Unique File Naming Solutions for document libraries
I have a document library with a excel custom template. When my user's save a document, I'd like to guarantee that the filename is unique...when the document is SAVED. how to accomplish this? A workflow is not an option.

I guess, you could have an event handler. After you upload the document, you could do an item adding event handler which could verify if the document with that particular name exists. If it does, you could make it unique either by adding a GUID or prevent it from adding and allow users to change the title before uploading. Hope this helps.V

Hi, Alternatively, you can add columns to the library by way of recording metadata, thus empowering user to not simply uploading a file. hth,Chirag Patel, MCTS @techChirag techChirag.com

Hi, There is no real guarantee to have a unique filename, other than creating additional columns to describe the properties of file content. Another alternative is, by default, document library has an ID field you can just modify the view to include this ID column in display. That way the user can still see two identical filenames but with different ID. hth,Chirag Patel, MCTS Blog: techChirag.com Twitter: @techChirag

Please refer to the following URL, you can write an event handler similar to this to prevent duplicate file name in your document library. http://sharepointserved.blogspot.com/2011/06/prevent-duplicate-field-name.html--Cheers
