• Capture folder structure. Snap2HTML recursively scans selected disk drives or directories and records the entire folder and file hierarchy. The process preserves parent-child directory relationships while maintaining the exact file system structure.
• Generate standalone HTML. The application creates a single HTML file that contains all the folder structure information. This document includes both the data and the JavaScript code necessary for interactive viewing, with no external dependencies.
• Collapsible tree navigation interface. The output presents an interactive tree view where users can expand and collapse sections of the directory. This functionality facilitates exploring large folder structures.
• Integrated search. The generated maps include a search field that allows quickly locating files and folders by name. Results are filtered in real time as the search term is typed.
• Detailed file information. For each item, the name, size, modification date, and attributes are displayed. File sizes are shown in bytes and with readable formats (KB, MB, GB).
• Customizable visible columns. Users can configure which information columns they wish to display in the final view. Options include name, size, modification date, and file attributes.
• Attribute-based filtering. It is possible to filter the view to show only files with specific attributes such as hidden, system, or read-only. This feature helps focus on particular types of content.
• Export to CSV format. In addition to the HTML format, the application can export the folder structure information to CSV files. These files can be imported into spreadsheets or databases for further analysis.
• Command-line execution. Snap2HTML offers a command-line interface for automation via scripts. Parameters allow specifying the source folder, destination file, and configuration options.
• Portable mode with no installation. The application runs as a standalone executable that does not require installation on the system. It can be run directly from USB drives or temporary folders.
• Support for network drives and NAS. The tool can map folders located on network resources and NAS drives, provided the operating system has appropriate access permissions.
• Statistics display. Provides summaries with quantitative information such as total number of files, number of folders, and total size of the scanned space.

Snap2HTML was created by Roger Ljung of RL Vision. Development began in 2013 as a complementary tool for system administrators and users needing to document directory structures. The program is written in Delphi, an object-oriented programming language. The first public version was released in October 2013. Subsequent updates have added features such as CSV export, a command-line interface, and user interface improvements.
