-# Extracting Split 7z Archives on Linux
-
-This guide explains how to extract a split `.7z` archive (e.g., `STAR.tar.7z.001`, `STAR.tar.7z.002`, ...) on Linux.
-
-## Prerequisites
-
-Make sure `p7zip` is installed on your system. You can install it using one of the following commands based on your distribution:
-
-- For **Ubuntu/Debian**:
-    ```bash
-    sudo apt update && sudo apt install p7zip-full
-    ```
-- For **CentOS/RHEL**:
-    ```bash
-    sudo yum install p7zip p7zip-plugins
-    ```
-- For **Arch Linux**:
-    ```bash
-    sudo pacman -S p7zip
-    ```
-
-## Steps to Extract
-
-1. **Navigate to the directory** where your split `.7z` files are located:
-    ```bash
-    cd /path/to/your/files
-    ```
-
-2. **Extract the `.7z` archive**:
-    To extract the archive, run:
-    ```bash
-    7z x STAR.tar.7z.001
-    ```
-    > **Note:** You don't need to extract `.002`, `.003`, etc. separately. Starting with `.001`, `7z` will automatically handle the rest of the parts.
-
-3. **Extract the resulting `.tar` file**:
-    After extracting the `.7z` files, you'll have a `STAR.tar` file. To extract it, run:
-    ```bash
-    tar -xvf STAR.tar
-    ```
+# How to Extract Split Archive Files on Ubuntu
+
+To extract a split archive (e.g., `STAR.7z.001`, `STAR.7z.002`, etc.) on Ubuntu, follow these steps:
+
+---
+
+## **Step 1: Install `p7zip`**
+If `p7zip` is not already installed, use the following commands to install it:
+```bash
+sudo apt update
+sudo apt install p7zip-full
+```
+
+---
+
+## **Step 2: Verify Split Files Are in the Same Directory**
+Ensure all split files (`STAR.7z.001`, `STAR.7z.002`, etc.) are in the same folder.
+
+Example directory structure:
+```
+/path/to/your/files/
+├── STAR.7z.001
+├── STAR.7z.002
+├── STAR.7z.003
+├── STAR.7z.004
+└── STAR.7z.005
+```
+
+---
+
+## **Step 3: Extract the Split Archive**
+Run the extraction command starting from the first split file (`.001`):
+```bash
+7z x STAR.7z.001
+```
+
+**Command Explanation**:
+- `7z`: Invokes the 7-Zip utility.
+- `x`: Stands for "extract".
+- `STAR.7z.001`: The first split file. 7-Zip will automatically detect and merge subsequent splits (`.002`, `.003`, etc.).
