If I delete a software (game) from data management, in Nintendo Switch settings in Nintendo Switch how many days or weeks and months , before I can reinstall the software on Nintendo Switch but what is the recommended time
When you delete a game from your Nintendo Switch, it is immediately removed from your system, and you can reinstall it at any time without any waiting period. If you've purchased the game digitally, it will remain linked to your Nintendo account, and you can redownload it from the Nintendo eShop.
There’s no recommended waiting time before reinstalling; you can do so right away. However, if you have a limited internet connection or data plan, you may want to consider the size of the game and any updates required before reinstalling.
