That can compress in "rar". And you can choose to take the external compression programs, so that in the future, always continue with the maximum compression security of that moment.

That can compress in "rar". Here I explain why, and some ideas so that your program can last decades, as the best.
I know that the .rar data compression system is paid. I know. We know.
But for a long time, many years it has worked.
It has been used extensively, and continues to be used.
There are things in which 7zip is better and there are things in which rar is better.

But leaving it aside, I think it is not correct.
It has been very useful to everyone in the world and to all computer scientists for many years.

And I think that we must give the opportunity to companies, and to those responsible for information technology in companies, to also be able to choose rar.

Because they trust him.
Because it has a file repair system, etc.

It is true, that after many tests, 7zip beats rar in many things.

But rar, it's still going strong. And works. And it's safe.

So if I may:
I strongly urge you to also allow your great and fabulous program to be able to compress into rar.
You know, it's just add in the dropdown, zip, 7zip, rar.
Surely later on there will be computer scientists who will also ask for tar, bzip, etc.

But the rar is very important.
It would be something like going to the restaurant and only eating the first course.

And once the Administrator has chosen rar, the internal compression switches are very similar. It's just doing the conversion of switches/flags.

That the program can be chosen in the folder where it is installed.

-----
Also another topic:
In the supposed event that something happens to you, so that the program can continue to function for decades and decades,
It would be necessary to add in the configuration of each one of the compressors, two text entry fields in each type of compressor:

* Choose the external program to compress in "rar".
* Switches that will be used to compress in "rar"

* Choose the external program to compress in "7z"
* Switches to be used to compress in "7z"

* Choose the external program to compress in "zip"
* Switches to be used for compress in "zip"


If the place where the compressor program is installed were configured, it would use this one, instead of the internal one. And the switches that were configured there would be used "exclusively".

This is also ideal, for example:
* If new switches come out
* If the compressor program in the future offers more security than the internal compressor.
(You have to keep in mind that the security of 7zip and rar, are releasing new versions and patches every day, to offer more security, and more and better encryption).
Let's say, for whatever reason, you could no longer (for whatever reason) continue with this program, as has happened in the past.
In this way, it is ensured that this tool is eternal, and super functional, and safe, and with future encryption that is later. Even if you couldn't continue with this project.
Therefore, being able to access updated and up-to-date external compression programs ensures that your program lives on in the future.
And go down to posterity as the best backup program.
More things can be done. But you can start there.

Thank you very much.

I will be very glad if you or anybody can buy me a rar license with distribution rights. I will be glad to implement this then.

[streik]

Total Commader (from https://www.ghisler.com/) and the freeware program PEAZIP (https://peazip.github.io/)allows you to choose the Path and the program you want to use to decompress and compress rar in the compressors section.

You do not need a distribution license if you do not include this "external" software in your package. It is external. External. This software is separate. It is not included in the cobian download.

Let each user buy their own winrar program. If you want to use it, of course.

It is the one who uses it who has to buy the license, because you "do not include it in your package". Therefore, you do not distribute it. Therefore, you do not need a distribution license.

Your program only (and that's a lot) helps the following:

* Helps to program "WHEN", "WHAT DAY AND TIME", the backup has to be done. (if on Mondays, Tuesdays, etc).

* Helps to make backup types: Full, incremental, differential.

* Helps in windows to set the File "A" bit to know if in the next backup it is necessary to make the backup, of:
- New files, and
- the modified ones,
- or copied into that source folder,
if you have to make the backup.

That is, say schedule "organize" and "schedule the days" of the backups.

But the one who actually installs the winrar program is not you.

In fact, you don't need to use the word rar anywhere.

You can simply put that if the Administrator wants to use a different compressor, you can configure the path with the .exe file that the administrator wants.

And below, that he can add the switches/flags that he wants to add.

To go well, there should be at least the possibility of configuring three to five external compressors in this way.

External programs that each Administrator can configure the client the path + .exe, and the switches/flags:
zip
rar
7zip
tar
bzip
peazip

On this Peazip website, I did so verbatim, and for many years it has allowed the winrar program to be configured, but it already clarifies that the user has to install it, and that if he wants to use it he has a few days of trial, and if he wants to continue using it, then you have to buy it.

The PEAZIP website says this:

https://peazip.github.io/free-rar-create.html

"PeaZip, freeware and open source archiver utility, can open and extract RAR files on Linux and Windows, using the Open Source code written by Igor Pavlov in 7-Zipfree rar file archiver and its POSIX port p7zip project.
Additionally, PeaZip can automatically configure itself to use WinRAR's Rar.exe to create RAR files from PeaZip's own GUI, """"but only if WinRAR is installed in the system"""""."

In other words, you never distribute it, because you don't include it in your package.

You only ask the end user, if he wants to use external compressors, the user can put the "path" where the .exe "that the user has installed" is located.

In Linux and macOS for example, as in Windows, there is the program "Krusader" from (krusader.org), and others, such as "Total Commader", which are file managers and explorers, similar to the old predecessor " Norton Commander", allow you to configure the "path" where the user has installed the "rar" compressor.

That is why they are utilities so valued by programmers and users, because they facilitate "only in GUI mode", to use, schedule the days of the backup, full, incremental, differential, say the "A" file bit, they facilitate in GUI mode , using the rar compression tool, "but what, always and at all times", the one who has to install it with a 30-day trial and buy (if you want to continue using it), is always and in any case the end user .

Also put, in your backup tool, "Cobian Reflector", "as many others have had for many years", the possibility of being allowed to "choose" external compressors, and another text field, so that the user can put the switches/flags to use.

Thank you very much

Yes but you won't get any feedback (like the percent of done operation) or you won't have the possibility of canceling or pausing.

No.

[streik]

It doesn't matter, Luis.

The important thing is that the Administrator and the world choose, if you want to use it.

And in addition to external rar (and that the user can put their own switch/flags), also, that can be configured, various types of external compressors, although they cannot receive comments, or the percentage, or pause, or cancel, these are:

zip (external path) (With a text field to configure the desired switch/flags)
rar (external path) idem
7z (external path) idem
tar (external path) idem
bzip2 (external path) idem
gzip (external path) idem
peazip (external path) idem

In other words, if a thousand years pass, and we no longer exist, you can continue using your tool, with the latest improvements, in the latest compression version, with the latest encryption security.

That the user can choose, if he wants to use an internal compressor, or an external compressor.

Thank you very much

Out of curiosity, what does a RAR license cost? If you know.

I don't believe that's the license he needs.
