I am first getting the file bytes
<font color='blue'>byte</font> fileBytes = <font color='#2b91af'>File</font>.ReadAllBytes(destinationFilePath);
And then push the file out
return File(fileBytes, <font color='#2b91af'>FileContentType</font>.ApplicationOctetStream, fileName);
For small files this is great but for big files like 20mb and above, the conversion takes time.
How can i make it better so that conversion time gets better?
Is there some third party component available that can do the job better?
