Steps You Can Take

Step 1: Review content and file sizes in your NC State Google account.

Step 2:  If you are approaching or over your target quota, review the following services to reduce storage usage:



  • Your NC State Gmail should not be used for personal correspondence. If you are receiving personal email to your NC State account:
    • Visit each personal/consumer service and change your email address to a personal email address. 
    • Move any personal emails to trash.

  • Find old/unnecessary emails and move to trash.
    • Review the University Record Retention and Disposition Regulation.
    • Search your NC State Gmail account for messages that can be deleted. 
    • Narrow your search in Gmail by using additional Search Operators. Examples include:
      • Has attachment: attachment size > x query
      • Date: Older than x query – maybe 7 years?
      • Size: size > x query
    • Review the emails listed in your search results and delete if they are no longer needed for retention.  


  • Your NC State Google Drive should not be used to store personal files. 
  • If there are personal, non-NCSU items in Drive, copy them and then delete
  • Find old/unnecessary files and move them to the trash.
    • Narrow your search in Drive by using additional Search Operators. Examples include:
      • Date: Older than x query – maybe 7 years?
      • Size: size > x query
      • Owner = x
    • Check when the item was last modified/opened.
      • Highlight a file and look in right-side info panel to review when the file was last accessed. 
  • Visit the Drive Quota page to view your largest files
    • Determine if these are still needed
    • If not, move them to trash.
  • Identify items that are not collaborative in nature that still need to be kept, but do not belong in Google Drive.
    • Examples:
      • Research focused files
      • Backups / archive storage
    • Make note of the items, their purpose, and how often they need to be accessed. Then reach out to your local IT Staff to discuss alternative storage options..  
  • Use the Drive Inventory add-on
    • Identify large folders and duplicated files
      • Delete duplicates and replace them with shortcuts
