Answer 1

This worked for me:

var files = new DirectoryInfo(@"C:\Users\Alex\Desktop").GetFiles()
    .Where(arg => !arg.Attributes.HasFlag(FileAttributes.Hidden) || arg.Extension != ".docx")
    .ToList();

You can also add limiting by file name prefix:

var files = new DirectoryInfo(@"C:\Users\Alex\Desktop").GetFiles()
    .Where(arg => !(arg.Attributes.HasFlag(FileAttributes.Hidden) && arg.Extension == ".docx" && arg.Name.StartsWith("~$")))
    .ToList();
