If the built-in file manager doesn’t have the feature to extract the ZIP file, then you can use a third-party app. Just go to the location where you have downloaded the file, then select it and find the Extract option. For this task, you can use the built-in file manager of your phone. If the sample pack is in a ZIP compressed file, then you have to unzip it first.
