Hey,

I have a PowerApps through which users are able to upload multiple files to a Sharepoint Library and I would like to make sure that files that have the same name as already uploaded files do not replace them.

So I would like to create a unique ID for each uploaded file. Is this achievable through my PowerAutomate flow?

You can create a compose action with the below code. It transforms the date to unix format (just numbers) and after attach it to the file name
div( sub( ticks( utcNow() ), ticks( parseDateTime('1-1-1970') ) ), 10000000 )

Hey @earribasb thanks for your suggestion!
I tested it but it seems like when files are uploaded quite quickly, they'll get the same ID...

although datetimestamp is usually reliable, but if your use case will have file being uploaded at exact same moment - then you can use guid() expression in power automate to append to your filename.
