First, the hts-cache folder may be responsible for a 
part of the problem - you can safely delete all old.* 
entries in this hts-cache/ folder.
Then, if you want to keep the website but do not want 
to update it in the future, you can simply wipe out 
the hts-cache folder itself, as it is only used when 
updating or continuing an existing mirror.
This might be the solution!

A last note: nothing is compressed when mirroring with 
HTTrack - because the mirror has to be identical to 
the online version, and must be browseable with any 
browser - therefore all local html files stored are 
real html files, as all other files
