Kai2,

 

It looks like you are using verson 6.0. Please note that the latest version is version 6.1.2.

In Cute Editor, we use Ajax Uploader to handle file uploading.  Ajax Uploader is an easy to use, hi-performance ASP.NET upload component which allows you to upload files to web server without refreshing the page.

 

By streaming uploads directly to an output stream, rather than loading them into memory, Ajax Uploader achieves a level of scalability and performance impossible to reach with ASP.NET's built-in functionality.

 

To achieve this, Ajax Uploader needs a temp folder to hold temp files.

 

Once files are uploaded, Ajax Uploader will clean the temp files in the temp folder.

 

Hope it helps.

 

Let me know if you have any further questions.
