Retrieve deleted email addresses in Foxmail

I searched for emails from several friends in Foxmail and unfortunately found that my emails have been deleted. These mailboxes are especially important to me, so I tried my best to find them.

When writing an email, input the first letter of an email address in the "recipient" address, and Foxmail can automatically complete the email address, so try to enter a few letters, and the result does not reach the goal, then I thought again that since Foxmail has the "auto-complete mailbox" function, it means that these email addresses have been recorded in a certain file of Foxmail. After searching, I found the Foxmail under the Foxmail installation directory. the adc file is found.

The Foxmail. adc file records all input email addresses. When you enter an email address, Foxmail automatically compares it with the recorded address. If the previous letter is the same, it is automatically completed. Open the Foxmail. adc file and retrieve the deleted email easily.
