({{, (RefLink[IncludeDirectories, paclet:ref/IncludeDirectories]) 
is an option that specifies whether directories are included in evaluations.}})

OpenersNotesSection(Spacer1)Details

With the default setting IncludeDirectories->(RefLink[False, paclet:ref/False]), directories are excluded from evaluations.

With the setting IncludeDirectories->(RefLink[True, paclet:ref/True]), functions like (RefLink[FileSystemMap, paclet:ref/FileSystemMap]) will apply to both directories and files.

By default, (RefLink[FileSystemMap, paclet:ref/FileSystemMap]) excludes directories:

FileSystemMap[FileDate,$InstallationDirectory,IncludeDirectories->False]

When (RefLink[IncludeDirectories, paclet:ref/IncludeDirectories]) is set to (RefLink[True, paclet:ref/True]), a key of (RefLink[All, paclet:ref/All]) will be added for the evaluated directory:

FileSystemMap[FileDate,$InstallationDirectory,IncludeDirectories->True]
