RadUploadTemp folder not getting cleaned up

[Albert Shenker]

I find that the RadUploadTemp folder is not being cleaned up. I have the various files RadAsyncUpload creates in that folder from months ago. Is this expected behavior? If so, is there a way to get the files to be cleaned up in some automatic fashion, or do I need to write some custom code to go in and delete files older than a certain time?

Hi Albert,

The expiration time for the files in the temporary folder could be controlled via the TemporaryFileExpiration property of the RadAsyncUpload. Please adjust this property to the desired time interval.

Hi Dimitar,

I did set the RadAsyncUpload property as shown below.

RadAsyncUpload1.TemporaryFileExpiration = new TimeSpan(0, 0,20, 0, 0);

It is suppose to delete the file after 20 mints but still I can see the files there. I am using Telerik.Web.UI.dll(Ver 2010.3.1317.20), IE 7.0 browser, .Net 2.0.

Thanks,
Raji

Hello Raji,

Since you are using rather old version of the controls, could you please check whether the same problem occurs with a newer version? Please note that in the latest version of the controls we are not providing .Net 2.0 dll, so you should build your own. A document with instructions on how to build .Net 2.0 dll is provided with the source code of the controls.

Hi Dimitar,

In order to test I need to upgrade the .net framework. Can you verify if this works? Is it possible to use the latetest version of the Telerik controls with .Net 2.0. If yes can you send me the link to the documentation.

Thanks,
Raji

I have the same behavior on .Net 3.5 with version 2011.3.1305.35. Most of the files get cleaned up but some of them are still there after months.

Hi John,

Could you specify whether there is something in common between the files that haven't been cleared, so we could perform some testing locally?

Kind regards,

Cant really see anything. Attached a file with small sample of the catalog. I'm running on IIS6.

Hi John,

Your error log provides the exact reason why some of your files are not deleted:
Exception information: 
    Exception type: IOException 
    Exception message: The process cannot access the file 'C:\Apps\405000\WebSites\PublicWeb\App_Data\RadUploadTemp\1328611694996CVMYDOC-En.pdf' because it is being used by another process.

As it appears at the time when your temporary files should be removed, there is some process which is using them.

Yes you are right. Im using session to store the uploaded files as DimeAttachment. I guess that if the the session doesn't release the file stream before the files are up for deletion this error would occur.

Hello John,

You are right as well, indeed the files could not be deleted while some process is using them.

All the best,
