here’s a simple example of how you might set up a controller and view to delete a file in an ASP.NET MVC application. using System.IO; using System.Web.Mvc; namespace YourNamespace.Controllers { public class HomeController : Controller { public ActionResult DeleteFile(string fileName) { string filePath = Server.MapPath("~/YourDirectory/" + fileName); if (System.IO.File.Exists(filePath)) { System.IO.File.Delete(filePath); ViewBag.Message = "File deleted successfully."; } else { ViewBag.Message = "File not found."; } return View(); } } } In this controller, there’s an action DeleteFile that takes a fileName as a parameter. It constructs the file path, checks if the file exists, and if it does, deletes the file. The result of the operation is stored in ViewBag.Message . View (DeleteFile.cshtml): @{ ViewBag.Title = "Delete File"; } @ViewBag.Title @ViewBag.Message you can create a link in your view that triggers the DeleteFile action when clicked. Here’s an example: @Html.ActionLink("Delete File", "DeleteFile", "Home", new { fileName = "YourFile.extension" }, null) Thanks

public ActionResult DeleteFile(string fileName) { // Your uploaded file folder directory string folderPath = Server.MapPath("~/Uploads"); // Create combinpath of folder and filename string filePath = Path.Combine(folderPath, fileName); try { // Check if the file exists or not using File.Exists method if (System.IO.File.Exists(filePath)) { // Delete the file using File.Delete method System.IO.File.Delete(filePath); // return a success message or custom message you want to return return Content("File deleted successfully"); } else { // File does not exist message incase file not exists on folder return Content("File not found"); } } catch (Exception ex) { // Handle exceptions, log errors, or return an error message from here return Content($"Error deleting file: {ex.Message}"); } } add link to delete in .cshtml @Html.ActionLink("Delete File", "DeleteFile", "File", new { fileName = "FileNameToDelete.txt" }, null)

You can use string directory = @"C:	emp"; string filename = @"readme1.txt"; try { File.Delete(Path.Combine(directory, filename)); } catch (IOException ex) { WriteLine(ex.Message); }

To delete an uploaded document from a folder directory in an ASP.NET MVC project, you can use the System.IO.File class to perform the deletion operation. Here's a simple example of how you can achieve this: using System; using System.IO; public class FileOperations { public void DeleteFile(string filePath) { if (File.Exists(filePath)) { File.Delete(filePath); Console.WriteLine("File deleted successfully."); } else { Console.WriteLine("File not found."); } } } In your controller or service class, you can call the DeleteFile method by passing the file path as a parameter to delete the uploaded document from the folder directory.

When a user or staff member uploads a file, one technique to handle multiple file extensions is to first save the filename together with the extension in the relevant database table. When deleting the file, retrieve the same and use it. If you decide you no longer need the folder, you can delete it. Make sure you won't be impacting any functionality that depends on the contents of that folder, though, before proceeding. Before deleting a folder, always create a backup in case you need to restore it later. To make sure that the deletion won't result in any problems, think about speaking with your team or a more knowledgeable developer if the folder is a part of a bigger project.
