Android Studio は、Device Explorer で開かれたファイルを、プロジェクト外の一時ディレクトリに保存します。Device Explorer で開いたファイルに変更を加えて、変更内容を自分のデバイスにも保存したい場合は、ファイルの変更バージョンを手動でデバイスにアップロードする必要があります。

It's useful when examining files your app creates\nor if you want to transfer files to and from a device.\n| **Note:** Most device data is not visible unless you are using a rooted device or an emulator with a standard Android (AOSP) system image, not one of the Google APIs or Google Play system images. When using a connected device, be sure to [enable USB debugging](/studio/debug/dev-options#enable).\n\nTo work with a device's file system, proceed as follows:\n\n1. To open the Device Explorer, select **View \\\u003e Tool Windows \\\u003e Device\n Explorer** or click the **Device Explorer** button in the tool window bar.\n2. Select a device from the drop-down list.\n3. Interact with the device content in the file explorer window:\n - Right-click a file or directory to create a new file or directory.\n - Save, upload, delete, or synchronize the selected file or directory to your machine.\n - Double-click a file to open it in Android Studio.\n\n\n**Figure 1.** The Device Explorer tool window.\n\nAndroid Studio saves files you open in the Device Explorer in a temporary\ndirectory outside of your project. If you make modifications to a file\nopened using the Device Explorer and want to save your changes back\nto the device, you must manually upload the modified version of the file to the\ndevice.\n\nWhen exploring a device's files, the following directories are particularly\nuseful:\n\n`data/data/`\u003cvar translate=\"no\"\u003eapp_name\u003c/var\u003e`/`\n: Contains data files for your app stored on\n [internal storage](/training/data-storage#categories-locations).\n\n`sdcard/`\n: Contains user files stored on\n [external user\n storage](/training/data-storage#categories-locations) (pictures, etc.).\n\n**Note:** Not all files on a hardware device are\nvisible in the Device Explorer. For example, in the `data/data/`\ndirectory, entries corresponding to apps on the device that are not debuggable\ncan't be expanded in the Device Explorer."]]
