Uploading a large file using FileUpload Control in ASP.NET

By default FileUpload control in asp.net uploads upto 4MB size of files and it doesn't allow 'exe' files.

To increase the file size limit that a fileupload control can upload, just add the following line to web.config

< system.web >
           < httpruntime executiontimeout="500" maxrequestlength="4096" >
< /system.web >

Here 'executionTimeout' in milliseconds and 'maxRequestLength' in kb. So, increase the maxRequestLength to upload large files.
