Aurigma Upload Suite 8.0.67
BaseUploadControl..::.TempDirectory Property HTML5/Flash Uploader ASP.NET
Gets or sets a path to the folder where the upload session cache should be saved.
Assembly: Aurigma.ImageUploaderFlash (in Aurigma.ImageUploaderFlash.dll)
By the moment when the FileUploaded or AllFilesUploaded event is fired, the BaseUploadControl has already completed parsing of HTTP POST request(s) and saved files to a temporary folder specified by this property. Then, when you call the ConvertedFile.SaveAs(String) or ConvertedFile.MoveTo(String) method, files from this temporary folder are copied or moved to the specified path. Thus, it is recommended to select temporary folder on the same disk where your file storage is located.
This recommendation is also appropriate for autosave functionality.
