Preview files and folders

You can quickly preview files without opening them in a full-blown application. Select any file and press the space bar. The file will open in a simple preview window. Press the space bar again to dismiss the preview.

The built-in preview supports most file formats for documents, images, video, and audio. In the preview, you can scroll through your documents or seek through your video and audio.

To view a preview full-screen press <key>f</key>. Press <key>f</key> again to leave full-screen, or press the space bar to exit the preview completely.

Open the <gui>Launcher</gui> and then click the <app>Trash</app> shortcut which is located at the bottom of the Launcher.

You can also choose <gui>Eject Anyway</gui> to remove the device without closing the files. This may cause errors in applications that have those files open.

On some file systems, file names can have no more than 255 characters in their names. This 255 character limit includes both the file name and the path to the file (e.g., <file>/home/wanda/Documents/work/business-proposals/… </file>), so you should avoid long file and folder names where possible.

Click the magnifying glass in the toolbar, or press <keyseq><key>Ctrl</key><key>F</key></keyseq>.

Type a word or words that you know appear in the file name. For example, if you name all your invoices with the word "Invoice", type <input>invoice</input>. Press <key>Enter</key>. Words are matched regardless of case.

You can narrow your results by location and file type.

Click <gui>Home</gui> to restrict the search results to your <file>Home</file> folder, or <gui>All Files</gui> to search everywhere.

Click <key>+</key> and pick a <gui>File Type</gui> from the drop-down list to narrow the search results based on file type. Click the <key>x</key> button to remove this option and widen the search results.

Click the magnifying glass in the toolbar again to exit the search and return to the folder.

Transfer files to your email contacts from the file manager.

You can share files with your contacts or transfer them to external devices or <link xref="nautilus-connect">network shares</link> directly from the file manager.

You can sort files in different ways in a folder, for example by sorting them in order of date or file size. See <link xref="#ways"/> below for a list of common ways to sort files. See <link xref="nautilus-views"/> for information on how to change the default sort order.

The way that you can sort files depends on the <em>folder view</em> that you are using. You can change the current view using the list or icon buttons in the toolbar.

To sort files in a different order, click the <media type="image" src="figures/go-down.png">down</media> button in the toolbar and choose <gui>By Name</gui>, <gui>By Size</gui>, <gui>By Type</gui> or <gui>By Modification Date</gui>.

As an example, if you select <gui>By Name</gui>, the files will be sorted by their names, in alphabetical order. See <link xref="#ways"/> for other options.

You can sort in the reverse order by selecting <gui>Reversed Order</gui> from the pull-down menu.

In list view, you can show columns with more attributes and sort on those columns. Click the <media type="image" src="figures/go-down.png">down</media> button in the toolbar, pick <gui>Visible Columns</gui> and select the columns that you want to be visible. You will then be able to sort by those columns. See <link xref="nautilus-list"/> for descriptions of available columns.

Right-click anywhere in the empty space in the folder, then choose <gui style="menuitem">New Document</gui>. The names of available templates will be listed in the submenu.

These files are hidden by default. If you are seeing them, that is because you either selected <gui>Show Hidden Files</gui> (in the <media type="image" src="figures/go-down.png">down</media> menu of the <app>Files</app> toolbar) or pressed <keyseq><key>Ctrl</key><key>H</key></keyseq>. You can hide them again by repeating either of these steps.

Make sure that the card is put in correctly. Many cards look as though they are upside down when correctly inserted. Also make sure that the card is firmly seated in the slot; some cards, especially CompactFlash, require a small amount of force to insert correctly. (Be careful not to push too hard! If you come up against something solid, do not force it.)

Open <app>Files</app> by using the <gui>Dash</gui>. Does the inserted card appear in the <gui>Devices</gui> list in the left sidebar? Sometimes the card appears in this list but is not mounted; click it once to mount. (If the sidebar is not visible, press <key>F9</key> or click <guiseq><gui>View</gui><gui> Sidebar</gui><gui> Show Sidebar</gui></guiseq>.)

Add input sources and switch between them.

Use alternative input sources

Some languages, such as Chinese or Korean, require a more complex input method than just a simple key to character mapping. Consequently some of the input sources you can choose between enable such a method.
