Link to a document in a document library when the document is stored/Updated in document library
Follow the below steps to do Link to a document using OOTB.
We use the Content Type “Link to a Document” to link to a document that could be stored in another document library.
If the document library where you want to use the “Link to a Document” hasn’t been setup to use Content Types, you’ll have to click Settings, Document Library Settings, there you’ll need to access the Advanced Settings.
We need to add a Content Type, but before we can do this we’ll have to tell our Document Library that it can make use of different Content Types. Select “Yes” for the “Allow management of Content Types“.
When you return to the Document Library Settings, you’ll see a new section called Content Types, this is where we’ll add a new Content Type, click “Add from exisiting Content Type“.
The content type we need is “Link to a Document“, add it here.
When you return to your Document Library and click new, you’ll see that you have a new option to choose from, “Link to a Document“.
Let’s make a link to a Document in another Document Library, click “Link to a Document”. You’ll have to enter a name for the Link and enter the path to the Document you want to link to.
After confirming this is what your link looks like.
We made link to a document that’s saved in another document library, whenever you make a change to the master document, you don’t need to worry about the link, it will point to the changed document.
In the same way we can put "link to a document" links in another folder with in the Documnet library using Object Mode, Here i am using Event handler to Create Link to document when new item is Added in Document Library
