Why uploaded file name not same original file name?

[Suwit]

I using RadAsyncUpload control and upload file by automatic after select file in "choose file to upload" dialog or drag and drop files to drop zone. I found file name at target folder not same original file name or cannot read.
Sample see attached image. Original file name is "SelfUpdatingLauncher.zip but in target folder is "1426758505493SelfUpdatingLauncher.zip".
Please advice.

Hi Suwit,

This is temporary name, created to avoid files overwriting. The uploaded file has such name only when it resides in the Temporary Folder. After the file submitted it will be renamed.

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" TemporaryFolder="~/Temp" TargetFolder="~/Uploas"></telerik:RadAsyncUpload>
<telerik:RadButton ID="btnSubmit" runat="server" Text="Submit"></telerik:RadButton>

Thank you for your response. I'm try follow you advice but not found uploaded file in target folder. 
Is possible save file to target folder instead temporary folder without code runat server?  
if yes, Have you any approach? 
if no, Is this limitation?

Make sure that you give write permissions to both folders. Do meantt without the runat="server" tag?
