Basic Examples  (2)

$UserBaseDirectory is a directory:

Wolfram Language code: FileType[$UserBaseDirectory]

A typical file in the Wolfram System program layout:

Wolfram Language code: FileType[FileNameJoin[{$InstallationDirectory, "Documentation", $Language, "PacletDB.m"}]]

Scope  (4)

Find the type of the file specified by the File object:

Wolfram Language code: filename = CreateDirectory[];
Wolfram Language code: FileType[File[filename]]

Create a new cloud object:

Wolfram Language code: obj = CloudPut[10!]

Check that the file type is File:

Wolfram Language code: FileType[obj]

Create a new directory in the Wolfram Cloud:

Wolfram Language code: dir = CreateDirectory[ CloudObject[]]

Check that the file type is Directory:

Wolfram Language code: FileType[dir]

CloudObject only creates a reference to a new anonymous cloud object, so its file type is None:

Wolfram Language code: FileType[CloudObject[]]
