I have a similar query, but regarding cases where there are a large number of documents / spreadsheets.
In some cases, we have a lot of docs & emails which need to be presented to users without much technical knowledge. It would be useful to have a (hopefully cheap) tool which would be able to index these documents, present them in a sensible manner, and allow certain searches to be performed.
Currently we either a) batch export them all and put up with a basic Windows search, or b) present them via EnCase. Neither is an especially satisfactory solution.
I know dtsearch does this, to some extent, but from our tests it looks like it misses some information - for example, as it turns everything into HTML, it seems to miss some embedded images in documents. We've also tested Archivarious 3000, which seems good (and is super cheap), but is not a forensic tool so we're a bit wary
Any pointers would be useful - especially if the software has a demo!
