HI!
Thank you everybody.
Its little bit clearer.
Im just student. I have some result from MS Project and I want to know how it works in real word:)

Jaroslava,
Free float is the delay an activity can have without delaying a successor. Total float is the combined delay a chain of events can have without delaying the end date (end date being a specific fixed completion milestone).
Therefore, the result of activity Y being delayed by 7 days is that its Total float has been reduced by 7 days. You are right that 5 will not impact any successors but 2 will delay at least one successor X. Worth noting is that X does not necessary have the same total float as Y as X might be related to a second chain of event with a larger Total float.

float is refreshing during summer time...if you had established good relationships.
seriously, float only occurs because of dependencies, if there are no dependencies in your activities, each activity has its own completion date without any float at all.
It depends on how you define the relationships of your activities (pls. refer to the first paragraph). so if the relationships are incorrect, so is the float!
Hi, free float is the float between noncritical tasks. Total float is float between noncritical and critical task. Assume that we have 3 tasks A, B, and C. A and B are noncritical C is critical A is predecessor of B, B and C has finish to finish relation in this example A has total float but its free float is 0 but B has both free float and total float. we can understand here when A finishes B starts immediately if a delay occurs in activity A, this activity will use Bs float becouse As free float is 0 in other words it hasnt got its own float. I hope it would be useful for you.
I would personally take the Free Float off of the columns, assuming you are using P3...
Total Float is the only thing worth looking at in my opinion...I have never used Free Float or seen it in any schedules I have ever worked...
