  What is the difference between EnumerateFiles and EnumerateFileSystemEntries in .NET 4?

Currently i use this to get all files in a folder:

IEnumerable<string> files;
files = Directory.EnumerateFiles(datapath, "*", SearchOption.AllDirectories);

where datapath is just a string with the folder path.

With this i get all files and also the folders that contain files, but if i have empty folders i don't get them.

I thought about using Directory.EnumerateDirectories but than i would have all directories, even those that where already found by Directory.EnumerateFiles

Is there a better way to handle this?

  @Joel GetFileSystemInfos() will return only after all results are found. It's better to use the Enumerate... methods. In any case that snippet doesn't do what the OP asked, it only checks whether the root folder is empty or not, in a rather expensive way. EnumerateFileSystemInfos().Any() would do the same but return immediatelly

You should use Directory.GetDirectories and then for each folder and file you can ran foreach loop. You can read more about this solution here http://www.csharp411.com/c-copy-folder-recursively/

You should use Directory.GetDirectories and then for each folder and file you can ran foreach loop. You can read more about this solution here http://www.csharp411.com/c-copy-folder-recursively/
