GPSCAN Files: Storage for GrandPerspective Scans

GrandPerspective is a disk space visualization utility developed by Erwin Bonsma. GPSCAN files are essential for this software, as they store scan data generated by GrandPerspective’s analysis of a user’s storage device. These files capture the hierarchical structure of the scanned device, along with details about the size and location of files and folders. GPSCAN files enable GrandPerspective to quickly visualize the distribution of disk space, providing users with valuable insights into their file systems.

GPSCAN files are binary in nature, utilizing a proprietary format designed specifically for GrandPerspective. They encapsulate the results of a scan, including the names, sizes, and paths of all files and folders on the analyzed device. This data is efficiently stored in a compact format, allowing for quick retrieval and processing. GPSCAN files serve as a snapshot of the disk space usage at the time of scanning, facilitating comparisons over time and enabling users to track changes in their file systems.

Understanding GPSCAN Files

A GPSCAN file is a proprietary binary file format used by GrandPerspective, a file and disk space visualization tool for macOS. It contains a snapshot of a specific file system, including information about the directory structure, file sizes, and file types. GPSCAN files can be used to quickly visualize and analyze disk space usage, identify large files or folders, and perform file cleanup tasks.

Opening GPSCAN Files

GPSCAN files can only be opened and viewed using GrandPerspective. To open a GPSCAN file, launch GrandPerspective and click on the “File” menu. Select “Open” and navigate to the location of the GPSCAN file. Once the file is opened, GrandPerspective will display the file system snapshot, visualized as a color-coded treemap. The treemap provides a graphical representation of file sizes and their distribution across the file system.

GPSCAN File Structure

GPSCAN files are XML-based files that store the scan results of directories and files using GrandPerspective. They contain information about the size, name, and path of each scanned item. GPSCAN files also include metadata about the scan itself, such as the date and time it was performed, the version of GrandPerspective used, and any additional settings or filters that were applied.

GPSCAN files are organized into a hierarchical structure that reflects the directory structure of the scanned file system. Each directory is represented by an XML node, and each file is represented by a child node of the corresponding directory node. The size of each item is stored in the “size” attribute of the node, and the name and path are stored in the “name” and “path” attributes, respectively.
