Enum FEFlags

[Flags]
public enum FEFlags

Name	Description
AllDescendants	Enumerate all descendants, not only direct children. Also known as "recurse subdirectories".
IgnoreInaccessible	If fails to get the contents of the directory or a subdirectory because of its security settings, assume that the [sub]directory is empty. Without this flag then throws exception or calls errorHandler.
NeedRelativePaths	Let FEFile.Name be path relative to the specified directory path. Like `@"\name.txt"` or `@"\subdirectory\name.txt"` instead of `"name.txt"`.
OnlyFiles	Get only files and not subdirectories. Note: the dirFilter callback function is called just to ask whether to include children.
RecurseNtfsLinks	Also enumerate target directories of NTFS links, such as symbolic links and mount points. Use with AllDescendants.
SkipHidden	Skip files and subdirectories that have Hidden attribute.
SkipHiddenSystem	Skip files and subdirectories that have Hidden and System attributes (both). These files/directories usually are created and used only by the operating system. Drives usually have several such directories. Another example - thumbnail cache files. Without this flag the function skips only these hidden-system root directories when enumerating a drive: `$Recycle.Bin`, `System Volume Information`, `Recovery`. If you want to include them too, use network path of the drive, for example `@"\\localhost\D$\"` for `D` drive.
UseRawPath	Don't call pathname.normalize and don't throw exception for non-full path.
