Thumbs.db is a system file that contains the thumbnail cache–a collection of thumbnail images for photos, documents, Web pages, and so on–for a particular folder.

I am trying to build DB_File perl module on a AIX box. I have built and install BerkeleyDB 4.8, it is installed at /usr/local/BerkeleyDB. When I attempt to build the module, this is what I receive ...

And, due to stupidity, I deleted the DB file (s) hoping that you could force File History to "reattach" to that store, scan it, rebuild the DB and we could get on with life.

In conclusion, while the discovery of the consolidated.db file’s behavior is concerning, it is reassuring to know that it is likely a bug rather than a deliberate design choice.

For starters, the consolidated.db file stored location data for up to a year. Users naturally wondered how old data was useful in Apple’s efforts to determine location today.
