Problem: Im having problems with large files in SharePoint
Problem: Im getting request timeouts dealing with large file operations
1.Make sure the Maximum Upload Size setting on the Web application general settings page for the web application in question is set to a value larger than the file(s) being uploaded.
2.Use the multi-file upload option vs. the single-file upload option even if uploading a single file.
3.It could be a request timeout. See Microsoft knowledgebase article number for information on addressing this issue.
a.Optionally, add the following node to the LAYOUTS\web.config to catch other operations (check-in, version restore, etc.):
<httpRuntime executionTimeout=999999 />
4.If SharePoint (WSS or MOSS) web front-end server(s) is running on 32bit versions Windows 2003 or 2008, consider moving to a 64bit version.
Please see the Large File Support document, found by clicking the Help link on the Large File Upload page.
If not already enabled, make sure the ID that is upgrading the farm has full control for the Web Application hosting the My Site Host. (Select the Web App, User Policy>Add user.) If enabling this access is not preferred, temporarily add the ID, then disable externalization on the StoragePoint profile, save it, enable externalization on the profile, save it, and remove the user from the Web App user policy when complete. Otherwise, my site users may see an error when they try to use the large file upload window on their my site.
Farm administrators can view information about the health and storage utilization of their Metalogix StoragePoint implementation.
