All about WL Files

The WL file type is primarily associated with Wolfram Mathematica.

WL	File extension: WL
	File type:	versatile text file

What is a WL file

WL files mostly belong to Wolfram Mathematica. WL files may represent a number of specialized data formats. In many cases, these files appear as Wolfram Language source files used in Wolfram Mathematica for coding, datasets, or graph structures. However, the same extension is also used in other fields.
For example, some WL files are used as:

• DICOM Worklist Files – These files, sometimes containing a DICOM image or related metadata, are used by imaging tools such as ImageJ (ImageJ).
• Wordlist/Playlist Files – In other cases, the file may hold a list of words or media links, such as those used in Winamp.
• Financial Watchlist Files – These versions store financial instrument data and are used by trading platforms like MetaTrader 5 (MetaTrader 5).
• Audio or Markup Files – Some WL files contain wavelet compressed audio or serve as wireless markup language files, with links to applications such as Winamp and WinSQL Lite (Winamp).
• Web Browser Log Files – A few are formatted in HTML and record download or log details (Dahsing).

FilExt.com tips: If you find a WL file on your PC, a good starting point is to open it in a text editor (like Notepad++). This will help you see if the file contains programming syntax (pointing to Wolfram Language code), DICOM headers, or other clues. Once you identify the format, use the corresponding software to view or run the file.

How to open a WL file

You need a suitable software like Wolfram Mathematica to open a WL 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 WL file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a WL file directly in the browser:. Just drag the file onto this browser window and drop it.

WL file format:

To find out what program is needed to open WL files, you need to determine the file format. The file format can be determined based on the file extension and the signature (the first few characters of a file). If the file extension or signature does not match the file format, errors will occur when opening or editing the file. When there is a problem with a file, the first step to solving it is to determine the file format. Below is our analysis of the WL files:

The WL file ending has no uniform or dominant file format. The file formats most commonly found in WL files are:

• 20% of all WL files use the same file format, which can be identified by the letters "´´´´´´ ´´´´´´´´ ´´´´´´´´´´ ´`´` ` `` `" at the beginning. If you open these files in a text editor, you can view and read the content yourself. The file size is in the range of 1 GB to 4 GB. The file type was developed only in the last few years. Several words can almost always be found in the files, e.g. ``````, ``````` and ````````. A common filename is breachcompletion_sorted.wl. Files like these are about breachcompletion and sorted.
• 20% of all WL files start with the magic bytes 28 2A, which are always the first bytes of this file format. These files are text files and can therefore be read using a text editor. The average file size is 5 KB with most files being between 650 bytes and 21 KB in size. The keywords (* ::Package:: *) are typical for these files. A usual file name is GR.wl. Files like these are sometimes connected to export and plot.

All other WL files (60%) have different formats, the following 7 formats can be found: DICOM, HTML, UTF-8, WMAP and Dataset. Often described as bank, network, built or watch. Just click the "Choose your .wl file to analyze" button on this page to find out what your WL file is.
