maildir->mbox conversion script review

[matej]

Hi,

I am writing a script to convert couple of thousand emails (in couple
of hundred folders) and before I will get to the hard part -- maintaing
structure folders and subfolders, and maintaing record of the status of
the message, I would like to be sure that I have at least maildir->mbox
conversion right. Could anybody comment on the below shown code please?
Thanks a lot

Matěj

Email can be stored in two different formats: Maildir and MBOX. While Maildir stores each email as a separate file in a directory, MBOX stores all emails in a single file. If you need to convert Maildir to MBOX, you can do it by using GainTools Maildir Converter Software to convert Maildir to MBOX files without losing any data. Because of its simple layout, the program is easy to use and doesn't require technical knowledge. The software supports Windows 11, 10, 8.1, 8, 7, Vista, XP, and earlier versions. You can learn more about the features of the program by downloading the free trial version.
