you can sent the document or the picture to the U disk through or sent it directly to other device through app.
beside the OTG cable can also transmit the data.

2.Go to Settings, Personal, Accounts & Sync, and select your Google account.

Syncing your data with your email is probably the best option to go. Any other way isn't exactly viable.

Or see Backing up an Android Device. It should include everything.
