<p>The safest, most reliable way to transfer from XP to Win7 is to install Pegasus Mail on the Win7 machine, configure it as needed using the XP install for reference, then restore messages, folders & addressbooks from the mailbox directories on the XP machine to the mailbox directories on the Win7 machine.</p>Worthy of note: <ul><li>Pegasus Mail can not be installed anywhere inside of \Program Files (default is C:\PMAIL)  </li><li>Care must be taken not overwrite any configuration files when transferring data from the XP machine.</li></ul> There is a guide to Pegasus Mail filenames and file-extensions that is useful in determining which files you may want to transfer over.  It is located here:   http://www.vandenbogaerde.net/pegasusmail/pf_pmfiles.html There is no guide for this process because there are too many variables.  A benefit of Pegasus Mail is its flexibility but in this case that flexibility is also a curse.  We are here to answer any specific questions you may have about whether a file is safe to copy from a previous installation. To answer your specific question about the \Mail directory, that directory contains the Pegasus Mail user list and the mailbox directories.  It can not be copied intact because most of the Pegasus Mail configuration files reside inside of the mailbox directories and are installation specific.  Many folks have had success with a wholesale copy but there are caveats to making this work and no guaranties that it won't introduce problems that are difficult to troubleshoot.

<p>After numerous errors and false starts I managed to get PMail more or less transferred to Win 7. I have experienced some issues with the file folders that were archived. Apart from some file folders names being rearranged  (I can live with that) there are now two light green folders that are a mystery (<b>:51-52 828 Add Process ExspinDN.exe proces -24916.23</b>). These appears twice, sometimes 3x. If I try to delete any one, Pmail crashes. I have checked every PMail directory and cannot find any files that look suspicious or problematic. Any help or suggestions will be most appreciated. </p><p> </p><p>When I tried copying over my mail files previously, Pmail repeatedly asked me for a username which I don't use as I am the only user. </p>

You are probably best advised to revisit the transfer process and perhaps redo it. There are numerous posts on the subject and you should read some of those before going ahead, particularly if you have a non default installation.

Thanks for your reply. I did read those posts before attempting the move. Unfortunately the instructions remain vague when you are asked whether to replace or keep a file in the Mail folder.These appear to be non-mail files. Do you replace them or keep them?
