What is an SK file?

The SK file extension is primarily associated with vector drawings created by Skencil (formerly known as Sketch), an interactive vector drawing application for Linux and Unix-like systems. The format relies on the Python programming language for its object definitions, allowing for the storage of Bezier curves, rectangles, and ellipses. Historically, the format was notable for its integration with the LaTeX typesetting system and its use in the open-source graphics community prior to the dominance of SVG.

How to open an SK file

Opening SK files requires the legacy Skencil application running on a Linux-based environment. Modern support is scarce; however, the sK1 vector graphics editor (a fork of Skencil) maintains partial compatibility. Users attempting to access SK files on Windows or macOS generally require file conversion utilities to transcode the Python-based vector objects into standard formats such as PDF, EPS, or SVG.

What is a WMF file?

Windows Metafile (WMF) is a 16-bit graphics file format originally introduced in Windows 3.0 (1990) to store a sequence of Graphics Device Interface (GDI) function calls. Unlike pure bitmaps, WMFs contain instructions for drawing vector lines and circles, though they can also encapsulate raster images. The format suffers from device-dependence and lacks the color handling capabilities of its 32-bit successor, Enhanced Metafile (EMF), leading to its deprecation in modern development.

How to open a WMF file

Due to its legacy status, WMF is natively supported by the Windows Picture and Fax Viewer and Microsoft Paint. For professional editing and conversion, vector graphics software such as Adobe Illustrator, CorelDRAW, and Inkscape (using UniConvertor) is recommended. On Linux, the libwmf library enables support within the GIMP and ImageMagick suites.
