You need software that allows you to configure compression. By right-clicking on an item, you should find a command like Add to archive. By selecting it, a window should open, allowing you to make adjustments. The compression rate is determined by the option chosen in a menu called Compression method or something similar (you can also access these settings by running your compression software through a shortcut. You then need to select the item to compress in the window and click on "Add" in the toolbar).

The dropdown menu allows you to choose from several methods, ranging from the fastest to the slowest. The best compression rate is achieved by the slowest method.

That said, compression is not only used to reduce the size of items. It also allows you to group several items so that they constitute a single file. This enables you, for example, to send folders over the internet or to burn to disk items with names not recognized by the burning software. Therefore, it is not always necessary to have a high compression rate.

I tried a lot of software; among them WinRAR, which compresses Word files well; but aside from that, I set the parameters but it doesn't change anything
I also used 7-Zip, KGB Archiver, WinAce, WinHua, and a few others; but I can't get a good compression rate (barely a few KB less).

Hello!
You should know that the greater the file compression (compression rate), the more the PC will lag when compressing and decompressing files. This is especially true if you are working with large ones!!

I’m also looking for a software capable of reducing the size of a file (.exe). I tried WinRAR but got very little result as well. If you managed to find a good software that reduces it by at least half, I'm interested...

I would also like to achieve a high compression rate to reduce a 78 MB PPS file to 10 MB to send it by email, or if you have another solution, I'm open to it! Thank you

Is it possible to send a VIDEO (compressed ZIP format) of 790 MB as an attachment?

It is possible to send very large files by email using BitTorrent clients like:

Podmailling
Free and in French.

Portable version available at this address:

Pando
Offers a free version, with a French pack (to be added) but it only works if the recipient has also installed Pando.

Hello everyone  How is it that when I compress a file, the compressed archive is larger than the file itself when it's not compressed???  Thank you

I'm bringing up an old topic, but I advise that if you have large files to share, it's better to use a sharing site rather than a compression method, which will be much more complicated and slower.

For example, Dropbox is very good; you just need to move the concerned file into a special folder on your computer or online, and it will be uploaded online. You can then share a link that will give access to this file to anyone who has that link. With the ability to delete the file or change the link if people you don't want have acquired that link in any way.

As for sending large files via email (which can reach a gigabit), I recommend "WeTransfer"; it works very well, I use it often for my work.
