Timeout on downloading folder

[graymouser]

Hi there,

Wondering if anyone here might have an insight on this, we have a client who has shared with us (via a SharePoint URL) a large OneDrive folder full of images that they would like us to download periodically. Using the 'Download' button/link in the top right to download the entire folder times out before it is completed. We are not sure of the completed file size as it keeps timing out, so far the largest size we've gotten before timeout is 19gb. We know that it is timing out as the zip file we get is always corrupted and will not extract. The file download doesn't appear to support resuming which would potentially solve this.

Since it's another company's data I'd rather not share the URL here even though I realise that would be helpful for debugging.

Any thoughts or help would be greatly appreciated!

There are tools or PowerShell scripts that provide similar functionality. See e.g. https://appsource.microsoft.com/en-us/marketplace/apps?search=sharepoint%20download%20zip&page=1 or http://www.slimapplications.com/product/explorer/

The best tool/scripts depends on your requirements:
- do you need to keep the SharePoint modification date
- do you need to export the SharePoint folder structure
- does the tool support parallel download threads
- can the tool handle long running requests and automatically refresh security tokens

Please note that the link to the Explorer tool will place the content into separate zip files (e.g. 500 MB each) because the tool is browser-based.

What download speeds do you experience? I just did a test with the explorer tool by downloading a folder structure with 1.3 GB files of various sizes from SharePoint Online and that took 540 s. (2.4 MB per sec).
