Unsure how to set MaxSize for .flv file in config.asp

Hi

I have just tried to upload a 2.9MB .flv file using ckfinder, I get the error

Invalid file. The file size is too big.

I am sure that IIS is setup to accept files up to 20MB

So is the problem in the code below, I dont know how to edit the code below to ensure it will allow say up to 8MB.

Also if a flash .flv file is uploaded to the fck editor using ckfinder, how does it display on the webpage???

Thanks, James

'maxSize is defined in bytes, but shorthand notation may be also used.
'Available options are: G, M, K (case insensitive).
'1M equals 1048576 bytes (one Megabyte), 1K equals 1024 bytes (one Kilobyte), 1G equals one Gigabyte.
'Example: 'maxSize' => "8M",

CKFinder_Config.Add "DefaultResourceTypes", ""
