What is a .PSB file?

A .PSB file is a type of image file specifically used and created by Adobe Photoshop, which is a widely-used professional software for editing images. The "PSB" stands for "Photoshop Big," and this format is designed to support extremely large images. Specifically, it is used for images that exceed the size limits of the standard Photoshop document format (.PSD), which are 30,000 by 30,000 pixels or a file size of 2 gigabytes.

The .PSB format is very similar to the .PSD format in that it can store an image with layers, allowing for detailed editing and composition in Photoshop. However, because .PSB files are intended for larger images, the file sizes can be significantly larger than typical .PSD files.

To open a .PSB file, you can use several programs: 1. **Adobe Photoshop 2023**: This is the primary software for which the format was developed. Photoshop supports all features of .PSB files, including editing layers, colors, and other image properties. 2. **File Viewer Plus**: This is a versatile file viewer that you can download from the Microsoft Store. It allows you to open and view the content of .PSB files, although it might not support editing all aspects of the file as extensively as Photoshop. 3. **VLC Media Player**: While primarily known as a video and audio player, VLC can also open and display .PSB files. However, its functionality with these files is limited to viewing rather than editing.

When working with .PSB files, it's important to have sufficient storage and processing power, as their large size can demand significant computer resources. These files are typically used by professional graphic designers and photographers who need to work with very high-resolution images or complex digital art projects.
