As far as I know, opening something with Windows Explorer from a browser link was only possible in some Internet Explorer versions (or if you are running an html file locally on your computer).
Sharepoint for instance had this feature out of the box and it worked in IE.
Would be surprised if Chrome for instance allowed this behaviour.
Here are some methods that might work:
Figure out how to construct .lnk files (shortcut files).
They are not readable using notepad or similar, you would need a tool for this sort of thing to figure out the structure.
If successful, downloading a .lnk file and running it should not alert security functions.
Make AwareIM download a html document containing a link to the folder location
Example code how the a href looks like: https://www.geeksforgeeks.org/how-to-make-an-html-link-to-open-a-folder/
This should not be a security problem since the HTML file is run from your local drive.
The steps would look something like this:
- Click the link.
- Wait for html file to download.
- Run html file, it will open in new tab.
- Click the link.
- Voila, maybe.
Display the file path as a field that is easy for the user to copy, then they can paste it in the Windows Explorer address field
Perhaps this is what you have right now. You could even make a javascript copy button that copies the path to the clipboard.
Lower security settings in your browser or use plugins to allow linking to local drive folder locations
A bad idea but it might also work.
