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.
