Question

How can I see all open upload sessions under a SharePoint/Team Site Folder?

Hein Moe Thu 10

I have flows and scripts that automatically move files/folders under a SharePoint/Team Site if they meet a certain criteria. This works well except for a case in which a folder is moved while a user is still uploading files to that folder. The upload would fail because the folder no longer exists.

I would like to know if there are any ways to detect upload sessions opened under a site or folder so that the script can wait for them to complete before moving the folder.

Using the Graph API, I noticed that a when a large file is being uploaded, a driveItem of size 0 is initially created and the size changes after the upload is completed. However, I don't see a way to differentiate between a file currently being uploaded and an empty file.

Would it be possible for you to have a specific upload folder. Once they are finished uploading they can then be moved to the folders meant to be sorted? Another work around would be an automation that creates a finished file when a file is fully uploaded, then moves the file based on criteria.

example: x.file uploading into upload folder

x.file finishes upload

x_done.file is created

system moves x.file to correct folder and deletes x_done.file

I already have a dedicated folder for users to upload in order to process the files. Using a Graph Subscription or a PowerAutomate Cloud Flow, I am able to detect changes made to that folder. However, they trigger when a user begins uploading a file (creation of a zero-byte file) and not when it is completed (file modified with content). I could try waiting until there are no zero-byte files, but this conflicts with actual zero-byte files that SharePoint Online allows to upload. Thus, I am trying to find another way to detect if a file is currently being uploaded.

Another work around would be an automation that creates a finished file when a file is fully uploaded, then moves the file based on criteria.

Unfortunately, that is not since I cannot control the upload behavior of the users.

As of my last knowledge update in January 2022, directly detecting ongoing upload sessions in SharePoint using the Microsoft Graph API can be challenging. The observed behavior of a file's size changing after upload completion might provide an indirect signal, but distinguishing between an ongoing upload and an empty file is not straightforward. Consider exploring alternative strategies such as monitoring file changes or implementing delays before moving folders to address potential issues with ongoing uploads. Always stay updated with the latest Microsoft Graph API documentation for any new features or improvements.
