Namespace:  Aspose.Words.Saving
Assembly:  Aspose.Words (in Aspose.Words.dll) Version: 20.3
Syntax
public string TempFolder { get; set; }

Property Value

Type: String
Remarks

When Aspose.Words saves a document, it needs to create temporary internal structures. By default, these internal structures are created in memory and the memory usage spikes for a short period while the document is being saved. When saving is complete, the memory is freed and reclaimed by the garbage collector.

If you are saving a very large document (thousands of pages) and/or processing many documents at the same time, then the memory spike during saving can be significant enough to cause the system to throw OutOfMemoryException. Specifying a temporary folder using TempFolder will cause Aspose.Words to keep the internal structures in temporary files instead of memory. It reduces the memory usage during saving, but will decrease the save performance.

The folder must exist and be writable, otherwise an exception will be thrown.

Aspose.Words automatically deletes all temporary files when saving is complete.

Examples
Shows how to save a document using temporary files.
Document doc = new Document(MyDir + "Rendering.docx");

// We can use a SaveOptions object to set the saving method of a document from a MemoryStream to temporary files
// While saving, the files will briefly pop up in the folder we set as the TempFolder attribute below
// Doing this will free up space in the memory that the stream would usually occupy
DocSaveOptions options = new DocSaveOptions();
options.TempFolder = ArtifactsDir + "TempFiles";

// Ensure that the directory exists and save
Directory.CreateDirectory(options.TempFolder);

doc.Save(ArtifactsDir + "DocSaveOptions.TempFolder.doc", options);
