How to increase default File Upload size in ASP.Net ?


By default, ASP.Net restricts the file uploaded to the server to be 4 MB. We can increase this setting in Web.Config through the <httpRuntime> tag.
 The below configuration setting is configured for all default values.

<httpRuntime
 executionTimeout="110"
 maxRequestLength="4096"
 requestLengthDiskThreshold="80"
 useFullyQualifiedRedirectUrl="false"
 minFreeThreads="8"
 minLocalRequestFreeThreads="4"
 appRequestQueueLimit="5000"
 enableKernelOutputCache="true"
 enableVersionHeader="true"
 requireRootedSaveAsPath="true"
 enable="true"
 shutdownTimeout="90"
 delayNotificationTimeout="5"
 waitChangeNotification="0"
 maxWaitChangeNotification="0"
 enableHeaderChecking="true"
 sendCacheControlHeader="true"
 apartmentThreading="false" />
 
To increase the default upload size, we need to increase the value of maxRequestLength property to whatever we want in KB. Default is 4096 KB(4MB).


To upload 100 MB, set
maxRequestLength="102400"


Copy the above configuration inside <System.Web> tag in Web.Config.
