SharePoint 2010: Uploading Large Files to SharePoint

SharePoint 2010: Uploading Big Files to SharePoint

---

"The result with very large files being uploaded through any browser based API are:

1. Reliably transferring gigabyte or bigger files without breakages over a protocol like HTTP, which is amend suited for tiny transfers like images and text.
2. Not killing your browser considering it has to load all that in memory
3. Not killing your web server because, All that you lot upload through HTTP post, outset gets streamed into IIS Memory, w3wp.exe retentivity before the ENTIRE FILE finishes uploading before information technology is stored. Which means,
   
   • You cannot show an accurate and alive progress bar of the upload, IIS gives y'all no such accurate metric of an upload. All the counters it gives you are approximate.
   • Your w3wp.exe eats up all server memory – 4GB of it, for a 4GB upload.
   • A thread is kept busy for the entire duration of the upload, thereby greatly limiting your spider web server's capability to serve newer requests.
   • Kills effective load balancing.
     
4. Non killing your content database because,

As you are uploading a very large file, that large file gets written sequentially into the DB, and therefore a very big file severely impacts the database performance." [Sahil Malik on 24 Mar 2010]

Issues with uploading large documents to a document library

To begin with, the Back up for Large Files was one of the enhancements made in Windows SharePoint Services SP 1. By default, the maximum size for uploading files is set to l MB. The maximum file size that it tin go up to is 2,047 megabytes (ii GB).

Though SharePoint is meant to handle files that are upwardly to ii gigs in size, it is not practically viable and non recommended as well.

However, in that location are circumstances where files of much smaller size fail to upload which makes i wonder as to what could exist the reason, and hence this commodity. Beneath are the mutual error messages that you may come across while trying to upload large files based the operation organization and the version of IIS.

WSS three.0 or MOSS on a Windows 2003 server; when we upload any document larger that 50 Mb on whatsoever document library, we go an error message as:

"An unexpected error has occurred"

WSS three.0 or MOSS on Windows Server 2008 ; when nosotros upload whatsoever document larger that 28 Mb on any certificate library, nosotros get the error message as:

"The page cannot be displayed." In some circumstances, we may likewise go a "HTTP 404 - Page non establish" fault.

This tin can occur due to various reasons and this post lists a few of the possible causes and the workarounds for them.

WORKAROUND(s)

1. Increment the Maximum Upload Size for the Spider web Application from Key Administration site
   
   
   • Scan to Central Administration site and click on Application Direction
   • Click on 'Web Application Full general Settings' under 'SharePoint Web Application Management ' and choose the appropriate web awarding
   • Modify the value for 'Maximum Upload Size' property to specify the maximum size which is allowed for a single upload to any site nether the spider web application.
     Note: You tin cull multiple files and folders to be uploaded provided no single file or the collective size goes beyond 2 GB
   • A value of '1000' would set the max upload size to 1 GB. The maximum upload size cannot be increased beyond '2000' (2 Gb)
   • The default file size for upload is fifty Mb in IIS six.0) and 28 Mb for IIS 7.0.
2. Increase the connection fourth dimension-out setting in IIS
   
   Past default, the IIS connexion time-out setting is 120 seconds (two minutes). Follow these steps to increment the connectedness time-out setting:
   
   • In IIS director, expand the 'Sites' node and select the SharePoint site
   • Click 'Avant-garde Settings' from the deportment pane OR correct-click the SharePoint site, Manage Web site and click 'Advanced Settings'
   • Increase the 'Connectedness time-out' value (seconds); under 'Connection limits' from the 'Advanced Settings' dialog box to avoid IIS fourth dimension-outs when large files are being uploaded
   • You can specify the time-out value based on file size and the time taken for the file to be uploaded
   • You can also select the SharePoint site in IIS and click on the 'Limits' link in the actions pane.
     

3. Increase the maximum upload size in the web.config file of web awarding
   
   The maxAllowedContentLength property specifies the maximum length of content in a request in bytes and it needs to exist set on a Windows Server 2008 computer that has IIS vii.0-only installations.

