Configuring the IIS Maximum File Upload Size
Configuring the IIS 'Max file upload size' with AppCmd or PowerShell.
1 min read
By default, IIS 7 only allows uploading files <30MB. You can change this setting GLOBALLY via appcmd.exe or PowerShell. “maxAllowedContentLength” is specified in bytes, so the example allows 100MB.
AppCmd
%systemroot%\system32\inetsrv\appcmd.exe set config -section:requestFiltering -requestLimits.maxAllowedContentLength:104857600PowerShell
Set-WebConfigurationProperty `
-filter /system.webserver/security/requestfiltering/requestLimits `
-name maxAllowedContentLength `
-value 104857600
