I downloaded astro file manager and deleted it that way. Thanks.
On another note what else can you do with the file manager. Its great for me on deleting the pdf's like I just did but how else could it benefit me?
you can make folders for things, maybe you want to have a ring tones folders, or you want to seperate your music, or pictures, , make a family videos folder....you can also use it to sideload apps, maybe you are on our site and you see someone has a direct download to an app, you can download it and use astro to install the app.
