I just don't trust it for this task at this time. I can work around by creating a new parent directory and then copy-pasting the file tree between Explorer windows. (Granted, that interface has never made sense to me.) Something is badly wrong that I also can't get around by forcing it to re-apply the permissions. In some fashion corruption has creeped into the meta data and I start getting "Access denied." errors as Windows Explorer pushes a simple additive change in permissions down file tree. That is until I start to work with permissions on parts of the extracted tree under Windows and editing permissions or pushing down AD groups. Not quite what scenario is the root cause or what really is going on, but the basic story is that I can create the archive, copy it and expand it without errors or noticable trouble the website. The one issue I have had with 7zip / Windows Zip is around the task of moving the file tree of a website between CentOS 7 and Windows Server 2016 (2008 R2, 2012 R2 also) or the other way around. I use 7zip across my servers because I can install it wherever I need it and it does much better compression than Windows Zip. To sum it up, a software like 7-Zip or WinRar is focused on providing users the best tool to manage archives, while the integrated Compressed Folders utility in Windows is just a component of an extremely broader scope software, and consequently is focused in staying simple, issue free, and easy to maintain as possible in order to cost the minimum possible manpower to Windows shell/GUI development team.I use Windows built in zip when I send something to others - clients especially, or colleagues. data transfert errors, bad disk sectors).īoth formats offers good encryption, optionally allowing to hide name of files inside archives.ģ - Alongside format-specific advantages, a dedicated utility often offers easy access to advanced options which makes the life easier to users, such as spanning the archive in multiple volumes (so you can stay under a certain size), compress files separately, delete after compression or after extraction, convert existing archives to other formats, etc RAR offers recovery record allowing to repair archives getting damaged to some extent (i.e. Or you may want to disassemble a container file (installer, Office file, JAR, etc).Ī dedicated utility simply supports far more formats, and some times this alone makes the difference.Ģ - 7Z and RAR offers many advantages compared to ZIP standard.īoth formats provides compression algorithms that compresses better than classic ZIP's Deflate, and which scale well on modern multi core architectures.īoth supports solid compression, that works very well if you have multiple copies of the same (or similar in content) file, which occurs quite often on large backup tasks. Or you can find valuable content in obsolete archive formats. And working with people using Linux or Mac you can easily need to open TAR, GZ, BZ2, XZ files. Of course ZIP is extremely popular, but you can quite commonly run into 7Z, RAR, ZIPX archives. There are various reasons to use a dedicated archive manager utility, the relevance of each is of course relative to the user's needs.ġ - Support for more archive formats.
