Recovering password protected .zip and .rar files are easy, possibly because these formats are widely used and covered. However the same is not true when it comes to 7z zip files.

7z Cracker is a simple command line software that has the ability to recover lost password, it uses brute force, which is in layman’s words – guessing. By guessing 6 possible combinations per second, 7z Cracker might be able to recover the lost password within hours, depending on the complexity of the password.
7-Zip, it is an open source software. It is known for its high compression ratio in the new 7z format with LZMA compression and it is free. It may not be the best zip compression software but it is free as opposed to others with a high price tag.
Which is the best Zip Compression Software?
Below is a simple test I performed, and it clearly shows 7zip is one of the best.
WinZip | WinRAR | 7-Zip | Microsoft Zip | |
|---|---|---|---|---|
| .zip | .rar | .7z | .zip | |
| Documents 5.92MB • 1 Microsoft Doc • 1 PDF • 1 TXT | 4.79 MB | 3.38 MB | 3.22 MB | 4.79 MB |
| Applications 76.6MB • 7 Exe Files | 73.8 MB | 72.5 MB | 72.8 MB | 73.8 MB |
| Images 42.3MB • 16 Jpeg | 33.2 MB | 33.1 MB | 20.2 MB | 33.3 MB |
| Movies 66.1MB • 4 FLV • 3 AVI | 58.9 MB | 55.1 MB | 54.0 MB | 59.0 MB |
| Photoshop 3.64MB • 3 PSD | 2.19 MB | 1.56 MB | 1.37 MB | 2.19 MB |
| Total Original Size: 194.56 MB | 172.88 MB (11.14% smaller) | 165.64 MB (14.86% smaller) | 151.59 MB (22.08% smaller) | 173.08 MB (11.04% smaller) |
Here is another comparison carried out by 7zip themselves. The compression ratio results are very dependent upon the data used for the tests. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. And 7-Zip compressed to zip format 2-10% better than most of other zip compatible programs.
i have an important 7z archive that i have forgot its password how should i use this program to recover password even in hours(in windows seven or vista)!
please tell me what to do
thank you very much.
Downloaded it, didn’t work.
It only go trough numbers, 1 to infinity… Lame
BEWARE of programs that don’t work. More often than not the download was designed to do something very naughty with your computer.
