When a file is created(properties only) Trigger in OneDrive For Business Connector.(Power Automate Cloud flows)

Japanese version.

This trigger is fired when a new file is created in a specified folder on OneDrive.

This trigger acquires metadata (additional information) of the newly created file.

Unlike "When a file is created", it does not retrieve file content, but it uses less file content in the trigger and can be supplemented with "Get file content" if necessary. The information available as dynamic content is also better here. Therefore, this action will be used more frequently.

How to use

Click on "Create" then "Automated cloud flow".

Specify any name for "Flow name" and select "When a file is created(properties only)".

When both are specified, "Create" will change color and click on it.

Set parameters.



Specify the folder to be detected.

When selected, it looks like a folder path, but it is only a display and the substance is an ID.

If you delete the specified folder and then create a folder with the same name, it will be treated as a different folder.
In such a case, an error will occur that the folder does not exist, so it must be re-specified in the flow.

Include subfolders

  • No…Only the specified folders will be detected.
  • Yes…Folders below the specified folder will also be detected.

If not necessary, "No" is recommended.

Number of files to return

Specify the number of files to be handled in one trigger, from 1 to 100.

This parameter is used to control the number of simultaneous processes when a large number of files may be generated at one time.

By default, it is one file per trigger, no matter what the number is.

It must be "Settings" to take effect.

Set "Split On" to "Off" and "Limit" to "On" and change the "Degree of Parallelism".

If "Split On" is "Off", dynamic content becomes an array and must be iterated through "Apply to each".

For example, set the "Number of files to return" to 25 and the "Degree of Parallelism" to 2.

Then, if 100 files are created, the following operation is performed.

  • Two triggers to process 25 files are launched at the same time.
  • After a short time, two triggers to process 25 files are triggered at the same time.

Thus, it is possible to adjust the load for mass file operations.
