Size Limit

  Asked By: Ruchir    Date: Aug 08    Category: Sharepoint    Views: 3228

We have been trying to put our 16.3MB zipped Board
Papers onto our WSS 2.0 site and the zip file is corrutpted when we try
to download and open it.

Is there some arbitary limit to document or
up/download sizes?

Yes, in fact there is a size  limit of 16mb that I believe can be changed. I
think it's a registry change but I haven't gotten that far yet.

Make sure you have the lastest WSS 2.0 Service Pack.

In the Administrators Guide, look for a section called "Large file  Support"
...it's actually in the SP1 release notes section of the Admin Guide (and a
little hard to locate).

That being said, you shouldn't have any problem with 16M ZIP file.

Here's the section from the WSS 2.0 Admin Guide:

Configuring Large file  Support

The biggest change included in Windows SharePoint Services SP1 is the
support for uploading large files. By default, the maximum size  for
uploading files is set to 50 MB. If you need to be able to upload larger
files (such as when you use smigrate.exe to migrate a site  between servers),
you can change this setting to any value up to 2 GB (2047 MB).

To configure large file support you must increase the default upload size in
SharePoint Central Administration. You may also need to perform the
following additional actions (depending on your hardware configuration):

* Tune the Microsoft Internet Information Services (IIS) connection
timeout setting.

The default timeout for connections in IIS is 120 seconds (2
minutes). Depending on your maximum file size and how long it takes for the
file to be uploaded, you may not need to change this setting. If, however,
IIS is timing out when you upload large files, you can change this property
to ensure that larger files can be uploaded successfully.

* 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. If you notice performance or
scale problems on the client or server, then you may need to tune this
setting to get the performance you are targeting. Note that if you raise the
chunk size too high, the files might use up too much front-end memory and
you may need to lower this setting.

* Increase the maximum size limit  for Web Parts.

By default, the maximum size limit for a Web Part is 1 MB. If you
need to accomodate large Web Parts, you can change this setting in the
web.config file for your server or servers running Windows SharePoint

Increase the maximum upload size

1. Click Start, point to All Programs, point to Administrative Tools,
and then click SharePoint Central Administration.

2. Under Virtual Server Configuration, click Configure virtual server

3. On the Virtual Server List page, click the virtual server you want
to change.

4. On the Virtual Server Settings page, under Virtual Server
Management, click Virtual server general settings.

5. Under Maximum upload size, type the maximum file size (in MB) that
you want to allow to be uploaded.

6. Click OK.

If IIS is timing out when you upload large files, you can configure the
Connection timeout setting in IIS to allow more than the default 120 seconds
(2 minutes).

Tune the IIS connection timeout

1. Click Start, point to All Programs, point to Administrative Tools,
and then click Internet Information Services (IIS) Manager.

2. Right-click the virtual server you want to configure, and then click

3. Click the Web Site tab.

4. In the Connections section, in the Connection timeout box, type the
number of seconds you want IIS to wait before timing out.

5. Click OK.

Increase the default chunk size for large files

The large-file-chunk-size property must be set from the command line. This
property is configured for a server or server farm, and cannot be configured
for an individual virtual server. To set this property, use the following

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

After making a change to this property, you must restart IIS. You can
restart IIS by typing iisreset on the command line.

I think there's a hard limit  of 10 MB for list and site  template upload sizes  in
WSS v2. In v3 you can adjust that size  to 50 MB.

Its a command line fix not via registry. You can move up to 500mb I believe. I
have the command on my blog post from 2 to 3 weeks back

Stsadm.exe -o setproperty -pn max-template-document-size -pv
