Few days back, on of my friend contact me for a solution.
He has implemented MOSS 2007 with SQL Express.
He use his SharePoint site as a repository for uploading/ maintaining all the files, even very large files like of 1 GB.
While uploading more than 20 MB he started getting error, so wee increase the file quota from the Central Administration and make it to 2 GB. But the error remain same which was “Request timed out”.
Then we increased the request time out from IIS. But still error was there. We were able to upload 300 MB files though, but not able to upload 1 GB file.
Then finally we got help from the KB article. Error message when you try to upload a large file to a document library on a Windows SharePoint Services 3.0 site: “Request timed out”
There we modify the web config under the layout folder location i.e. C:\Program Files\Common Files\Microsoft Shared\Web server extensions\12\TEMPLATE\LAYOUTS
Here we search the upload.aspx, and modify it to
We just add executionTimeout=”999999″ and then it allow us to upload the 1 GB file even.
The problem was with the upload.aspx page execution, which processing timeout expires, so with this it easily allow us to upload files with greater size.
