Gets the root folder in the temporary app data store.

Syntax


var temporaryFolder = applicationData.temporaryFolder;

Property value

Type: StorageFolder

The file system folder that contains the files.

Remarks

You can access files in the temporary app data store using the "ms-appdata:///temp/" protocol. For example:

<img src="ms-appdata:///temp/myFile.png" alt="" />

Windows Phone 8

This API is not implemented and will throw an exception if called.

Examples

Use the file APIs, such as Windows.Storage.StorageFolder.CreateFileAsync | createFileAsync and Windows.Storage.FileIO.WriteTextAsync | writeTextAsync, to create and update a file in the temporary app data store. This example creates a file named dataFile.txt in the temporaryFolder container and writes the current date and time to the file. The ReplaceExisting | replaceExisting value from the CreationCollisionOption enumeration indicates that the file should be replaced if it already exists.

Next, this example opens the dataFile.txt file created and reads the date from the file using Windows.Storage.FileIO.ReadTextAsync | readTextAsync.

JavaScript

C++


var applicationData = Windows.Storage.ApplicationData.current;
var temporaryFolder = applicationData.temporaryFolder;

// Write data to a file

function writeTimestamp() {
   temporaryFolder.createFileAsync("dataFile.txt", Windows.Storage.CreationCollisionOption.replaceExisting)
      .then(function (sampleFile) {
         var formatter = new Windows.Globalization.DateTimeFormatting.DateTimeFormatter("longtime");
         var timestamp = formatter.format(new Date());

         return Windows.Storage.FileIO.writeTextAsync(sampleFile, timestamp);
      }).done(function () {      
      });
}

// Read data from a file

function readTimestamp() {
   temporaryFolder.getFileAsync("dataFile.txt")
      .then(function (sampleFile) {
         return Windows.Storage.FileIO.readTextAsync(sampleFile);
      }).done(function (timestamp) {
         // Data is contained in timestamp
      }, function () {
         // Timestamp not found
      });
}
