    In fileexplorer there is the abilty to upload files. Right now if I upload a file that has the same name as an existing file I get a prompt that tells me the file already exist. What I want to do is give the newfile a unique name and save it. For example I upload file named "Fred.txt" if "Fred.txt" already exist I will try "Fred-01.txt, Fred-02.txt, Fred-03.txt..." until I find one that doesnt exist then save the file with that name. How?


    <telerik:RadFileExplorer ID="RadFileExplorer1" runat="server" OnClientItemSelected="OnImageSelected" EnableCopy="true" EnableAsyncUpload="true" >

    <Configuration MaxUploadFileSize="20480000" />

    Hi Fred,

    To achieve this you need to override the StoreFile() method of RadFileExplorer's content provider. Please take a look at the following help article for more detailed information on how the content provider works:
    Using custom FileBrowserContentProvider

    Also, a similar example is available in the following KB article:
    Giving the uploaded files unique names

    Best wishes,
    the Telerik team
