NotebookAutoSave

is a notebook option that specifies whether the notebook should automatically be saved after each piece of output generated by evaluation in it.

Examples

Basic Examples (1)

Create a notebook with NotebookAutoSave->True and save it to a file:

Wolfram Language code: nb = CreateDocument[Map[ExpressionCell[Defer[# + #], "Input"]&, Range[3]], NotebookAutoSave -> True];

Wolfram Language code: fname = FileNameJoin[{$TemporaryDirectory, "autosave.nb"}];

Wolfram Language code: NotebookSave[nb, fname]

Check the time of creation of the notebook file:

Wolfram Language code: DateString[Date /. FileInformation[fname], "Time"]

When you evaluate an input, the notebook is automatically resaved:

Wolfram Language code:

SelectionMove[nb, Next, Cell];
SelectionEvaluate[nb]

This shows the newer modification time of the file:

Wolfram Language code: DateString[Date /. FileInformation[fname], "Time"]

Close the notebook and delete the temporary file:

Wolfram Language code:

NotebookClose[nb];
DeleteFile[fname];
