Basic Examples  (2)

Check if a file exists:

Wolfram Language code: FileExistsQ[FileNameJoin[{$TemporaryDirectory, "temp.txt"}]]

Create a file:

Wolfram Language code: Put[FileNameJoin[{$TemporaryDirectory, "temp.txt"}]];

Check if the file exists:

Wolfram Language code: FileExistsQ[FileNameJoin[{$TemporaryDirectory, "temp.txt"}]]

Delete the file:

Wolfram Language code: DeleteFile[FileNameJoin[{$TemporaryDirectory, "temp.txt"}]]

Scope  (2)

Check if the file specified by the File object exists:

Wolfram Language code: file = CreateFile[];
Wolfram Language code: FileExistsQ[File[file]]

Create a reference to a new anonymous cloud object:

Wolfram Language code: obj = CloudObject[]

The cloud object does not yet exist in the Wolfram Cloud:

Wolfram Language code: FileExistsQ[obj]

Create the cloud object by putting an expression in it:

Wolfram Language code: CloudPut[10!, obj];

Now the cloud object exists in the Wolfram Cloud:

Wolfram Language code: FileExistsQ[obj]

Delete the object:

Wolfram Language code: DeleteFile[obj]

The cloud object no longer exists:

Wolfram Language code: FileExistsQ[obj]
