File manager asp net


ASP.NET is a popular programming language used for web . One common in web development is the ability to manage files on the server. In this article, we will explore how to implement a file manager in ASP.NET, allowing users to upload, download, and delete files.

Setting up the File Manager

To begin, let's a new ASP.NET project and add a file manager page. We can use the FileUpload control to allow users to upload files, and a GridView control to display the list of files on the server.

Uploading Files

When the user clicks the “Upload” button, we need to handle the event and save the file on the server. We can use the FileUpload control's PostedFile property to access the uploaded file and save it to a specified location.

protected void btnUpload_Click(object sender, EventArgs e)
    if (fileUpload.HasFile)
        string fileName = Path.GetFileName(fileUpload.FileName);
        string filePath = Server.MapPath("~/Files/") + fileName;

Downloading Files

To allow users to download files, we can handle the click event of the “Download” link button. In the event handler, we can use the object to send the file to the user's browser for download.

protected void lnkDownload_Click(object sender, EventArgs e)
    LinkButton lnkDownload = (LinkButton)sender;
    string filePath = lnkDownload.CommandArgument;
    string fileName = Path.GetFileName(filePath);
    Response.ContentType = "application/-stream";
    Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName);

Deleting Files

To delete files from the server, we can handle the click event of the “Delete” link button. In the event handler, we can use the File to delete the specified file.

protected void lnkDelete_Click(object sender, EventArgs e)
    LinkButton lnkDelete = (LinkButton)sender;
    string filePath = lnkDelete.CommandArgument;


In this article, we have explored how to implement a file manager in ASP.NET. By the FileUpload control, GridView control, and events for uploading, downloading, and deleting files, we can provide a user-friendly file management system in our web application.
