How Can I Get the Full Local File Path from a Browser File Input?

Getting the True Local File Path from Browser File Inputs

Browsers often display files selected through as originating from "C:fakepath" or similar fake locations. This security measure prevents scripts from accessing the actual local path, a practice that could be abused for malicious purposes.

This limited information can be frustrating when developers need the full local path for file processing or other operations. While there is no direct way to retrieve the true path in modern browsers, there are workarounds that can provide a partially accessible representation.

For Mozilla-based browsers (e.g., Firefox), accessing the file's full path is not possible. The browser will only display the file's name as "test.csv" in the specified element.

However, in other browsers, developers can use the webkitRelativePath property (WebKit-based browsers like Chrome) or mozFullPath property (pre-Firefox 69) to obtain a partial local path representation.

Here's an example for Chrome:

`

  document.querySelector('input[type=file]').addEventListener('change', function() {</p><pre class="brush:php;toolbar:false">console.log(this.files[0].webkitRelativePath);

});

`

This code will log a path like "Documents/test.csv", which is not the full path but provides a more informative representation than "C:fakepath".

It's important to note that these workarounds may not be available in all browsers or may have security restrictions in place. Hence, it's crucial to consider the security implications of accessing file paths and adhere to browser security guidelines when developing web applications.
