If the data is compressed, it will probably not be understood by
anything other than gunzip, and even not that if there is not a proper
header.  You probably will not see anything familiar in the file (nor
will any other reader/viewer) without somehow decompressing it.

Perhaps you could find out what a gzip header looks like and search
for it at the beginning of the recovered files or on the NTFS
filesystem.  Note that I can not provide more than a little help from
here on, I am familiar with no more than (or less than) the basics of
data recovery.
