 UniFile 是基于 `android.support.v4.provider.DocumentFile`，而且更好用。
 
+The UniFile is forked from `android.support.v4.provider.DocumentFile`, but more powerful.
+
 区别有：
-* 添加 listFiles(FilenameFilter)
-* 添加 openOutputStream()，openOutputStream(boolean)，openInputStream()
-* 添加 createRandomAccessFile(String)
-* 添加 subFile(String)
 * 添加其他文件 uri 支持
+    * 支持所有 ContentProvider 的 uri
+    * 支持 asset 文件的 uri，如 `file:///android_asset/text/uccu.txt`
+    * 支持 resource 文件的 uri，如 `android.resource://com.hippo.unifile.example/2130903040`
+* 添加 getFilePath()
+* 添加 listFiles(FilenameFilter)
+* 添加 openOutputStream()，openOutputStream(boolean append)，openInputStream()
+* 添加 createRandomAccessFile(String mode)
 * 删除了 createFile 中 mimeType 参数
 * 修改 createFile，createDirectory 特性，避免出现文件名后添加 (1) 的现象
