Hello @rahul1231

I don't know how you can determine which PPT file is corrupted or not.
Are there any error output while converting it to PDF format?
Or does the conversion process not complete forever?

If any of your PAD actions will fire error message, then you can use "On error" options located at the left bottom corner of action parameters settings window.

You can set "On error" options such like "Run subflow" or "Go to label". Therefore, you can create sub process that is executed only when an error occurs.

For the "file convert process is never ending" scenario, I suppose you can use "Fail with timeout error" option to be failed after the specified number of seconds in "Duration".

I hope above is helped you.
Thank you.

I'm also curious as to why the files get corrupted.
I've experienced something similar when closing an application while it was saving a file. If that's the case, perhaps inserting a wait before closing the application, could avoid the initial corruption.

let me elaborate.
If I upload a corrupted ppt then the whole power automate script gets stuck because it cannot save that file or sometimes it cannot open that ppt file. So to identify that the script is stuck and move that particular ppt to another location from the source location(for power automate), so power automate can move to the next ppt to work with.
This I need.

Wrap the failing part in an "On block error", which runs a sub flow, handling the error. Eg. moving the file and rerunning the upload flow.

If you want more advise, you'll have to provide more information - screenshots, what actions fail, what happens before, what happens after and what is the desired outcomes.

Yes, that's what I wrote. Please provide a screenshot of your process..

Inserting an "On block error" is done by dragging it into the process, wrapping your actions and adding a "Run subflow"-rule. The subflow should contain the error correcting steps - which is dependent on your desired outcome and initial steps. To assist further, I'll need more info from YOU.

A big thanks @Daniel_Pa and @Anonymous. I did it. made an onblockerror that connects to a subflow. if I run the script manually it is working just great. but the weird thing is from the cloud scheduler it cannot move the file. The weirdest part is a part of that subflow is working but not the moving part.
so manually running is fine but not from the cloud scheduler.
Help....!!!!!!!!!!!!!!

Hello @rahul1231

Please tell us more about the file storage your flow is using to read from and write to.
Local harddisk? File share network drive? Cloud storage such like OneDrive?
Also, have you checked the applied permissions for source and destination directory?
When you run the flow from cloud scheduler, which user account is used to access those file storage?
Do you see any error messages?
You said "it cannot move the file", but exactly what is happening while the flow is trying to move the file?
How long did you wait to determine that the flow was failed to move file?

Thank you.

Hi,
it is a File share network drive. a mount point. where I have created a folder.
I have checked the applied permissions. it has full control for everyone.
I checked the error message from the cloud activity. It is saying: Problem while executing action 'Move'. Destination folder doesn't exist.
I have put wait 3sec and 4sec.
note: I have created a folder on the desktop instead of the mounted drive. It's the same thing.

Hello @rahul1231

It sounds like you may be specifying a path in a format that cannot be referenced from other environments.
How about trying to specify the destination folder in a path in UNC format?

Thank you.
