After successfully installing 7zip, you are ready to create a compressed self-extracting archive using this software.

Step 2: Create a compressed archive

After downloading and installing 7zip, you can create your own compressed self-extracting archive. Follow these steps:

Step 1: Select the files to compress

First, select the files you wish to compress. You can select multiple files at once by holding down the Ctrl key and clicking on the desired files.

Step 2: Right-click on the selected files

After selecting the files, right-click on one of the selected files. In the drop-down menu, choose "Add to archive...".

Step 3: Configure compressed archive settings

In the "Add to Archive" dialog box, configure the following settings:

• Format: Select "7z" as the compression format.
• Archive type: Choose "Self-extracting" as the archive type.
• Under the "Compression" tab:
• Compression level: Choose a compression level between "Ultra" and "Normal".
• Encryption: Optional, you can set a password to protect the compressed archive.

Step 4: Create self-extracting compressed archive

After configuring compressed archive settings, click on the "OK" button to create a self-extracting compressed archive. The created file will have an ".exe" extension.

That's it! Now you have a self-extracting compressed archive that can be easily shared and used by other users without requiring specific decompression software.

Step 3: Set self-extraction options

After selecting the files to compress and setting the compression level, you can set self-extraction options for the created archive. Self-extraction allows recipients of the archive to automatically decompress the files without needing to install any additional software.

Step 1: Select the "Self-extracting" tab

From the main interface of 7zip, click on the "Self-extracting" tab. Here are several options that can be customized to create a self-extracting archive.

Step 2: Set default extraction path

In the "Extraction path" section, you can specify the default path where files will be extracted once the archive is opened. This option can be useful if you want recipients of the archive to save files in a specific location.

Step 3: Customize self-extraction icon

In the "Icon" section, you can customize the self-extraction icon. Click on the "Browse" button to select a custom icon from your computer.

Step 4: Set warning message

In the "Message" section, you can set a warning message that will be displayed before file extraction. This can be useful for providing instructions or important information to recipients of the archive.

Step 5: Set the password (optional)

In the "Password" section, you can set a password for the self-extracting archive. This will prevent unauthorized access to the files contained in the archive. It is important to choose a secure password and only share it with authorized persons who need access to the files.

• Type your desired password in the "Enter password" field.
• Repeat the password in the "Confirm password" field.
• Click on the "Add" button to confirm the password.

After setting all desired self-extraction options, click on the "OK" button to create the self-extracting archive.

Step 4: Customize the icon of the self-extracting archive

Now that you have created your self-extracting archive, you can customize its icon to make it more recognizable and attractive. Here's how:

Step 1: Find an image to use as an icon

First, choose an image that you want to use as the icon of your self-extracting archive. You can search online or create your own custom image using graphics software.

Remember that the icon must be in .ico format, so if you have chosen an image in another format, you will need to convert it. There are several free online tools that allow you to convert images to .ico format.

Step 2: Rename the icon with the same name as the self-extracting archive

After finding or creating the desired icon, rename it with the same name as the self-extracting archive. For example, if your archive is named "compressed_file.exe", rename the icon to "compressed_file.ico". Make sure both files are in the same folder.

Step 3: Add the icon to the self-extracting archive

Now you need to add the customized icon to your self-extracting archive. To do so, follow these steps:

• 1. Right-click on the self-extracting archive and select "Properties".
• 2. Select the "Customize" tab.
• 3. Click on the "Change icon..." button.
• 4. In the dialog box that opens, click on the "Browse..." button and select the customized icon that you renamed earlier.
• 5. Click "OK" to confirm the changes.

You have now successfully customized the icon of your self-extracting archive!
