Some applications define their own URI schemes for internal use, such as:

To fetch a URL file in code, you'll typically use a library or built-in function provided by your programming language or framework. Here are some examples:

While standard browsers block it, there are specific environments where fetch('file:///...') does work:

Let’s split the string into its visible components: fetch-url-file-3A-2F-2F-2F

If we apply standard percent-decoding to 3A-2F-2F-2F, we get :/// (colon, three slashes). So the full decoded string becomes:

fetch-url-file:///

That is still unusual. A typical URL includes :// after the scheme (e.g., http://, ftp://). But here we have three slashes — which sometimes appears in file URIs (file:///) or in obscure application-specific protocols. Some applications define their own URI schemes for

Thus, the most plausible interpretation is:

fetch-url-file:/// – A custom URI scheme or malformed URL where the “scheme” is fetch-url-file, followed by three slashes (an absolute local path indicator, similar to file:///etc/passwd).

When fetching URL files, keep the following best practices in mind: If we apply standard percent-decoding to 3A-2F-2F-2F ,

Fetching a URL usually involves making an HTTP request to the specified URL. This can be done in various programming environments. Below are examples in JavaScript (using modern browsers or Node.js), Python, and curl.

Fetching a URL file involves several steps:

If you identify where the string is generated, ensure you are not double-encoding or mis-encoding URLs. Use standard libraries:
