Issues Uploading Large Files To SharePoint
Generally,
In SharePoint we encounter the below issues while uploading the larger files to
SharePoint web site. The issues it could be many reasons. we come to know the
Exact issue by checking the Application,ULS or any trace. Here in the below article,
I am mentioning the general cause of the issues and the resolutions that Occur
In my experience.Follow any below methods as per your issue.
·
"An
unexpected error has occurred"
·
"The
page cannot be displayed”
·
"An
unknown error occurred"
·
"HTTP
404 – Page Not Found”
·
“Request
timed Out’
1.Increase
the maximum upload size for the web application
Go to 'Start > All Programs >
Administrative Tools > SharePoint Central Administration > Application
Management'.
1.
Under SharePoint
Web Application Management, click 'Web application general settings’.
2.
On the Web
Application General Settings page, choose the appropriate web application.
3.
Under Maximum
upload size, type the file size which you want to upload and click on OK. You
can specify a maximum file size up to 2,047 megabytes.
Note:
Any upload size which is below 250 MB is
enforced directly through web app settings. Above 250 MB, you need to make a
some small change to the web.config
file to allow larger uploads. Repeat the steps listed below for all zones for
your web app all the servers which host the web application role.
- Open the web.config from
- 'C:\Inetpub\wwwroot\wss\VirtualDirectories\<Virtual
Directory>' folder and modify it as follows
<httpRuntime
maxRequestLength="51200" /> with <httpRuntime
executionTimeout="999999"
maxRequestLength="51200" />
- Perform an IISReset and
you should be good to go.
2. Increase the connection time-out setting in IIS
while
uploading large files, there are chances that the request will timeout. By
default, the IIS connection time-out setting is 120 seconds. Follow these steps
to increase the connection time-out setting,
·
Click Start,
point to All Programs, point to Administrative Tools, and then click Internet
Information Services (IIS) Manager.
·
Right-click the
virtual server that you want to configure, and then click Properties.
·
Click the Web
Site tab. Under Connections, type the number of seconds that you want in the
Connection time-out box,
and then click OK.
3. Increase the maximum upload size in the web.config file of web
application
In the
web.config file of web application which has issues to upload larger files or
getting the error the page can’t be displayed. Increase the value of the Upload
size.
4.Explorer view or Web client
issues
While
trying to use the explorer view, you may see the following error
“Error
0x800700DF: The file size exceeds the limit allowed and cannot be saved”
message
If
this is the case then the issue is most likely caused by a local restriction
set on Web Client service. By default, Web Client file size limit is set to
around 47 Mb. To increase this limit:
- Click Start, click Run,
type regedit, and then click OK.
- In Registry Editor,
locate the following registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClientParameters
- Right click on the FileSizeLimitInBytes and
then click Modify.
- In the Value data box,
click on Decimal, and type 4294967295 and then click OK.
- Quit Registry Editor
- Restart Web Client service
from Services.msc
5.Increase the default chunk size for large files
The
large-file-chunk-size property sets the amount of data that can be read from
server running SQL Server at one time.
- If you have a file that
is greater than your chunk size (such as 70 MB when the chunk size is set
to 5 MB), the file would be read in 14 chunks (70 / 5).
- The chunk 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 time. By
default, the large-file-chunk-size property is set to 5 MB.
- Check if the
'large-file-chunk-size' property is set or not
Stsadm -o
getproperty -propertyname large-file-chunk-size
- In order to set the
large–file–chunk–size property, we need to use the command line. This
property is configured for a server or server farm, and cannot be
configured for an individual web app server. To set this property, use the
following syntax:
Stsadm.exe –o setproperty
–pn large–file–chunk–size –pv <size in bytes>
- After making a change to
this property, perform an IISreset /noforce.
6.Add the execution Timeout value
Increase
the execution timeout for the upload page (upload.aspx) to prevent timeouts on
the page..
- Navigate to 'C:\Program
Files\Common Files\Microsoft Shared\Web Server
Extensions\12\TEMPLATE\LAYOUTS' folder on the SharePoint server.
- Open the 'web.config'
file in notepad or any other text editor and add the execution
Timeout parameter. For example, replace the value as follows
Existing code
<location path="upload.aspx">
<system.web>
<httpRuntime maxRequestLength="2097151" />
</system.web>
</location>
Replacement
code
<location path="upload.aspx">
<system.web>
<httpRuntime executionTimeout="999999" maxRequestLength="2097151" />
</system.web>
</location>
- Open the 'web.config'
file from the 'C:\Inetpub\wwwroot\wss\Virtual Directories\<Virtual
Directory>'folder and modify it as follows
Existing line :
<httpRuntime maxRequestLength="51200" />
Replacement line
: <httpRuntime executionTimeout="999999"
maxRequestLength="51200" />
