Hold'em manager 2 for studying

I don't know of a way to make a folder, but you can certainly mark interesting hands with different tags during play for review later.

There are 2 ways to do this in-game that I know of:
1) Use HM2 hotkeys: http://hm2faq.holdemmanager.com/questions/2941/HUD+Settings+%7B47%7D+Hotkeys
2) Right-click the hand in the table HUD (once the hand is completed) and select the appropriate tag - this is the method I use.

Are there any videos about using HEM to improve your game in detail , versus just tracking results? If there aren't would be great if an experienced winning user could make some.

Thanks for the answers!

Idk, there should be some videos about using HM2 for analyzing and reviewing. For me its the important part of poker to evaluate my plays. And its frustrating to go trough about 10k hands every week.. o.O

In W34z3l's Red Line Rampage series he shows how to do a lot of interesting filterings that really can nail down your weak spots. Sadly it takes gold status to view them.

If you can afford Leakbuster is a nice complement to HM2 that can be a good help not only to find leaks but also to deepen your understanding of all these stats.
