Not an expert in terminal but ran this.
cd /sailfish
/sailfish/ # ls -l
Total 0

Is that ok?

Makes me think I have no files.
I have to add that I saw all the files being listed on the terminal screen while they were extracting. Took about 30 minutes or so.

Sorry its a bit long but these are the folders in the oss file-
