## Concepts

- [Files manager](https://developer.huawei.com/consumer/en/doc/harmonyos-references/js-apis-file-fs): provides APIs for file operations, including accessing and managing files and directories, obtaining file information, and reading and writing data using streams. (**@ohos.file.fs**)
- [Picker](https://developer.huawei.com/consumer/en/doc/harmonyos-references/js-apis-file-picker): encapsulates APIs such as **DocumentViewPicker**, and **AudioViewPicker** for you to pick and save files. (**@ohos.file.picker**)
- [Photo manager](https://developer.huawei.com/consumer/en/doc/harmonyos-references/js-apis-file-picker): provides the photo management capabilities, including creating an album, and accessing and modifying media data in the album, and **PhotoViewPicker**. (**@ohos.file.photoAccessHelper**)
- [PhotoViewPicker](https://developer.huawei.com/consumer/en/doc/harmonyos-references/js-apis-file-picker#photoviewpickerdeprecated): allows you to pick and save images and videos.
- [DocumentViewPicker](https://developer.huawei.com/consumer/en/doc/harmonyos-references/js-apis-file-picker#documentviewpicker): allows you to pick and save documents in different formats.
