When you leave Bossier Parish Schools as a student or a staff member, you can copy the contents of your Google Drive and transfer it to a personal Google account.   Google has a service called "Takeout" that allows you to download or transfer your files to another google account. 

Transfer is great as long as you have access to another google account that will hold the files you want to transfer but if you just want to download everything then just use the Google Takeout option without the transfer.

Takeout has several more options such as Map, Keep, etc. Takeout compresses your data into smaller blocks and you download everything to a local computer in one or more zip files.   You will have to unzip those files to access or reuse the data.  Zip files compress the data so it should take lass space for each type of item.  The storage to copy the required files is only limited by the free space on your computer or external drive. ou can pick and choose the Google data to download.   You may have to download them over a few days depending on how much data you have.

Important: This process only copies files you own. To copy files owned by others, open each file and create a personal copy. Note that these copied files will not update with changes to the originals, and shared member access will be removed.
