What is an APP file?
An APP file is an application bundle that runs under macOS, an operating system (OS) developed by Apple and designed to run on Macintosh computers. It stores multiple directories, such as Contents, Resources, and Frameworks, which contain various files that make up the application. APP files are executable files similar to .EXE files in Windows and run when double-clicked.
Because APP files are macOS packages, you can right-click (or control-click) an application and select 'Show Package Contents' to view the files contained in the package. These include resources used by the application, executables, property list (.PLIST) files, frameworks, plugins, icons, and other files.
In Windows and Linux systems, it may be possible to view the contents of a macOS application as if it were a folder. A decompression program like WinRAR may also be able to extract files from a macOS application on other operating systems.
NOTE: Files within an application package should not be edited or moved, since changes may prevent the program from running correctly.

.APP File Association 4
An APP file contains encrypted data dumped from a Nintendo Wii U video game. It stores a section of the game data, along with other APP files, that when decrypted and pieced together, can be opened and played on a computer using a Wii U emulator.
APP files are used by gamers who enjoy playing and altering Wii U games on their computers. Since APP files contain pieces of a Wii U game to reduce file sizes, all the APP files need to be present in order to play the Wii U game.
Also, Wii U APP files are encrypted and must be decrypted before they can be opened and played. A Title Metadata .TMD file, which stores metadata and the title key for the APP game, is required in order to decrypt the APP file.
APP files are named according to the number of files to which the game data was split. The files start at 0 (00000000.app), then increase from there to 00000001.app, 00000002.app, etc.

.APP File Association 5
An APP file is an archive used by a downloaded Nintendo Wii channel, or .WAD file. It contains application or game data compressed using Yaz0 or LZ77 compression and saved in the U8 archive format. APP files are typically not meant to be opened.
The Nintendo Wii gave players access to an online marketplace called WiiWare, which they could use to download additional games and applications for their console. The Wii downloaded these games and applications as WAD files which, when installed, became new Nintendo Wii channels. Each WAD file included a handful of compressed APP archives, which contained files used to install and access the new channel.
Nintendo discontinued the WiiWare marketplace at the beginning of 2019. However, homebrew gamers and Wii emulator users still use WAD files and the APP files contained within them to install Wii games and other applications.
How do I open an APP file?
Typically, Nintendo Wii players should not open the APP files included within a WAD file. However, homebrew gamers and emulator users may wish to view or extract the files contained within a channel's APP archives. To do so, you can decompress the archive using a U8 decompression tool, such as U8 Tool or Sharpii.

The best place for all your photos, files, and more.
iCloud is built into every Apple device. That means all your stuff — photos, files, notes, and more — is safe, up to date, and available wherever you are. And it works automatically, so all you have to do is keep doing what you love. Everyone gets 5GB of free iCloud storage to start, and it’s easy to add more at any time.
iCloud Photos
All your photos and videos.
Always available.
A lifetime of photos
on all your devices.
With iCloud Photos, you can browse, search, and share all the photos and videos from any of your devices, whether they were taken yesterday or years ago.
Take all the photos you want. Without worrying about space on your devices.
To save space on your devices, the original, full‑resolution photos you take are automatically uploaded to iCloud. You’ll still always have a lightweight version of every photo on your device, and you can download the originals whenever you need them.
All your files available from all your devices.
The files you keep safe in iCloud Drive are easy to get to, no matter which device you’re using. You can access all your files from the Files app on iOS and iPadOS, the Finder on your Mac, File Explorer for Windows PCs, or iCloud.com.
Organize files however you want. Get to them on any device you want.
iCloud Drive lets you organize your files with folders, rename them, and tag them with colors. And when you make a change, the update is made across all your devices. You can even have everything in your Mac Desktop and Documents folders automatically available in iCloud Drive.
Apps using iCloud
Your favorite apps are
even better with iCloud.
All your essentials.
Accessible from all your devices.
iCloud automatically keeps apps — including Mail, Calendar, Contacts, Reminders, Safari, and some of your favorite apps from the App Store — updated across all your devices. So when you add a new phone number, bookmark a website, or update a slide in a presentation, the change appears everywhere.
Collaborate with Pages, Numbers, Keynote, and Notes.
Work with others on documents, presentations, and spreadsheets and see edits as they’re made. With live updates on all your devices, your collaborators will always be on the same page.
Every message. Updated across all your devices.
iCloud automatically stores all of your messages. Search for an address, a funny exchange, or anything else. And you can pick up every conversation right where you left off. Even when you move to a new phone or computer.
iCloud Backup and Restore
All the things that matter.
Safe and secure.
Automatic backups give you peace of mind.
iCloud automatically backs up your iOS and iPadOS devices when they’re connected to power and Wi-Fi. So if you lose your device or get a new one, you’ll have all the things that matter without missing a beat.1
Move to a new device with everything you loved about your old one.
iCloud makes moving your settings, photos, apps, and documents to a new device seamless. Just sign in to iCloud when you set up your new device, and you’ll be ready to go in minutes.
Two‑factor authentication helps keep your data safe.
Two‑factor authentication is an extra layer of security designed to ensure that only you can access your account. That means your account can only be accessed on devices you trust, like your iPhone, iPad, or Mac.
Android File Transfer App For Mac
Find the storage plan that’s right for you.
The right amount of storage depends on how you and your family members want to use your devices. Everyone gets 5GB of free iCloud storage to get started and it’s easy to upgrade at any time. Your apps and any iTunes or Apple TV purchases don’t count toward your iCloud storage space, so you need it just for things like photos, videos, files, and device backups.
Good for safely storing all the basics, like contacts, calendars, and notes.
Recommended for storing your photos, videos, files, and apps and backing up your device.
