(filePath As String, authorName As String)
        Dim dir As DirectoryInfo = New DirectoryInfo(filePath)

        For Each f In dir.GetFiles()
            My.Computer.FileSystem.RenameFile(f.FullName, f.Name & " - " & authorName & "." & f.Extension)
        Next

        For Each dic In dir.GetDirectories()
            RenameFiles(dic.FullName, authorName)
        Next
    End Sub

During my test, my folder structure is like this:

I hope this will be helpful.

Try

"^(?<head>\w+\sbook\s)(?=\w+\.(txt|rft|doc|equb))(?<title>.+)$"

Then use Replace method as follows(Use replace method):
```
Replace(input, @"${head}-${title}");
```
string

pattern = @"(?<head>\w+\sbook\s)(?=[^.]+\.(txt|rft|doc|equb))(?<title>.+)";
Regex r = new Regex(pattern);
string input = @"first book aa.txt";
Console.WriteLine(r.Replace(input, @"${head}- ${title}"));

Please Mark it as answer, if it helps solve your problem.
