What is a VSSM file?

The VSSM extension denotes a Microsoft Visio Macro-Enabled Stencil file, introduced with Visio 2013 to store reusable master shapes alongside embedded Visual Basic for Applications (VBA) code. Adhering to the Open Packaging Conventions (OPC), it functions as a ZIP container holding XML data structures for shape geometries and binary parts for compiled macros. Security policies often flag this format due to the potential execution of arbitrary code via the embedded VBA scripts.

How to open a VSSM file

Opening VSSM files requires Microsoft Visio Pro or Standard editions with macro security settings adjusted to permit VBA execution. While LibreOffice Draw can parse the vector shape data within the stencil using reverse-engineered libraries, it cannot execute or edit the proprietary VBA macros contained within the binary sub-parts of the archive.

What is a JPG file?

JPG is functionally identical to the JPEG format, differing only in the file extension length, a legacy constraint from the MS-DOS 8.3 filename limit (which allowed only three characters for extensions). It implements the same ISO/IEC 10918 standard, using lossy compression based on Discrete Cosine Transform (DCT) and Huffman coding to store photorealistic images. The file structure contains markers such as Start of Image (SOI) and End of Image (EOI) and supports color spaces like sRGB and CMYK, making it interchangeable with .jpeg files in all software contexts.

How to open a JPG file

As one of the most ubiquitous file types in computing, JPG files open natively on Windows, macOS, and Linux without external software. Default viewers like Microsoft Photos, Apple Preview, and Linux image viewers handle the format automatically. For editing or conversion, industry-standard tools including Adobe Photoshop, Paint.NET, and XnView provide extensive support. Web browsers universally render JPGs without plugins.
