Sharepoint uploading large files

Note The code in this article is provided as-is, without warranty of any kind, either express or implied, including any implied warranties of fitness for a particular purpose, merchantability, or non-infringement.

Note Consider the following best practices: Use a retry mechanism in case your upload is interrupted. When an uploaded file is interrupted, the file is called an unfinished file. You may restart uploading an unfinished file soon after the upload was interrupted. Unfinished files are removed from the server between 6 hours to 24 hours after the unfinished file was interrupted.

This removal period might change without notice. When an interruption occurs, the file remains locked for 15 minutes. If the next chunk of the file isn't uploaded to SharePoint Online within 15 minutes, the lock is removed.

After the lock is removed, you can resume uploading, or another user can start uploading the file. If another user starts uploading the file, your unfinished file is removed from SharePoint Online.

The period of time that the lock remains on a file after an upload is interrupted can change without notice. You might change the chunk size. We recommend using a chunk size of 10 MB. Increase the maximum upload size in the web. Increase the value of the Upload size. By default, Web Client file size limit is set to around 47 Mb. In the Value data box, click on Decimal, and type and then click OK. Increase the default chunk size for large files The large-file-chunk-size property sets the amount of data that can be read from a server running SQL Server at one time.

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.

I went and uploaded the file myself without no issues. After doing a speedtest, my upload is like 38 Mbps and hers is 3. Now I am left with the following theory.

Is there a time out when uploading files to Sharepoint Online? Perhaps Dropbox does not have one and uploads the file despite the crappy upload speed. I am thinking Here is the error message, has anyone seen this error when uploading files to Sharepoint Online? Or is it based on permissions? JJL I. T is an IT service provider.

Once data file is retrieved say of size MB , this solution will split the file MB automatically based on the pre-configured chunk size which should not exceed the size limit of MB 4. Each chunk then appended to the file uploaded in multiple iterations. Another prerequisite to demo is to have files of various sizes that we can use to upload to the document library. We made use of following command line utility to generate files of various sizes. This utility takes destination folder path and size of the file in KBs as input.

Here is the usage example of the command line utility:. Similarly we have generated other files too as shown below:. Step 1: Declare a variables to hold the document library name and folder path.

For production use we recommend to have these values in an external configuration file. Step 2: Reading files from the folder specified in path variable in Step 1.

Step 4: Generate unique upload id and get file name of the file to be uploaded.
