Since some people asked me to improve FSEnum unit (see this post). I decided to give it another go and add some features and improve the others.

So what’s new?

• Optional Boolean parameter for all methods that tells the enumerator whether to return the relative paths (like it did before) or absolute ones.
• There are two levels of “mask matching” (if the enumeration is recursive). The first level allows everything to pass since you need to recurse into all directories. The real mask matching is done at the second level using the TMask (unit Masks).
• Two new methods (overloaded): FileSystemEntries which returns an enumerable over TFileSystemEntry structure.
• A new TFileSystemEntry structure that contains more information about a file/directory.

The next example shows the use of TDirectory.FileSystemEntries method:

var
  Entry: TFileSystemEntry;

begin
  { Show all read-only executable files on drive I: bigger than 1MB }
  for Entry in TDirectory.FileSystemEntries('i:', '*.exe', true) do
    if (Entry.Size > 1000000) and Entry.IsReadOnly then WriteLn(Entry.FullName);

  ReadLn;
end.

The unit is the same (has been updated!)  and can be found here: [download#40]
