Downloaded file is truncated on a Windows Embedded CE 6.0 R3-based device


Consider the following scenario:
  • You have a Windows Embedded CE 6.0 R3-based image on a target device. This image contains the Windows Embedded CE 6.0 monthly update for December 2009.
  • You try to download a file to an external storage device of the target device by using Windows Internet Explorer. The external storage device has enough available capacity for the file. The size of the file is larger than the available capacity of the built-in storage of the device.
In this scenario, the downloaded file is truncated without any notification.


This issue occurs because the size of the cache folder on the device is not checked when the file is downloaded. Therefore, the file is truncated to the size of the cache folder.

Note Before the Windows Embedded CE 6.0 monthly update for December 2009 is installed, files are downloaded to the cache folder first, and then the files are copied to the destination folder. 


After you install the following update, the download process checks the size of the cache folder. If the size of the cache folder is not at least 100 kilobytes larger than the size of the file, the file is downloaded to the destination folder directly.
