You will probably use the file manager a lot as you update your website's content, mostly to add images to your pages and make files available to people browsing your website.
If this is your first time using the BMS, you need to decide how you want to have your images resized before you place them on your pages. If you do not resize images and add them as they are when they come out of your camera, they will have a huge file size and will slow down your web pages, potentially negatively affecting your ranking on search engines.
You can either resize images on your computer, before uploading them to the file manager, or you can let the file manager do that for you automatically.
If you would like the file manager to do it for you, it needs to be set-up correctly. For that, go to "admin" => "site configuration" and make sure that the box to "resize new images" is ticked. Scrolled down and click on the "update" button. You will then need to logout and login again, to make sure this setting is activated in this session. You will not need to do that again at future sessions.
Activating this feature means that, whenever you upload a large image, the file manager will create multiple smaller versions of it so that you can place the most appropriate one on your page.
To see how this works, let's open the file manager and upload a large image...
To upload a file from your computer, go to the folder in the file manager where you would like to store the file and then click on "upload". Look for the file on your computer and select it.
As you see, the file manager has created multiple versions and added the sizes to the file names so that you can easily select the right one.
You can also work with your files from within the file manager. For example, you can rename them, move or copy them to another folder and use some basic editing tools.
When renaming your files, you should make sure that the file names contain letters and numbers only, with the possible addition of hyphens or underscores, nothing else and no spaces. Of course, there should always be a dot before the file extension, but that is the exception.
