^ 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've tried DuckDuckGo and Brave Search, now get serious with SearXNG

      By zikalify · Posted

      You've tried DuckDuckGo and Brave Search, now get serious with SearXNG by Paul Hill Over the last decade, it has become quite trendy to dump Google Search in favor of privacy-preserving alternatives such as DuckDuckGo, Startpage, and Brave Search. These search engines have done a very good job at highlighting dodgy practices by Google, such as adjusting search results based on what it thinks you’ll like (filter bubble) and stalking you around the web to advertise to you. While these search engines are good starting points when compared to non-private services like Google, there are still quite a few issues with them. For example, both DuckDuckGo and Brave Search require running non-free JavaScript in your web browser, which is comparable to running proprietary software on your computer, meaning you can be sure about what it’s actually doing in the background. Another issue is that these search engines are hosted on the respective companies’ servers, and you are using a service that you don’t control. Finally, DuckDuckGo, while offering privacy features, relies heavily on Microsoft’s infrastructure for its results and, in the past, has permitted Microsoft tracking scripts. If you are looking for a more private search solution than DuckDuckGo, Brave Search, and Startpage, then I recommend taking a look at SearXNG. It is a privacy-respecting metasearch engine that can be used via different public instances, which is useful for mobile users, or you can install it on your computer or server and run it locally with maximum control. Unlike Google, Bing, or Brave Search, which crawl the web and have their own search indexes, SearXNG is a metasearch engine, meaning it taps other search engines, stripping your identifying data, such as IP address, user agent, and cookies, in the process. Your search query is sent to the other search engines you enable before aggregating the results. SearXNG has deployment flexibility. If you are a casual user or a mobile user and don’t want to run SearXNG locally, you can use a public instance that is hosted by someone else. The main problem with this is that you are putting trust in the maintainer of the instance regarding stuff like logs that they may keep; good hosts should have a privacy policy explaining their policies. If you are trying to use SearXNG, you can also install the software on your device and then head to 127.0.0.1:8080 in your browser and search from there. While you don’t have to worry about a third-party admin like the public instances, search engines could ultimately block your IP address if they frown on you pulling in their search results locally. If you want to run it locally, it’s a good idea to use proxies or VPNs to hide your actual IP. You don’t have to worry about this with a public instance, as search engines never see your IP address. The main privacy benefit of using SearXNG is that it isolates your identity from the underlying engines that it’s capable of searching, such as Google and Bing. These search engines will only see requests coming from a generic server, so they can’t profile you and create a bubble filter that influences what results you see. This also ensures that your search engine doesn’t turn into an echo chamber that prevents you from reading alternative points of view. As a free software project, you are allowed to inspect SearXNG to make sure there are no negative features bundled inside. This sets it apart from the privacy search engines mentioned earlier because you can’t check their source code. As a meta search engine, you are not restricted to getting results from one source. Due to the fact that it scrapes content from other websites, your SearXNG instance will periodically get blocked from different providers, so it’s good to select a range of sources as a backup. While enabling all of the services will give you great results, this can make searching slower. I am personally happy with slower searches for the best results, but you can always check which providers are slowing down your search from the search results page and disable them to speed things up. If you want decent results quickly, enable the main search providers such as Google, Brave, DuckDuckGo, Qwant, Bing, and Yahoo. This way, you get wide coverage without the latency. On the Engines tab in Preferences, do note that there are different tabs, such as General, Images, and Videos, with their own providers that can be toggled and are not covered by "Enable all" while on the General tab, so be sure to dig into each. Just a note, if you want to enable everything, press "Enable all" in one tab, then hit save at the bottom of the page, then do the next tab, and so on. If you press "Enable all", then do that in each tab, and then save, nothing will stick. When I had just some of the search engines enabled, I searched “define nefarious” and results came back with the definition of “define” - obviously that was a sucky result. However, when I had everything enabled, it found dictionary pages for the word “nefarious” and even had an inline definition on the sidebar, which is quite nice too - that was delivered by WolframAlpha for anyone wondering! Probably the worst thing about this meta search engine is that the engines you select are saved with a cookie, so you must enable them on every new device you use SearXNG on, including if you decide to go into incognito mode with your web browser. Honestly, I would say this is the most annoying aspect, and perhaps if your browser lets you choose a separate private browsing search engine, then it would be best to use DuckDuckGo for this portion of your browsing. Another weakness of SearXNG is the random blocking of it by search providers. When you are on the results page, expand the “Response time” box, and it will show things like “Suspended: too many requests” or “access denied”. This is why it is good to enable several providers so that there is always a fallback to get results from. I won’t pretend SearXNG will be for everyone, however, if you enable all of the providers and put up with the slower response time, the results can be really amazing. Even if you don’t want to use it as your daily driver, keeping a bookmark handy that links to it is a good idea if you ever feel like doing a deep dive into a niche topic where other search engines are just failing to bring up any good result, due to the amount of sources it looks on. If you’re interested in radical user control over the software you use, installing SearXNG locally can also be a good idea, but be prepared to be temporarily blocked from sites if you trigger bot sensors without a VPN. Personally, I’ve opted to use a public instance, rather than install it myself. If you want to use it via a public instance, head over to searx.space to find a provider. Let us know in the comments if you have used SearXNG or its predecessor, Searx. What do you think about the quality of the results?

      Dear Neowin, If it is not too much trouble, can you start using the new-ish designations for Insider Preview? "Experimental" is different than "former Dev" as it can apply to different models, eg 26H1 or 26H2 etc, right? No need to seed confusion IMHO. And, please "finally" update your graphics. OK?

      Just install Linux Mint that is a real blessing and many times cheaper because you can continue using your old Windows computer/laptop with the latest Linux updates.
    • Why Delta Chat is the best decentralized messenger you have probably never tried

      By Nas · Posted

      Interesting share -- however it does not make sense: Email messages get stored somewhere, so how is Delta Chat "based on email" and decentralized without actually storing anything? By Web3 standard practices, the various Relays would require dedicated storage to make messages available to the recipients (like a large series of message queue channels, akin to racks of traditional post office boxes)... and Contacts must be two-way confirmed in order for encryption keys to be exchanged (ostensibly every key-pair is uniquely bound between sender and recipient) and the Relays would preserve the public keys in order to facilitate message carriage... or every device stores all sorts of keys and contact info. All of this to say, decentralized messaging is like running Bluesky nodes except instead of discovering/browsing public feeds by various posters (at the given node) these Delta Chats would be relaying encrypted messages (via Relays) that only trusted recipients would have the appropriate decryption key (their own private key) to read it. But this doesn't solve the "it's like email" sales pitch. The only way it's like email is that there's encrypted binary stuff being transported from your app into the federated ether of Delta Chat Relays for others to decrypt (hopefully only the intended recipient)... but outside of this federated relays framework, it is absolutely nothing like email.
