1. Extract the RAR Archive:
Begin by extracting the RAR archive using software like WinRAR or 7-Zip. This will decompress the contents of the archive.
2. Locate Your Portal Directory:
Navigate to your Portal directory on your computer.
3. Open the Portal Folder:
Inside the Portal directory, open the "portal" folder. This will take you to the following path: `...\common\portal\portal`.
4. Rename the Maps Folder:
Find the "maps" folder within the second portal folder and rename it to your desired name. For instance, you can rename it to "defalt maps" or any other name you prefer.
5. Rename the Demo Maps Folder:
Locate the "demo maps" folder and rename it to "maps".
6. Organize the New Maps Folder:
Ensure that the contents of your renamed "maps" folder are structured correctly. Make sure the `.bps` files and other associated files are located at the top level of the folder, not nested within subfolders. This will result in the following directory structure: `...\common\portal\portal\maps`.
By following these steps, you will have successfully installed and organized my custom map pack for Portal.
