A 4GB storage capacity can hold approximately 4 gigabytes of data, which translates to about 4,000 megabytes. This means you could store around 1,000 songs (assuming each song is about 4MB), around 1,000 photos (if each photo is about 4MB), or a few hours of standard-definition video. The actual amount of data that can be stored may vary depending on the file types and their sizes.

Persistent data can either be stored in the registry, in an INI file, or in any data file. Data related to the program itself (configuration data) should be stored in the registry or an INI file. The registry is the preferred option, using the HKEY_LOCAL_MACHINE hive for data related to all users and the HKEY_CURRENT_USER hive for the current user only. INI files were originally intended for 16-bit applications and are best avoided unless you have good reason to use them. For all other data (application data), use a data file.
A collection of data stored in one unit and identified by a file name is referred to as a file. Files can contain various types of information, such as text, images, audio, or structured data, and are typically organized in a file system on a storage medium. Each file is associated with a specific format that determines how its contents are structured and accessed.
