| According to what I have read from other postings to
this newsgroup and on the Internet, StuffIt is a
very controversial archiver and except postings which
look to me like advertizing (in my eyes it is just not
possible to recover large area of damaged data at
the cost of 1-3% larger archive) I have not heard
much good about it.
By the way: I have already got WinRAR and
in its headlines it promises same features, but
going into details of its helpfile shows, that:
"1% of the total archive size, usually allows the
recovery of up to 0.6% of the total archive size of
continuously damaged data" and
"it is impossible to recover files, which fail the
CRC validation" (in case the process of
repairing using the recovery record failed)
even if "it is still possible to recover
undamaged files, which were inaccessible due
to the corrupt archive structure." (but not in
case of solid archives)
Beside this, Stuffit is like WinRAR not free and
there is no source code available allowing to
investigate if it actually does what it promises to
do. In addition I can't evaluate Stuffit without
exposing any credit card information, so:
Any other hints?
