What is a CURL file?

CURL files mostly belong to cURL. CURL files are plain text files that store HTTP request commands. These files contain the parameters needed to perform a web request using the cURL command-line tool.
How they work:

Command storage: They include information such as the URL, HTTP method, and headers required to execute a network call.

Automation: They allow you to save and reuse a complete HTTP request, which can help in automating repetitive tasks.

Editing and debugging: Since they are text files, you can open them with any basic text editor like Notepad or VS Code to modify the request details.

The files are linked to the official cURL project. For further technical details and usage examples, visit the official cURL website.
FilExt.com note: Few users know that a properly structured CURL file can reproduce complex network requests, including custom headers and parameters, making it easier to troubleshoot network issues or replicate specific web interactions.

How do you open CURL files?

You need a suitable software like cURL to open a CURL file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your CURL file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CURL file directly in the browser:. Just drag the file onto this browser window and drop it.

CURL file format:

If you can determine the file format, the associated program can also be determined. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the CURL files:

As a file extension, CURL isn't very common and is mainly used by one program with a specific format. However, the following two file formats are common:

75% of all CURL files start with the magic bytes curl , which are always the first bytes of this file format. These files contain text and words, not binary data. The file size is in the range of 210 bytes to 49 KB. This file type is new and state-of-the-art. The keywords https, POST, application, Content-Type, --header, curl --location, json and request are typical for these files. Some examples of file names are test.curl or curl.curl. Such files are related to downloader, zinc, request, create, generate, mobile and token.
4% of all CURL files are based on the popular ELF file format. ELF is the abbreviation for Executable and Linkable Format and is the standard binary format on Linux and Unix. These are binary files, so they do not contain words or text. The average file size is 1 MB with most files being between 210 KB and 1 MB in size. An example of a file name is curl..

All other CURL files (21%) have different formats. These files sometimes refer to index. If you want to find out which format your CURL file belongs to, just click on the button "Choose your .curl file to view".
