DiskExplorer X

Visualize file system structures

DiskExplorer X

Runtime's DiskExplorer X (formerly "Disk Digger") lets you inspect and navigate any file system or on-disk structure. Details are displayed in an Internet Explorer window. Scripts and an integrated script interpreter generate DiskExplorer X views. The customizable scripts determine what information will be displayed and how. The script language is Pascal, so everybody with knowledge of a higher programming language will be able to modify existing or create new scripts.

Write Your Own Data Recovery Software

At Runtime Software, we use DiskExplorer X to reverse-engineer file systems and program new features for our data recovery software. You can employ DiskExplorer X for research or forensic investigations when exploring unknown hard drives. 

DiskExplorer X

DiskExplorer X: MFT entry View of sector 7088128 on HD128

The provided DiskExplorer X scripts show you how to extract files programmatically from NTFS, FAT, EXT, XFS, HFS+, and APFS. You can use these scripts as a blueprint for customized data recoveries or forensic investigations.

You can write additional scripts for other file systems or container structures such as backup files, virtualization volumes, encrypted volumes, or surveillance disks. A rich set of built-in commands lets you access and process disks and images files. You could even develop your own data recovery software based on those scripts.

If a standard recovery software, such as GetDataBack, is not sufficient to accomplish your objective, DiskExplorer X is the perfect tool.

You can create report scripts for data recovery or forensic purposes that no other software offers.

Internal Working

DiskExplorer X consists of two distinct functions,

  • a script interpreter for retrieving and formatting the desired information from the inspected disk or image, and  

  • an Internet Explorer instance for rendering the script's output to the screen.

The Explorer address bar tells the program the drive, sector, and View to be displayed. For example, the address


tells DiskExplorer X to display the content of sector 7088128 on the first physical drive (HD128:) using the script mft.src.

The script editor contains a powerful debugger. You can trace through your script, inspect its flow and variables.

Scripts usually contain many links allowing the user to navigate through the file system as she would navigate a Web site.

The usage of Internet Explorer enables you to print your windows effortlessly. You can also save the current View or all visited Views into HTML documents. This facilitates documentation of, for example, forensic jobs.
