Dell Inspiron 13 laptop Windows 10 256 GB SSD Thunderbird 102.12.0 (32bit) Over the last few months I've noticed the SSD becoming nearly full without apparent reason and traced this down to: AppData/Roaming/Thunderbird/Profiles/f9wj1lzh.default/ImapMail/ imap.mail.yahoo-3.com which consumes 111GB. There are 162 nstmp files which account for 73GB of this and one INBOX file of 39GB. The INBOX I can believe as reasonable but I've formed the impression from reading other threads in the help pages that the nstmp files can be erased. Perhaps not the most recent? Is this the case? I have a total of three rocketmail (yahoo) email accounts. Jim
