On iPhones and iPads, searching files is primarily done through the Files app. This app acts as a central hub to locate documents saved directly on your device, stored in iCloud Drive, or accessed from other cloud storage services like Google Drive or Dropbox when they are integrated. Unlike traditional computer file searches that browse entire disks, iOS searches focus on the locations accessible within the Files app's ecosystem. You simply open Files and use its built-in search function.

To search, open the Files app and tap the search bar at the top. Start typing the name of the file or folder you need. For instance, if you remember a presentation is called "Budget_Q1," typing "budget" will display related files across your locations. Similarly, searching for "invoice.jpg" can locate a specific image saved in iCloud Drive. You can also start a search directly within specific apps supporting this feature; for example, search within the Mail app for an attachment you downloaded.

This integrated search offers quick access without needing to navigate complex folder structures, significantly improving efficiency for common file retrieval tasks. However, its effectiveness depends on files being stored within services accessible to the Files app and requires some recall of the filename. It generally doesn't search inside file contents unless using specialized apps like Apple Notes or PDF viewers. Future updates may enhance content indexing and relevance.
