How to change the Maximum File Upload Size in SharePoint 2007.

 How to change the Maximum File Upload Size
 When a custom master page is applied, editing a list in Datasheet View
causes IE to just hang. I found this script hich solved my problem:
<script type="text/javascript">

function GCComputeSizing(GCObject)
{
if (TestGCObject(GCObject))
{
var fBIDI=(document.documentElement.currentStyle.direction=="rtl");
var lGCWindowWidth=document.documentElement.scrollWidth;
var
lGCWindowHeight=(document.documentElement.scrollHeight>document.documentElement.clientHeight)
? document.documentElement.clientHeight :
document.documentElement.scrollHeight;

var lGCObjectOffsetLeft=0;
var lGCObjectOffsetTop=0;
if (fBIDI)
{
lGCObjectOffsetLeft=-180;
lGCObjectOffsetTop=120;

}

else
{
lGCObjectOffsetLeft=32;
lGCObjectOffsetTop=-2;

}

var lGCObjectWalker=GCObject.parentElement;
while (lGCObjectWalker !=document.body)
{
lGCObjectOffsetLeft+=lGCObjectWalker.offsetLeft;
lGCObjectOffsetTop+=lGCObjectWalker.offsetTop;
lGCObjectWalker=lGCObjectWalker.offsetParent;
if (fBIDI)
if (lGCObjectWalker.offsetLeft > 0)
break;

}

lGCObjectOffsetLeft+=GCObject.parentElement.offsetLeft;
lGCObjectOffsetTop+=GCObject.parentElement.offsetTop;
glGCObjectHeight=lGCWindowHeight - lGCObjectOffsetTop;
if (glGCObjectHeight > lGCWindowHeight)
glGCObjectHeight=lGCWindowHeight
if (glGCObjectHeight < cGCMinimumHeight)f
glGCObjectHeight=cGCMinimumHeight;
if (fBIDI)
{
glGCObjectWidth=lGCWindowWidth+lGCObjectOffsetLeft;

}

else
glGCObjectWidth=lGCWindowWidth - lGCObjectOffsetLeft;
if (glGCObjectWidth > lGCWindowWidth)
glGCObjectWidth=lGCWindowWidth;
if (glGCObjectWidth < cGCMinimumWidth)
glGCObjectWidth=cGCMinimumWidth;

}
}

</script>
place it after core.js in your master page.


By default SharePoint allows a maximum file size of 50MB that can be
uploaded into any document library. This might be too much as you might not
want users downloading 50MB files over your LAN/WAN. To change the maximum
file size
1. Goto SharePoint Central Administration > Configure Virtual Server
Settings from Virtual Server List Page.
2. Select your server
3. Goto Virtual Server General Settings (in Virtual Server Management)
4. Change the value of the Maximum Upload Size in MB's.
If you increase the file size limit, your site might occassionally time out
for users while they are uploading files. To accomodate this increase the
default time out property for IIS.
