UNIX for Beginners Questions & Answers

Good afternoon, I started apologizing for not creating a specific topic with my subject, I could not find the option to create a topic, friends, if someone can help me thank you very much, I have a problem, I have a DVR with a HISILICON HI chip 3520, it compresses and encrypts the videos recorded by the security camera, compressed it with some unix extensions like ".Z" also compressed with .zz .hyp and .vp6 I know .Z is a file extension for unix files, but I never used it unix or linux, I believe the OS of my DVR is based on UNIX, how can I unzip these files? I removed the HD from the DVR because I lost the password and I could not even with the master passwords reset the DVR, then I placed the HD in the computer and I used data recovery software to try to recover the videos, but they came with these formats ... somebody can you help me? Sorry for my english, I live in Brazil and I'm using a translator

Hi Christopher,

Welcome to the forum, please take the time to read the rules and learn how to post. To start a new thread, open the appropriate forum and at the bottom left there is a new thread Icon like two speech bubbles.

As to the unix utility to deal with a compressed file with a ".Z" extension it is uncompress filename that you would use. I think that WinZip might deal with the format as well, supposing that you want to use Windows.
