var lines = File.ReadAllLines(userVideosDirectory + "\\UploadedVideoFiles.txt");
File.WriteAllLines(userVideosDirectory + "\\UploadedVideoFiles.txt", lines.Skip(1));

Old school (without LINQ) is to start iterating at index 1.

for (int i = 1; i < files.Length; ++i)
{
   // do something with files[i], which is a line in the file.
}

Use Enumerable.Skip Linq extension method:

string[] files = File.ReadAllLines(userVideosDirectory + "\\UploadedVideoFiles.txt").Skip(1).ToArray();
File.WriteAllLines(userVideosDirectory + "\\UploadedVideoFiles.txt", files);

Using LINQ is the best approach in this case:

foreach (string file in files.Skip(1))
