So you might have gone with the 8GB Nexus 7 instead of the 16GB and why not? It's $50 cheaper and how many things do you need to have on the device when your movies, music, magazines, etc. are all in the cloud through Google Play? That's a sound theory, but perhaps you managed to fill up those 8GBs regardless. To get more space, you can either delete things, or you can use Google Drive to move some of them off the tablet and store them in the cloud. Here's how.
1. Open the Play Store on your Nexus 7.
2. Search the store for Google Drive, select it and install it.
3. Search the store, again, but this time for ES File Explorer. We need this so we can upload any file we want to Google Drive.
4. Open Google Drive.
5. Select the upload icon in the top right corner.
6. Select ES File Explorer.
7. Select whatever files you want to upload to Google Drive and then delete them from the device once they are confirmed to be uploaded. Now you have at least another 5GBs of storage from Google Drive for free.
