PokerTracker

As of the topic, am thinking of purchasing poker tracker as I've been using the trial version for about a week now, what are the difference between the mentioned two? Are they the same but only the small stakes version only allow tracking on small stakes table? If so, what is the highest stake it can go for the small stakes version?

There is no difference between a small stakes version and a full stakes version apart from the stakes that are supported. A small stakes license is limited up to and including the following limits:

No-Limit & Pot-Limit: 0.25 / 0.50
Limit: 0.50 / 1.00
Tournaments & SNG's: 22.00 buyin

Thanks! You've cleared my doubts. I have another question though - where are the database files located? I'm using the trial version of it now and I can't seem to find it on my mac.

The database files are managed by PostgreSQL and can't be altered externally without corrupting the database. There isn't a single file which holds your database - it is spread across multiple files in the Data folder within the PostgreSQL installation.
