Maximum Filesize attachment?

Can anyone tell me the maximum size of a file allowed when uploaded from an aspx page please & are there any settings to alter this?

Thanks!

The default filesize is 4MB and of course there is a way to change it.

Change the machine.config file to update the filesize:

maxRequestLength is the file size

<httpRuntime executionTimeout="90" maxRequestLength="4096"
useFullyQualifiedRedirectUrl="false" minFreeThreads="8"
minLocalRequestFreeThreads="4" ppRequestQueueLimit="100"/>
