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:

test disk image of emails available

February 2nd, 2011 2 comments

I have created a new disk image called 2010-nps-emails that can be used for testing programs that find email addresses or perform string search.

The disk image consists of 30 different email addresses, each one stored in a different document with a different coding scheme.

Below are a list of the email addresses and their codings:

email address                             Application (Encoding)                   Apple TextEdit  (UTF-8)               Apple TextEdit print-to-PDF (/FlateDecode)                     Apple TextEdit (RTF)                 Apple TextEdit print-to-PDF (/FlateDecode)                  Apple TextEdit (UTF-16)              Apple TextEdit print-to-PDF (/FlateDecode)                         Apple Pages '09                 Apple Pages (comment) '09                       Apple Keynote '09               Apple Keynote '09 (comment)                       Apple Numbers '09               Apple Numbers '09 (comment)                Microsoft Word 2008 (Mac) (.doc file)            Microsoft Word 2008 (Mac) print-to-PDF           Microsoft Word 2008 (Mac) print-to-PDF (.docx file)           Microsoft Word 2008 (Mac)             Microsoft Word 2008 (Mac)          Microsoft Word 2008 (Mac) (Comment)               Microsoft Word 2007 (OLE .doc file within .doc)             Microsoft Word 2007 (OLE .doc file within .doc)               Microsoft PowerPoint and Word 2007 (OLE .ppt file within .doc)             Microsoft PowerPoint and Word 2007 (OLE .pptx file within .docx)               Microsoft Excel and Word 2007 (OLE .xls file within .doc)             Microsoft Excel and Word 2007 (OLE .xlsx file within .docx)                 text file within ZIP             ZIP'ed text file, ZIP'ed                text file within GZIP           GZIP'ed text file, GZIP'ed

Edit, 2011-11-26 19:32 PST: One email was incorrectly recorded above. is within the disk image, but was recorded here. That is now corrected above.

Bots downloading disk images

December 27th, 2010 1 comment

I’m preparing some statistics on who (and what) are downloading the disk images we have here at The first thing that I’ve done is suppress the bots that are, for whatever reason, downloading the images.

Here’s the bots that we’ve found, and the number of times each image has been downloaded by a bot.
