AjaxFileUpload don't flush %windir%\temp\

I have a considerable issue, found by hosting several ASP.NET websites (7 ~ 15) with the AjaxFileUpload server control of the AjaxControlToolkit library (the latest version):

while the control is processing file, temporary files are saved in the system temporary folder (%windir%\temp), but it won't flush that after the request is complete.

I don't know if this is a folder permission problem, or an AjaxFileUpload bug.

This is the result after 2 years of hosting, a huge stack of temporary folders:

There is any way to override that behavior, or i must manually flush that folder every 1-2 months ?

Thanks in advance

Solution

  • If you don't use SaveAS() method, you must deleted yourself.

    example:

    protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e) {
    // Save uploaded file to a database table

    e.DeleteTemporaryData();
}
