How to get each frame saved each in one file?

[pengo]

Hi to all
I'm new here and with Corona I'm testing an interior I did eith Vray. I got a huge impression by this rendering engine.
The only thing I'd like to understand is how to get each frame saved one file for each rendered image calculated.
I try to explain better. I gave a sequence of frame to render, every camera position has its frame. I gave the list as i always do in vray. first to send the calculation I put 0 to during rendering autosave they keep too much space on HDD and leaved final render 1 file.
Could someone help me to understand why i get only one file with all the renders that seems overlapped?
Thanks in advance and sorry for my english

I didn't understand all you wrote but to render a sequence as separate files for each frame (a sequence of .jpgs .tifs or whatever you want):

1. set time or pass limit in "progressive rendering" tab
2. in max's "common" tab set "time segment" or "range" or whatever just to render a series of frames
3. chose output file name and folder
4. render

Don't use autosave. It is used to "backup" rendered image and it will always save in .exr.

Thanks Maru
Of course I used in max common tab exactly in frames field the sequence of frames as I usually do in vray, but the lastrender.exr  autosave option gaves saved in corona folder (in folder //user/appdata....) a unique file with all frames renders overlapped in it (more merged I'd say).
That's strange I supposed that automaticallu i would get a progression of files saved. One for each frame.
I remember I did what u indicated as point 3 and I got black image renders.So i tryed the output autosave opion putting 0 files to the during render option and 1 for the n render end opion. I'll retry the standard workflow
Thanks
