Hello! 
I do know that this topic has been covered, but have not been able to find
answers regarding my specifik questions.  

This is my use-case: 

- I will use Httrack to archive several different websites. 
- I will download the websites on 3-4 occasions this year. 
- I want different packages each time so I will not be updating the earlier
package.

My questions regarding the contents of the hts-cache folder:

* I have an inkling that perhaps the new.txt file and the winprofile-config
file in the folder could be of archival interest. It seems to contain
information of what has been downloaded and the settings I used. Or is this
information in any other log in the package?
* I am wondering about the "new.lst", what kind of file is this and can it be
removed? 

* It is my understandning that the "new" zip-file is only of use if I want to
update the mirror. In my case, where I will not update the package, I could
safely remove it, is this correct?
Many thanks!
