I am working with a website created with PHP, MySQL, & IIS 7. Part of the purpose of the site is to be an access point for customers to upload and download content. Some of the files are large. Is there a limit on how much data can be uploaded or downloaded to a site? I was able to upload a small 12mb file. When I attempted a 50mb the page fails. I need to get this where it will upload these large files(maybe as much as 100mb).

Yes, check the PHP.ini file for upload_max_filesize and  post_max_size

They are both set at 100M.

Please verify it with phpinfo();

However remember that upload large files trough http is slow and in case of network problems you have no resume!

...and note that using a browser to handle very large files can freeze it

IIS has it's own limits in addition to what PHP sets.  Here's some info: http://www.cyprich.com/2008/06/19/fixing-file-upload-size-limit-in-iis-7/

Also you can check the "max_execution_time" value to ensure the scripts
runs over a huge amount of time.... (example)

ini_set("max_execution_time","3600");  // one hour max execution

Sorry for the delay. I read the article DaveBaldwin suggested and I edited the web.config file but I got less than satisfactory results. How do edit this file? What program should I use. I read about the file but I'm not sure I 'got' what was being presented.

the web.config file is an XML file with configurations for some web directory or application
(it's parto of all ASP.NET applications when they are created as "application" in IIS)

If you want to apply this configuration for all applications you need to edit the web.config
file in the rrot IIS directory (C:\inetpub\wwwroot\). If you prefer to create a custom web.config file in the web application directory you need to change the folder in IIS administration using  "convert to application" option. Then you can edit or create  a web.configfile  in the root of your web app.

I'm not sure that this configuration affects PHP based web applications, but you can try if it works.
