DOC
From Forensics Wiki
The DOC file format (document file format) usually has the .doc extension. Mostly these documents belong to Microsoft Word software files. However, other text editing software can be used to display these files (including WordPad, WordPerfect, OpenOffice and others).
The DOC file format should not be confused with DOCX.

Encryption
Versions 97/2000 encrypt documents with a very weak algorithm. This password scheme can be broken easily by several different products and it is possible to decrypt the contents without discovering the password. This is done by testing all 1,099,511,627,776 possible keys. Ultimate Zip Cracker by VDGSoftware is one utility that can perform this decryption.
