Software for managing Word files (doc, docx) archive I have an archive of .doc/.docx files, which I'm frequently using to pull some information. I'm looking for some software that would allow me to search through the content of all these files (Mac OS X 10.7.5).

Note: I haven't tested Spotlight because I've turned it off some time ago (because of power consumption related to file indexing; I also didn't need it before).
I'd suggest you look at the File Content Finder (disclaimer - I'm its developer). It's specifically designed for searching file contents without indexing. It supports all major file formats - pdf, doc(x), xls(x), pptx, rtf, and others. It can also search in scanned png and jpg documents.

Its filtering lets you optimise and refine your search by multiple criteria - file type, creation/modification dates, etc.

Cost: $9.99 USD.
