The Mini Gallery sample application demonstrates how you can handle content items and the device file system in your application.
The following figure illustrates the main screens of the Mini Gallery.
Figure: Mini Gallery screens
The Mini Gallery application opens with a preview of the folders on the device. To view the contents of a folder in the gallery view, click on the folder. To delete an image from the folder, click the image, and select Yes to confirm deletion.
Source Files
You can create and view the sample application project including the source files in the IDE.

| css/style.css | This file contains the CSS styling for the application UI. |
| images/ | This directory contains the images used to create the user interface. |

Implementation
The AttributeFilter() constructor constructs a new instance of the attribute filter by the specified parameters.
filter = new tizen.AttributeFilter('type', 'EXACTLY');
The SortMode() constructor constructs a new instance of the attribute filter by the specified parameters.
sortMode = new tizen.SortMode('title', 'ASC'),
The RefreshGalleries function invokes the find() method to find content using the specified filter and sorted by specified sort mode.
function refreshGalleries()
{
refreshed = false;
tizen.content.find(contentFindSuccess, contentFindError, null, filter, sortMode);
}
The following code presents how to delete a specified file from file system:
function deleteFile(fileUri)
{
tizen.filesystem.resolve(
resource,
function del(dir)
{
dir.deleteFile(resource + '/' + name, function scan()
{
tizen.content.scanFile(fileUri, function success() {}, function failed(e) {}),
},
function failed(ev) {});
},
function failed(e) {});
}
