Hello, I want to open a local file in my C:\ drive when clicking a button in D365FO.

I'm in tier-1 environment

I tried to use browser.navigate function to open in a browser but it didn't work, it was giving pop up errors.

Even I tried to access the file directly to open it, and also it didn't work.

Seems like the D365FO can't read my local C:\ drive.

Can someone help.

Hi @CU09091357-0

Are you fixing the file name and location, because if its interactive anyway (click of a button) you could use the file upload control or the file upload dialog File::GetFileFromUser()

Take a look at this post: https://community.dynamics.com/blogs/post/?postid=7a67400d-c28b-4080-bace-b7f02c834695

Thanks

Anthony

First of all, your URL is wrong. You can't use the local path (C:\Attachments\file.pdf) as a URL; you must use the file URI scheme instead (e.g. file:///c:/Attachments/file.pdf). Please test the URL before continuing.

But as I remember, such URLs don't work in Browser.navigate(). You'll need to look for a different solution. What about storing the files directly in the database (and avoid both this topic about local files and your problems with the Azure storage emulator)?

Martin Dráb I'm in my local environment, I'm using it as data archive.

The attachments are not accessible because we don't have their metadata in the local emulator (127.0.0.1:10000), and we tried everything but nothing is working.

I have all the attachments downloaded in my C:\ drive.

I'm using the approach of opening a new tab with url: C:\attachments\filename (which is the fileid that I will take from the docuvalue table when I click the button that I created and wants to write the code that opens me a new tab inside), so the file open.

Please give us more details than just repeating that you want to open a file.

Do you mean that you assume that every user's computer has C:\Attachments\file.pdf (which sounds like a strange assumption to me) and you want to open the file by the web browser or a default application for PDF files? If so, we should ignore the remark "the D365FO can't read my local C:\ drive", because the requirement is not about reading any files in F&O, right?

Hi @CU09091357-0,

As far as i know, you can't access files on a local machine since D365fo is a web application. in this case, so i suggest you use power automate to retrieve your files through a connector (on-premises data getway).

Best regards,
