Is it Possible Get Unspecified File Name From OneDrive with Power Automate

[ByzKzlky]

Hello,

I reaaly need an urgent help.
I'm new on Microsoft Power Automate and I'm trying to built a flow.
This flow can be summarised like below:

1. Receive Email
2. Save Attachments to OneDrive
3. Copy OneDrive file to another OneDrive Folder (there are problem at this point. The file name can be changed for every email attachment and I need to get current file name to process other stpes. I've tried to use expressions to get generic name. First I've initialized a variable but I couldn't use it anywhere. Then I try to get the file name such as :concat('/xxxx_folder/',variables('name of initialized variable') but it didn't work.
4. After getting the file I need to get excel files and copy to another template excel file.
5. And final step is sending this new file as attachment with an email.

Is there any way to get unspecified file name and use it in other steps?
Thanks.

Hey @ByzKzlky ,

If what's blocking you in step #3 is to figure out the file name in step #2 (the saved attachment), wondering if you can try using the "Id" variable out of the Create file action in #2:

Normally you can use to reference dynamically created files during a flow execution.

Hope this helps!
