1. Copying the Engine Files

[Note] In this example, the engine file is extracted to the examples/bin/ directory to share it with other examples. However, for actual deployment, the engine file is typically copied to the directory where the application’s executable file is located.

For Windows x86 64-bit Extract the engine file to the examples/bin/linux-x86_64 directory
```
tar xvf tsanpr*-linux-x86_64.tar.xz
```
For Windows x86 32-bit Extract the engine file to the examples/bin/linux-x86 directory
```
tar xvf tsanpr*-linux-x86.tar.xz
```
For Linux x86 64-bit Extract the engine file to the examples/bin/linux-x86_64 directory
```
tar xvf tsanpr*-linux-x86_64.tar.xz
```
For Linux arm 64-bit Extract the engine file to the examples/bin/linux-aarch64 directory
```
tar xvf tsanpr*-linux-aarch64.tar.xz
```
