This is the second time happening with me. Last time I got suggestion from a friend on same forum to use Disk Usage Analyzer to check whats consuming too space. I found out that its Thunderbird.
Same thing happening again on daily basis it is consuming more that 4GB of space I have 100GB of total space and on this rate I'll be out of space in 1 week.
More than that When i send some email its takes much time in copying the space on local repository and Gmail account.
Maximum size of email which i send is 22 to 30KB which is just text.
