    Looking to replace a web download system with RadFileExplorer and was wondering if there are any limits on the file size downloaded and what types of files can be downloaded?  I need to be able to download large video files (some over 1GB) and possibly other files (excel, word, text, etc.).  The demos seem to just use images.  My current solution loads the file into memory so it can control the file name and content type to force the download (so it doesn't open in the browser).  But my system doesn't work with loading large files into memory and is not very efficient.

    Please advise,

    Hi Jim Miles,

    File downloading is not a feature of the RadFileExplorer control and it does not control it. In your case you need to implement an ASHX handler that will serve the files to the browser and force it to open the file for direct download, not for preview. An example of such ASHX handler is used in this online demo (I have attached the source of the generic Handler to this thread) and I recommend you to use that approach in order to achieve the desired result. Please note that you need to change the MIME type of the file based on the type of the file. More details about the MIME types can be found on this site..

    I hope this helps.

    Best wishes,
