I have got to question.
1. Do I need to do .RESETSESSION before I creation of sav file? I had read docs, but do not understand when I need to do it.
Could you explain the situation when I need it.
2. How I can get in variable path to ENVI Extension folder? I know that it's can be setted ai ENVI Settings, but how I can get path to it with IDL?

I am not sure I completely understand your questions -
- typically, when creating a .sav file that is a user function for ENVI, we suggest you start a 'fresh' IDL session and then perform the steps described in the ENVI Classic help under Sample Code and Instructions > Working with User Functions > Adapting User Functions for ENVI Classic > Creating a Save File.
I am not clear on what you want to do with the path to the ENVI extensions folder. You can add in paths from IDL from the IDL preferences under Preferences->IDL->Paths.

What will happen if I will not do reset session before creation sav file?
Ok. I know about preferences, but how I can get this path from IDL code?
Example: I need to cal from one sav file another sav file with absolute path? And this path is path to extension folder.
something like:
$dir = %extensionfolder% + 'foo.sav'

The ENVI Help discusses best practices and RESET_SESSION under Programming > Toolbox Extensions.
I don't think there is a specific variable holding the ENVI extensions folder. The path is listed with the IDL !PATH variable.
