Finding files by their addresses in Java

Creator QR Code 2d barcode in Java Finding files by their addresses

If you re not sure where you saved a file or what you called it, but you can get to it with your browser, you can determine the filename and location by looking at the URL in the browser s address bar Each folder in a Web site is included in the address to a page within that folder Folder names are separated by the forward slash /, and each filename can be distinguished because it includes an extension For example, the address to the page displayed in the figure tells me that the file is named dwfdhtml and that it is located in a folder called books

Similarly, you can identify the name and location of any image you are viewing on a Web page If you re using Internet Explorer, place your cursor over the image and right-click (Windows) and then choose Properties from the drop-down list The Properties dialog box includes the specific URL of the image, which has the name and folder (path) In this example, the image is named tipsgif and it s stored in the images folder If you re using the Safari browser on a Mac, it works a little differently Control+click an image and choose Open Image in New Window from the drop-down list In the new window, the image URL appears in the location bar

Many HTML teachers and consultants suggest that you place all your images in a single folder at the top level of the directory structure and name it images You may also find that other HTML authoring tools place all your images in one folder by default Dreamweaver doesn t require an images folder, but it does encourage you to identify a main images folder when you set up your site (for more on site setup, see 2) The advantage of keeping all your images in one folder is that you only have one place to look for them However, if all your images are in one place, you ll likely end up with a long list of image files, making it harder to keep track of which image is which When you want to change an image later, sorting through this list can be arduous work A good alternative is to store your images in multiple images folders and keep them within subfolders with related HTML files For example, keep all your staff photos for your staff pages in an images folder within a staff subfolder If you have images that link throughout the site a logo, for example you may want to keep those images in an images folder at the top level of your directory structure This way, the images are easy to find from any folder in the site Dreamweaver makes no distinction between a folder called images and a folder called hot-stuff, or any other name for that matter You can name your folders whatever you like, even goofy_pictures, just make sure you remember what you called them so you can find them again later

Part II: Looking Like a Million (Even on a Budget)

As you develop your site, the links only become more complicated to manage and easier to break Fortunately, Dreamweaver includes a variety of tools that help you keep links in good working order

You can use the Files panel to rename and rearrange files and folders, as well as create new folders, all with drag-and-drop ease You need to define your site for this to work (see 2) To rename or rearrange files, follow these steps: 1 Select the site name from the drop-down list at the top of the Files panel and choose the site you want to work on from the list When you select a site, the folders and files of that site display in the Files panel on the right side of the Dreamweaver work area 2 Use the plus (+) and minus ( ) signs to open and close folders in the Files panel 3 In the Files panel, select the file or folder that you want to change (move and/or rename): To move the selected file: Drag that file or folder anywhere in the panel For example, you can move a file into a folder, and Dreamweaver automatically changes all the related links This panel works just like the Explorer window on a PC or the Finder on a Mac, except that Dreamweaver tracks and fixes links when you move files through the Files panel By contrast, if you move or rename site files or folders in the Finder or Explorer, you break the links in existing Web pages In Dreamweaver, when you move a linked file into a new folder, the Update Files dialog box appears with a list of links that need to be updated, as shown in Figure 3-1 To adjust the links, choose Update If you choose Don t Update, any links to or from that file are left as they are, and likely won t work any more To rename a selected file: Click the selected file, and after the cursor appears at the end of the filename, type your new filename or edit the existing name When you finish, press Enter (Return on a Mac) Again you re prompted to update any links affected by the filename change Choose Update to adjust the links
