WSS by default allows 50MB files as its maximum upload. This works for some, but for others like myself, I needed it to be increased. I found plenty of blogs online to make this happen including this useful Microsoft document (http://support.microsoft.com/kb/925083), but it lacks one specific step that I needed - It and many of the other blogs only take into account WSS 2.0 and not 3.0. After searching the Internet and finding nothing, I chose to try and locate the menu myself.
After clicking through several menus I was able to identify the location of the Maximum Upload Size Field:
Go to
Start >
Administrative Tools >
SharePoint Central Administration >
"Application Management" Tab >
"Web Application General Settings" > Search for the Maximum Upload Size Field
Of course I should point out that there are more steps to get all of this functioning, but you can use the link above for the rest of that.
