How the new Edge will handle file:// URI ?
SoumyaRaju - See the full resolution of the case below:
Cause:
The deprecation of file:// protocol links in Edge is by design. It has been inherited from the Chromium project and it is an expected behaviour that file protocol links are not open in Edge, for security reasons. There are other implementations that also allow the sharing and access of files without resorting to the File protocol, which has security risks associated with it: https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftextslashplain.com%2F2019%2F10%2F09%2Fnavigating-to-file-urls%2F&data=02%7C01%7Cdamatos%40microsoft.com%7C7fd6364cc7254cd987d208d7ec483d88%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637237667351409534&sdata=JA%2Bj4%2FOGMbYmyMmJZawxXoLKNXyzi5aZLrvURLaSkBw%3D&reserved=0.The lack of a warning or error message from Edge to the user when such a navigation is blocked has been acknowledged as a bad user experience which can lead to confusion and misunderstanding of this as an expected behaviour. As such, it has been flagged a bug that should be fixed in the future.
Resolution:
The short-term solution is to render the affected page in IEMode, where the issue does not occur. The longer term solution is to replace the URLs on the page or fully replace the page with Sharepoint, given that it is particularly geared towards this type of implementation.
