Hello Rolly,

Hover the mouse pointer over "Database Information" in the AB status 
bar - a tool tip gives the database path, number of symbols and the 
number of quotes in the current symbol.

I have posted a few tips and tricks on this topic at:

http://www.amibroker.org/userkb/category/data/yahoo/database-management/

There's more to come in the future and if you can give me some more 
specifics on what you mean by "to check if the db contains up-to-date 
symbols against a market." I will include an answer in a future post, 
if I can, although I suspect I have already answered that question for 
Yahoo EOD users.

That would be nice for all folders in the Symbols Tree but then I am a 
self confessed GUI guy.

I think some of the power users are against bolting stuff on and anywat 
Tomasz is a speed freak from way back so he is against hanging too mcuh 
stuff off AB.
