Which Is Better: Manual Conversion or Email Converter Software?

[Client Thomaswilson081]

I need to convert a large number of email files from one format to another for backup and migration purposes. I am confused between using a manual conversion method and professional email converter software. Manual methods seem free, but I have heard they are time-consuming and risky for large amounts of data. On the other hand, email converter software claims to be faster and more accurate, but involves cost. In situations like bulk conversion, maintaining folder structure, and avoiding data loss, which option is better and why? Please share your experience and suggest the most reliable solution.
