We can find many articles related to file upload, view, download, etc. This article is written on this basic concept of uploading and managing files. File upload is a process of copying the file from your machine to the remote server. Other users of the system then share this file by viewing / downloading. What happens when I upload a file that already exists in the remote folder to which you are uploading? While discussing this problem, various other issues arises, such as:
- Should the program allow the user to restore this file or retain the existing file?
- If the file exists, then should I copy the file as a new version?
- How do I manage files if the user uploads files of same name and type more than once?
This article gives you a solution for all the above problems and also I hope this article will be useful for you to integrate in your projects.
