Duplicating filename issue
<p>I have a web page in which different user account can be created and the files created for individual user will be diaplayed in the gridview. That is, The files created by abc will be displayed in gridview when abc logs in. Whenever a user creates a file, these files are stored in a folder so that whenever the user clicks on the filename in the gridview the control goes to this folder to open it. So now my question is how can I manage the duplication of the filename. that is, If the user abc creates a filename "Lion", this will be stored in the folder and also in the database and will be displayed to abc when he/she logs in. Now another user say xyz wants to create the the same filename "Lion" which is going to store in the same folder, then that file created by abc will be replaced by the one created by xyz. How can I avoid this?</p>
