How to Sort Gmail Messages by Size


What do you do when your Gmail account storage is nearly full? You can either purchase additional storage space from Google – they charge $5 per year for 20 GB – or a cheaper alternative would be that you scan your Gmail mailbox for messages that contain large file attachments and delete (or forward) all the bigger messages and recover precious space.
The problem is how do you find these bulky messages in your mailbox when Gmail doesn’t offer an option to sort and filter messages by size?
gmail sort by size

Sort GMail Messages by Attachment Size

What we use is a simple Google Sheet that connects to Gmail, computes the size of individual messages and lists the bulky ones (size > 1MB) in the same Sheet. Here’s how you can get started:
  1. Create a copy of the Gmail Sort Google Sheet in your Google Drive.
  2. Click Scan Mailbox under the Gmail menu and authorize to let the script access your Gmail Inbox. It is an open-source Gmail Script that runs in your own Drive.
Sit back and relax as the script will pull the message list in the sheet. If the process stops for some reason, click Scan Mailbox again and the script will resume scanning from where it left off.
Once the sheet has a list of all the bulky message, you can sort the sheet by theSize column to find the big ones. Or use the Filter option (the Funnel icon) to find messages that are within a particular range (5 MB < size < 10 MB). Click the “View” link to open the corresponding message in Gmail, bulk auto-forward the big email to another email address or use the Save Emails add-on to download the big emails and attachments to your Google Drive.
Troubleshooting tips: If you get an error that says “Service invoked too many times for one day” or “Exceeded maximum execution time”, you may want to wait for some time before re-running the program. These are Google Apps Script limits to prevent abuse.

Sort Gmail Messages by Size with a trigger

If your Gmail mailbox is large, you can also set up a time-driven trigger to let the script run automatically without manual intervention. In this case, you can even close the browser tab and the script will run in the background. Here’s how:
  1. While the Google sheet is open, go to Tools -> Script Editor. On the next screen, choose Resources -> Current Script Triggers.
  2. Click “Add a New Trigger,” change the Event from “Spreadsheet” to “Time Driven” and set a minutes timer that triggers every 10 minutes.
  3. Save the trigger, authorize the script if it requires and close the sheet.

# yum install httpd mysql-server mysql-client php php-mysql php-curl

Step 2: Create Cloud Database

Once you setup LAMP stack on your personal box, just login to your database (MySQL, here).
# mysql -u root -p
Enter mysql root password. Now we will be creating a database (say cloud).
mysql> create database cloud ; 
Query OK, 1 row affected (0.00 sec)
It is not a good idea to access your database from root, hence grant all the permission to a normal user (say tecmint).
mysql> grant all on cloud.* to tecmint@localhost identified by 'my_password'; 
Query OK, 0 rows affected (0.00 sec)

Step 3: Download and Install ownCloud Application

Now its time to Download latest ownCloud (i.e version 8.0.0) application using below link.
  1. http://owncloud.org/install/
Alternatively, you may use wget command to download the source tar-ball package.
# wget https://download.owncloud.org/community/owncloud-8.0.0.tar.bz2
You may alternatively install from source package using APT or YUM. The installation instruction can be found at:
  1. Install ownCloud using APT or YUM
However we choose the TAR package which is universally accepted and works on most of the known system.
After Downloading the owncloud package, move it to your Apache working directory, which is /var/www (for Debian) and /var/www/html (for RedHat).
# cp owncloud-8.0.0.tar.bz2 /var/www/  [For Debian based Systems]
# cp owncloud-8.0.0.tar.bz2 /var/www/html/ [For RedHat based Systems]
Next, extract the package using tar command as shown below.
# tar -jxvf owncloud-8.0.0.tar.bz2
Since the TAR Archive is extracted you may remove the Archive.
# rm -rf owncloud-8.0.0.tar.bz2
We might need to change the file permission of owncloud, in our Apache working directory.
# chmod -R 777 owncloud/
Note: Remember we are giving read, write and execute permission to all, which is although risky but this time needed since several configuration file would be written automatically. We later need to change permission to 755, once the setup is finished.

Step 4: Configuring Apache for ownCloud

For security purpose ownCloud uses Apache‘s .htaccess files, in order to use them. We need to enable two Apache modules mod_rewrite and mod_headers for ownCloud to function properly. Type the following command to enable these modules under Debian based systems only, for RedHat systems they are enabled by default.
# a2enmod rewrite
# a2enmod headers
Additionally, we need to enable mod_rewrite rules to work properly under Apache‘s main configuration file. Open the Apache global configuation file.
# nano /etc/apache2/sites-available/default [For Debian based Systems]
# vi /etc/httpd/conf/httpd.conf   [For RedHat based Systems]
There, find “AllowOverride None” and change this to “AllowOverride All” as shown.
AllowOverride None
Change this to:
AllowOverride All
Now we need to restart Apache to reload new changes.
# service apache2 restart   [For Debian based Systems]
# service httpd restart    [For RedHat based Systems]

Step 5: Access ownCloud Application

Now you can acess your very personal cloud storage at:
Once you get the Owncloud page, you need to create an admin account and a Data folder location, where all files/folders will be stored (or leave default location i.e. /var/www/owncloud/data or /var/www/html/owncloud/data). Next, you need to enter mysql database username, password and database name, refer the screenshot below.
Once all the correct values are entered, click Finish and your private cloud storage is ready, you are greeted with the working interface:
Notice the Favorites, edit, share, download, upload and new file options available for a file.
Activities log of oneself and others.
Pictures library.
Apps enable and disable interface as well as recommendation with brief introduction.
Inbuilt PDF reader.
From this admin panel you can view security and setup warnings, Fedrated cloud sharing, Mail Templates,
Updater, Cron, sharing, Security, Email Server, Log, etc.
User and Group information with quota.
Note: You can add users or imports user account, change password, assign user role and allocate space by clicking the Gear icon on left bottom of the page.
You may now add folder, sync media files be it pictures, images and videos from the mobile application. Owncloud lets you add new user, and sync calendar, contacts, Media files, etc.
It also has a built in MP3 Player, PDF Viewer, Document Viewer, and a lot many which is worth a try and explore. So what are you waiting for? Become a proud owner of private cloud storage, give it a try!
