How to open OLE2 Compound Document Storage database? I have file called Thumbs.db that I seem unable to open with anything. SQLite Database Browser can't do it, nor can LibreOffice Base. Opening up the file properties tells me it's an 'OLE2 Compound Document Storage' file. I'm running elementaryOS (an Ubuntu derivative) on a HP Folio 13.

It's a proprietary Microsoft format. According to this, there's a independent utility called ripOLE that may open them.
