I can't download movies,apps as to says I don't have enough storage space.i have close to 50 gb,have tried managing settings,what can I do?

I had tried a half dozen "2SDcard" type apps as well as half dozen file/apps managers which I downloaded from the Google Play Store. None of them even recognized the SD card I had in my Dell Venue 8. And while the Dell "Settings-storage" did show there was a 32 GB card there none of the apps I tried found it. And that is with both my original tablet and the "refurbished" tablet Dell sent me because they were unable to fix my original Tablet. So since it became clear that Dell was not going to help me with their product, I returned my Dell Venue 8 to Office Max for a full refund. So I guess I would have to comment that: 1. If Dell is going to provide an SD card slot, why not provide the correct software or hardware to allow for its use. 2. If all I needed to do was install an app called "ES Explorer" why didn't the Dell Tech tell me that? They are supposed to be the experts, not me. (As I no longer have the tablet I cannot try your suggestion so don't know if the 13th app I might have downloaded would work or not.) But I do want to thank you. Your post was more helpful to me than the four different Dell Techs I spoke with

is it possible you have a partition on your storage and are attempting to download in the smaller section of the patrician,

storage memory is low for one particular item
the 12 GB is all free space
you can decide how the 12 GB is to be used

Most likely your iPad is full... of pictures, videos, music, etc. Visit the Settings app, tap General, then Usage. In the STORAGE section at the top, you'll see how much of the storage is available on your iPad and how much is used. If the available number is small, you need to remove stuff until you have enough to handle incoming video streams (YouTube, for example).

The STORAGE section also identifies the apps that are using your space - if Music, Photos & Camera, or other apps seem to take a large portion of the space, either remove some of the data associated with those apps (pictures, movies, music) or remove apps themselves (apps you don't use don't need to be taking space on your iPad).

Portable devices aren't meant for large permanent storage. You should save things you intend to keep forever on your desktop device or in the cloud.

Move your apps to the SD card via Settings - Apps. You have to move each app one at a time, and some will not move. Then clear your browser cache. Delete old messages, especially ones with photos and videos with them.

Go to your settings. Then to your apps. When you click on the app, you will have the option move to your sd card. Do it. Do the same with your photos, videos and music files. That is what your Sd Card is for. Once this is done you will have plenty of space on your internal memory to download what you want.

Hi Anonymous,
This might help you, just follow these:
1. Go to your iPad's home screen by clicking on the home button. Click on Settings to access your settings.
2. Go to General in Settings and click on Usage. This will allow you to manage your storage, as you'll see a list of what's stored on your iPad. Look at how much storage you have available. This will inform you how much you need to get rid of, but not too much because you still have plenty of space.
3. Click on Manage Storage to start managing your storage. See what apps you have and how much space they take up. If any apps take up a lot of space, and you don't need them any more, you know you need to delete them.

4. Delete unwanted apps. To delete an app: •Tap on the relevant app in the list. You will see the button Delete App. You will also see the app's size and its Documents and Data usage (including data cached for quick access).
•Tap on the Delete App button, and the app will be deleted. •Note that the apps that come pre-installed (such as the Music and Videos apps) cannot be deleted.
•Take care not to delete any apps you need, especially for work. Instead, make room for them by determining which apps you no longer use or want (such as games, PDFs or other items you've finished with).

Tablets have internal storage and external SD cards (optional) storage. Apps will download to the internal storage. So under Settings > Storage make sure you have space on your internal storage.

That system warning relates to available application space. For some reason Archos only devoted ~128 MB for applications, so you can fill that up pretty fast. You'll need to:
uninstall applications (settings, Applications, Manage Applications, then select and uninstall some)
or
move some applications to "internal storage", this transfers some of the space they're taking to the internal storage on your Archos. Again you'll go to Settings, Applications, then Manage Applications. From the list of applications select some of the larger ones and you may see a "move to internal storage" option. Some apps have this, some don't.
