#鸿蒙通关秘籍#如何将图片保存到系统文件管理器并展示保存路径？

通过PhotoViewPicker的save()接口将图片保存到系统文件管理器内特定目录，与图库管理的资源隔离。

1. 保存图片至文件管理器：

   const photoSaveOptions = new picker.PhotoSaveOptions();
   photoSaveOptions.newFileNames = ["PhotoViewPicker01.png"];
   const photoViewPicker = new picker.PhotoViewPicker();
   
   photoViewPicker.save(photoSaveOptions).then((photoSaveResult) => {
     const saveUris = photoSaveResult;
     console.info('File successfully saved, URIs: ' + saveUris);
   
     let photoSelect = fs.openSync(selectUris[0], fs.OpenMode.READ_ONLY);
     let photoSave = fs.openSync(saveUris[0], fs.OpenMode.WRITE_ONLY);
     fs.copyFileSync(photoSelect.fd, photoSave.fd);
     fs.close(photoSelect);
     fs.close(photoSave);
   }).catch((error) => {
     let err = error as BusinessError;
     console.error(`Failed to save file, code is ${err.code}, message is ${err.message}`);
   });
