上传后重命名或删除客户端计算机上的文件

Question

Hello I have a couple of questions.

-Is there a way to be able to either delete or rename a file on the client’s machine after he uploads the file via a file upload control to the server.

-This one is closer to a question that I asked before ( link ), would you be able to get the path of a uploaded file or move the uploaded file on a client’s computer if the client has IE Trusted Sites Security Zone for your website.

The overall problem is that Clients are uploading many files to a website. Once the file is uploaded it needs to be clear on the client's computer that the file already has been uploaded once so that they do not miss or re-upload the same file. If the file has been renamed, moved, or deleted upon upload then it would be difficult for them to miss or re-upload a file.

Answer 1

No, you cannot delete files from the client's machine ( not without some type of extension or parallel software running on the machine ). I would instead encourage you to consider another route. When multiple files are selected for upload, you have access to their file names and file sizes via JavaScript:

fileupload.addEventListener( "change", function () {
    console.log( this.files ); // FileList {0: File, 1: File, 2: File, length: 3}
});

I would suggest you send this list of details over to a server-side script that inspects them against a history of uploads from the current user. If matches exist, you can relay that information back to the user and allow them to modify their list of files to upload.