   To change the value of the belongings via web.config, do the post-obit:

   Open up the spider web.config file of a web awarding located in %Inetpub%\Wwwroot\Wss\VirtualDirectories\<Virtual Directory> folder and add together the following code at the lesser, just earlier the close out of the <configuration> section of the Spider web.config file

               <Configuration>
   ..
   ..
   <arrangement.webServer>
               <Security>
                           <RequestFiltering>
                                      <requestLimits maxAllowedContentLength"52428800'/>
                           </requestFiltering>
                   </security>
   </organization.webServer>
   </configuration>

    This sets the value of the maxAllowedContentLength holding to 52428800 (in bytes) for the web awarding only.

    To change the value of the belongings via command-line, practise the following:

   • Open command prompt and go to 'C:\windows\system32\inetsrv' directory
   • Run the below command:

     Appcmd set config /section:requestfiltering /requestlimits.maxallowedcontentlength:unit of measurement

     Where the variable requestlimits.maxallowedcontentlength unit specifies the maximum length of content (in bytes). For example, to specify 2000000000 as the maximum length of content, type the following at the command prompt, then printing ENTER:

     Appcmd gear up config /section:requestfiltering /requestlimits.maxallowedcontentlength:2000000000

4. Increase the default chunk size for large files
   
   The large-file-chunk-size holding sets the amount of data that can be read from server running SQL Server at ane time. Points to remember:
   
   • If you have a file that is greater than your chunk size (such as 100 MB when the chunk size is set to five MB), the file would be read in 20 chunks (100 / 5).
   • The clamper size is not related to the maximum upload file size.
   • The chunk size simply specifies the amount of data that can be read from a file at one fourth dimension. By default, the large-file-chunk-size property is ready to five MB.
   • Be enlightened that if y'all prepare the chunk size too high, the files might employ a loftier amount of retention of the web front-end.
     
   In order to gear up the large–file–chunk–size property, we demand to apply the command line. This property is configured at a server or server farm level, and cannot exist configured for an private web application. To set this property, use the post-obit syntax:

   Stsadm.exe –o setproperty –pn large–file–chunk–size –pv <size in bytes>

5. Add the ExecutionTimeout Value in the web.config

   • "12\TEMPLATE\LAYOUTS" folder

     Open up the 'Spider web.config' file from the 'C:\Program Files\Mutual Files\Microsoft Shared\Web server extensions\12\TEMPLATE\LAYOUTS' directory. Add together the executionTimeout value that you want. For case, supercede the value as follows

     Existing lawmaking

     <location path="upload.aspx">
     <organization.web>
     <httpRuntime maxRequestLength="2097151" />
     </system.web>
     </location>

     Replacement Code

     <location path="upload.aspx">
     <system.web>
     <httpRuntime executionTimeout="999999" maxRequestLength="2097151" />
     </organization.spider web>
     </location>

   • Spider web App

     Open the web.config file located at 'C:\Inetpub\wwwroot\wss\VirtualDirectories\' folder and modify information technology as follows

     Existing line:             <httpRuntime maxRequestLength="51200" />
     Replacement line:     <httpRuntime executionTimeout="999999" maxRequestLength="51200" />

   • "12\CONFIG"

     Open the spider web.config located at "C:\Program Files\Mutual Files\Microsoft Shared\web server extensions\12\CONFIG" and change the 'maxRequestLength' property which by default should exist the following:

      <httpRuntime maxRequestLength="51200"/>

     Modify the value to friction match the other web.configs

6. Relieve the file and perform an ' IISreset /noforce'.

Big file support limitations

The following features exercise not support files larger than fifty MB

• Virus checking.
• Picture libraries.
• Streaming files.
• Client-side restoration of smigrate backup files (limited to 2 GB). The manifest files for an smigrate backup cannot be larger than two GB.
• Site templates (limit of 10 MB per site template, including content)

• You cannot upload files that are larger than 28 MB on a Windows Server 2008-based computer that is running Windows SharePoint Services 3.0 - KB944981
• Fault message when yous try to upload a large file to a document library on a Windows SharePoint Services 3.0 site: "Request timed out" - KB925083
