One of the wonderful thing that WordPress did in the upgraded version of WordPress since 2.5x is to add support for storing popular video, image and document files. This feature together with generous free storage space of 6GB provided by WordPress.com provides a highly integrative and reliable solution in managing blog and its resources.
Note: Those file support limitation could be circumvented by renaming the file to those supported extension. For example, if one want to upload a file name myfile.xar which is unsupported file type, just renamed it to any of the type. Suggest to rename as doc to prevent Browser from executing those file directly, resulting in error. For doc type, the browser usually display a Save As dialog (depending on setting).
Allowed file types: jpg, jpeg, png, gif, pdf, doc, ppt, odt, mp3, mp4, m4a, wav, ogg, mov, wmv, avi, mpg
The following provides a step-by-step guide to storing file in WordPress.
To add a file, go to Write->Post tab. The Write screen is also where one add the file even though one might not write a post. Under the Add media button selection, choose anyone of them as they bring up the same Upload Screen.
Click any of the Media button.
The Upload Screen will popup. Choose the file and click on Upload button and the uploading begin immediately.
As soon as upload is done, the following Detail screen will appear. Depending on the file type uploaded, more options will appear. For example, Alignment and Size option will appear for image file but not document file. Copy LINK URL so that this file can be used in a post.
In addition, under Media Library tab of the same screen, a listing of all resources used in blog post or uploaded will be shown. In this screen, user can click on the Show link to display Detail screen. This is very useful to get the LINK URL. In this screen, the resource can also be deleted using the Delete link.
Another screen that might be useful is the Manage Media screen where it allows one to perform batch delete, check which file is used by respective post. Note that file that manually insert to blog post will not be associated to the post. For example, if one insert a file link using a blog editor, this will not be registered with the post as shown in Appears with column.
Using the LINK URL
Associate the file URL with image or anchor in a post.
