Hi @rkgoriparthi ,

The file size can only be judged after the user uploads it.

If the file size is 0KB, delete the file, otherwise keep it.

I assume you save the attachments to the attachment column in list.

I did a test for you.

1\ This is my flow 'Test50'.

Id: Ask in powerapps

Value:div(int(length(string(outputs('Get_attachment_content')?['body']))),1024)

2\ Set the submit icon Onselect property to:

SubmitForm(your form);Set(A,Test50.Run(your form.LastSubmit.ID,your form.LastSubmit.ID).thevar3)

3\ Add a label control and set its Text property to:

A

Hi @rkgoriparthi ,

This is impossible. Just using powerapps can't meet your requirements.
