Generally speaking most modern compression algorithms give roughly the same compression, and with regard to the number of cores that you can use at once, it is up to you to decide how many you want to use. However, 7-zip is free and open source. The 7z format supports encryption with the AES algorithm with a 256-bit key. The key is generated from a user-supplied passphrase using an algorithm based on the SHA-256 hash function. The SHA-256 is executed 218 (262144) times,[4] which causes a significant delay on slow PCs before compression or extraction starts. This technique is called key stretching and is used to make a brute-force search for the passphrase more difficult. Current GPU-based, and custom hardware attacks limit the effectiveness of this particular method of key stretching,[5] so it is still important to choose a strong password. The 7z format provides the option to encrypt the filenames of a 7z archive.

It is almost now and then we encounter the .ZIP file while downloading the Designs from the Embroidery Designs website. So, what is this .ZIP file? It is not an Embroidery Designs Format. Isn't it?

What is ZIP File?
Zip is a file format used for data compression and archiving. A zip file contains one or more files that have been compressed, to reduce file size, or stored as is.

How Do I Create My Own Zip Files?

If you want to create your own Zip files, then check out this useful tutorial.

1. Select all the files to add to zip file.
2. Once you select the all file, right click on the files and options will open to zip or rar the files as shown below.

In above image:

Add to Archive: It will open a new window with the following options (i recommended to go for zip file rather that .rar file.The reason are given at the end of this article)


Add to....: This options will automatically create the zip file with the name of folder without accessing the additional options. So there is no need of selecting the options and then click ok to zip the file, it will automatically create the zip file with out any options to check.

Software to Unzip the files?

The most comprehensive unzipping software with the best compression technology is Winace, available from http://www.winace.com/.It handles virtually every single compression format and is extremely easy to use.
The second-best unzipping software (in my opinion) is Winrar, available from http://www.rarlab.com/. Many times, you will find .rar files that need unzipping and for these, you will need Winrar to unzip.7 Zip is another good software to unzipped the files. 7-Zip is open source software. Most of the source code is under the GNU LGPL license. The unRAR code is under a mixed license: GNU LGPL + unRAR restrictions. You can download the software from the official website of 7 zip http://www.7-zip.org/

How Do I Unzip Files?
First, you need to download and install either WinZip or WinRAR archive software. Once installed, the archive software should now be part of your Windows or Macintosh system.

You open you a Zip file by double-clicking it. Commonly, one of two prompts will then appear:
•   "Unzip or install from an existing Zip file" in the WinZip Wizard. This Wizard will then walk you through the steps to unzip-extract the files.
•   "Extract files to..." in the WinRAR Wizard. Just like WinZip software, you will be prompted for the next steps. Give it several moments to do its job, and your files are now decompressed as separate complete files. You now use those files like you would any other files. If you want, you may also delete the Zip original file to now save space.

Following tutorial will show you how to  extract or un zip the file using Winrar:
1. Install the zip file opener software, without zip opener software this will not work.
2. Once you installed the zip file opener, the zip file icon will automatically appear before the every zip file.Please note that different software have different icon. In the below image i m using winrar software to open zip file.
Double click on the first file to open the zip file in a new window. Once you double click on the zip file it will open in a new window as shown in below image.

What if i want to open the file permanetey rather than every time double click and open it in a new window. That is i want to convert the file from zip file to normal file. In that case follow the following three option as shown in below image.

Extract File: It will open a dialogue box with all additional advance options as shown in below image.


Extract here: It will extract the file at the present location with out any options to select before it.

Extract to.... : The best option to extract. It will extract the files in a new folder and extract all file in that folder.

Some Useful Tips or Comment

1) Zip file is usually used to compress the size of the Files.So you can use to compress the size to some extent
2) It is used when you want to send some loss files in a one lot.By using zip function you can attached a lots of file together
3) It is also  used for the security reason,Because once you zip the file, file get it protected from the external virus.
Note: But it would be risk too.Because if you are downloading a ZIP files with virus then it is difficult to protect the computer.This is because it is difficult to identity the virus in zip file
4) From my personal experience one must used the "zip"  extension rather than ".rar", this is because it is easy to extract zip then rar.


WinZip Like all things file management, it will be obscure and strange at first. But file management does become easier as you practice. Definitely do try the WinZip tutorial above.
