Posted on by arindamsarma

A flow has been prepared in such a way that all the attached files through the outlook mails are saved in a specific folder of SharePoint site and it is working fine. But the size of all the saved file is becoming 4 bytes. as a result none of the files are opening.

Any email arrives.

Attachment is copied to a specific SharePoint folder.

All the files are saved with a fixed size of 4 bytes.

Please guide me with a solution.

Hi @arindamsarma ,

I recommend you switch to classic designer and test again. The file created in new designer can't open sometimes.

Hi @arindamsarma ,

It's wired.🤔 In my test, I add a Get attachment action and use name and content from it to create file, the file can be opened. I am looking for what is the difference cause this problem. I recommend you try this first.

Hi @arindamsarma ,

You can add name manually instead of using dynamic content.

Note: Don't forget file extension.😀

Yes, how to manage extension, because name of the file can be anything but the extension should be the same as the original file. Please suggest if there is any function to identify the exact extension of the original attachment file.

Hi @arindamsarma ,

You can use split to get file extension.

concat('.',last(split(<dynamic value>,'.')))

Above expression can get '.pdf', '.docx', etc.

Can I get the dynamic value from the dynamic content directly?

Hi @arindamsarma ,

Of course, the <dynamic value> in my provided expression just an example, it stands for file name you can get in the flow. You can replace it with dynamic content which is file name with extension.
