Question

I’m trying to create a new file path in regex, in order to move some files. Say I have the path:

c:\Users\User\Documents\document.txt

And I want to convert it to:

c:\Users\User\document.txt

Is there an easy way to do this in regex?

If all you need is to remove the last folder name from the file path then I think it would be easier to use built-in FileInfo, DirectoryInfo and Path.Combine instead of regular expressions here:

var fileInfo = new FileInfo(@"c:\Users\User\Documents\document.txt");
if (fileInfo.Directory.Parent != null)
{
    // this will give you "c:\Users\User\document.txt"
    var newPath = Path.Combine(fileInfo.Directory.Parent.FullName, fileInfo.Name);
}
else
{
    // there is no parent folder
}
