1. how to associate my files with my apps.(like pdf with evince;txt with leafpad .etc)

You can do this with gnome in corepure64 by double-clicking on a file in nautilus - it will ask which app to use to open the file and remember from then on. I haven't tried with nautilus outside of gnome. I also seem to remember that there was a way to do this with emelfm.

2.which screeshot solution or software is commonly easy to use?

There's a screenshot utility built in - click on the desktop, then choose SystemTools/ScreenShot

3.how to increase the system volume when i watch web video?

Do you mean add a swapfile or increase hd partition space?

can u recommend some or help me? i don't know how to search the keywords about these.

Use the Apps gui, select tags and enter "screenshot" for example

  Juanito,thanks for  ur nice advice,
1.i do not want to install gnome,(it seems so big and too many deps) ,do i have another solve to the first question?
2.i will try it later.
3.i mean the ''sound volume"
Thank you again

You don't mention what you're using for sound, but assuming you're using alsa, open a terminal window, enter "alsamixer" and use the arrow keys to adjust the volume.
