Welcome to DROID | License | Frequently Asked Questions

DROID 6 has many new features which improve the speed, accuracy and your exploration of its results. Behind the scenes, it introduces some new capabilities to allow signatures for new file formats to be developed more easily, and with greater power to match difficult file formats.

- Speed
- Accuracy
- Reporting
- Exporting
- Filtering
- User interface
- Container signatures
- Binary signature syntax

### Speed

- A new binary signature recognition engine is approximately twice as fast as the old engine, and with an enhanced syntax offering new kinds of signatures.
- An option to limit how much of a file is scanned from its beginning and end.
- New profiles are quicker to start up, using copies of pre-built empty databases, rather than creating them anew each time.
- Profiling tools were used to locate and eliminate bottlenecks. In particular, binary signature recognition and archival file handling is now much faster.

### Accuracy

- An option to choose how file extensions are matched.
- A new type of signature for file formats which are not recognised well using the existing engine.
- Enhancements to the binary signature syntax allows for more powerful binary signatures to be developed in future.
- DROID can now process 64-bit zip files.

### Reporting

- A new reporting engine offers 11 predefined reports, giving statistical breakdowns of your files and folders in various different ways.
- Reports can be viewed on screen, and saved into several different file formats, including PDF, text, web pages and XML.

### Exporting

- CSV files can now export results one row per file, or one row per format identification.

### Filtering

- Filters can now be saved and loaded for quick access to commonly used filters.

### User interface

- Icons are used to communicate essential information quickly.
- Filtering can be turned on or off from the main toolbar, via the Filter On checkbox.
- Folders and archival files which are filtered out in the main view appear greyed out, to distinguish them from items which were not filtered out.
- If a file has multiple identifications, its format information is now directly accessible from the main window.
- "Open Containing Folder" option to go straight to the files you have profiled from within DROID.
- A right-click popup menu offers common editing options quickly.
- Copy to clipboard for results in the main window.
- "Expand" and "Expand next three levels" options for selected results in the main window.
- General tidying up to maximise the use of screen space.

### Container signatures

- Container signatures are a new kind of file format signature, to recognise file formats which contain other files inside themselves (for example, Microsoft Office 2007 files).

### Binary signature syntax

The syntax of the signatures used by the binary signature engine has been enhanced, both in terms of readability and fundamental expressivity. In addition to existing syntax, it allows for text strings, case insensitive text strings and arbitrary sets of bytes. These features can be mixed together in ways which the previous engine cannot process. This makes it easier to create new signatures, and to understand existing ones. In some cases, several old signatures can be combined into one signature, which increases the speed of DROID.

The new syntax will be documented in other technical documentation, and will not appear in signature files for some time until users of DROID have updated to the newer engine. Some of the new syntax can be seen in the container signature files, which do not have backward compatibility issues.
