^ Did you even read what he posted?

As for the opening post, you can achieve this via the command line switch -vn

By default RAR volumes have names like 'volname.partNNN.rar', where NNN is the volume number. Using -vn switch it is possible to switch to another, extension based naming scheme, where the first volume file in a multi-volume set has the extension .rar, following volumes are numbered from .r00 to .r99. It may have sense, if you are going to unpack an archive under the plain MS DOS, which does not allow more than one dot in a file name.

E.g. winrar.exe a -vn "output.rar" "file.ext"

I usually use this when storing a large file:

winrar a -v15000 -m0 -vn -rr -ep <dest> <file>

You can see all the command switches in the WinRAR help file.

You don't need to use it, but they help if an archive gets damaged. You can also read more information about them in the help file...

Copy/Paste information from Help Topics | Index | Recovery Volumes:

Recovery volumes


--------------------------------------------------------------------------------


Recovery volumes or .rev files are special files which can be created by WinRAR and allow to reconstruct missing and damaged files in a volume set. They can be used only with multivolume archives.

This feature may be useful for backups or, for example, when you posted a multivolume archive to a newsgroup and a part of subscribers did not receive some of the files. Reposting recovery volumes instead of usual volumes may reduce the total number of files to repost.

Each recovery volume is able to reconstruct one missing RAR volume. For example, if you have 30 volumes and 3 recovery volumes, you are able to reconstruct any 3 missing volumes. If the number of .rev files is less than the number of missing volumes, reconstructing is impossible. The total number of usual and recovery volumes must not exceed 255 and the number of recovery volumes must be less than the number of RAR volumes.

Original RAR volumes must not be modified after creating recovery volumes. Recovery algorithm uses data stored both in REV files and in RAR volumes to rebuild missing RAR volumes. So if you modify RAR volumes, for example, lock them, after creating REV files, recovery process will fail.

WinRAR reconstructs missing and damaged volumes either when clicking on .rev file, or when using rc command or automatically, if it cannot locate the next volume and finds the required number of .rev files when unpacking.

You may use "Recovery volumes" option of Archive name and parameters dialog or the similar option in Protect archive command to create recovery volumes. In the command line mode you may do it with -rv switch or rv command.

Original copies of damaged volumes are renamed to *.bad before reconstruction. For example, volname.part03.rar will be renamed to volname.part03.rar.bad.

It's similar to parity volumes. There are few apps out there for PAR and PAR v2 file formats. That works nice when you are using an app that splits files for you but doesn't directly support recovery volumes. The downside to them is that you need an app to recover using PAR files...but then again, all the good ones are usually free anyway so...and you still need WinRAR itself to recover using their recovery volumes so it's a horse apiece.

Even a google search for "how to use par files" will give you some nice hits on the explanation. You probably don't need it, but the top 5 hits are normally great resources for a better explanation. And they *really* come in handy when you are dealing with larger archives or a large amount of splits for your package.

    • You are mostly right about the ephemeral nature of it. As I mention in the article, if you dont add a second device or take a backup of your account before uninstalling it, then yes you will lose access to your account. That said, in terms of actual user experience when you sync multiple devices your message history carries across and there's also a Saved Messages chat like there is on Telegram to send messages and attachments between your installs. But yh, what you point out are correct and its not trying to emulate Messenger or Telegram.
    • OK so SearXNG is a meta search engine that you can install locally or use via a public instance. It scrapes other search engines which you choose and then sorts the results. Not as complicated as multiple relays
    • The only difference here is that you think you came up with these reasons. You didn't. These age old fearmongering lies (that were NEVER true) were funded by and the anger stoked by Putin through proxies like Farage (and later in the USA, Trump) and filtered down through the skinheads, Neonazis, etc. until it reached the uninformed, ignorant, and gullible -- never realizing they were being played for fools against their own best interests. Even now, despite all of the EVIDENCE proving that Brexit was a terrible mistake for ALL citizens of the UK and that its supporters were tricked by Putin's proxies into sabotaging their own nation, you're still here defending these well-known lies as if they were ever true. Not only are they not true. They NEVER were. So, when are you going to realize that you were lied to and actually get angry at the liars and charlatans who lied to you, instead of blaming the innocent people they lied to you about?
