HELP- How can I delete hidden files on iPad that are taking up space?

[plasmo]

If anyone could help, it would be much appreciated:


I used a video App called gplayer (i already tried to contact them) to move several large video lectures (about 30GB) via wifi FTP to my iPad so that I could play the files using gplayer directly off the iPad (which worked VERY well)....

...until gplayer had an update, and now for some reason I guess their filestructure changed, so my previous videos are no longer seen
(yet I now still physically on the iPad taking up 30GB space!)

Now, I need to find those files and DELETE them so I can free up the space...unfortunately I cannot find them using Windows File Explorer (I checked all 100 folders in the DCIM folders...which only had my photos).
I tried to email gplayer support, but they haven't given me a reply yet.

Does anyone know a way to view the full iPad file structure, and find the "hidden" files so I can delete them off my iPad?
I know the files are there, as under my Settings/General/About icon,
the "Videos" section shows that there are "60" files.
(I don't have any Videos in the Videos App or ever used iTunes to upload videos)

Thanks for any help!!!

Delete the app and reinstall it. That's the only thing you can do unless you are jailbroken.

I already tried deleting the app, and reinstalling it.
No my ipad is not jailbroken.

thanks for replying though.
I'm pretty sure the files are tucked away somewhere in the file system, but Apple makes it difficult to access this...

The files are kept within the app's working directory. Deleting the application will remove the working directory and all of its contents.
