Announcing New File Type Sample Files

February 5th, 2014 No comments

UT San Antonio has kindly provided digitalcorpora with open source, publicly releasable samples of 32 file types. These are the samples that were used by Dr. Nicole Beebe to develop the Sceadan File Type Classifier.

Included file types are ASP, AVI, B64, B85, BZ2, CSS, DLL, ELF, EXE, EXT3, FAT, FLV, JAR, JB2, JS, M4A, MOV, MP3, MP4, NTFS, PST, RPM, RTF, Random, SWF, TXT, Tbird, URL, WAV, WMA, XLSX, ZIP. Each file type sample can be downloaded from the website:

Also included is a _README directory that includes a list of every file downloaded and a copyright statement for the files that are covered under copyright. You can access that directory at:

This “FLETYPES1” corpus supplements the files in the GOVDOCS1 corpus.

Please let us know if you use these by including this citation in your paper:

Announcement: hashdb toolset

October 24th, 2013 No comments

The text file govdocs1-first512-first4096-docid.txt containing MD5 hashes of the first 512 bytes and first 4096 bytes of every file in the GOVDOCS1 corpus has been removed.  This file was provided to assist with research of block hashes.  We have since created the hashdb toolset which provides support for creating and working with hash block databases.  Please refer to for downloading the code, continuing progress on this topic, and links to relevant papers including:

Distinct Sector Hashes for Target File Detection

A related masters thesis on this topic was completed at Naval Postgraduate School in 2012 and can be downloaded for additional reading:
