The method outlined below is a tried and true one that works quite easily.
In your case, since you have 4 files, just modify it to include archiv1,
archiv2, archiv3, and archiv4 for the DBX files in question. The
information is quoted from the website: www.oehelp.com

quote
"To backup and restore a single OE5 or 6 mail folder, save the appropriate
dbx file. To restore, create a new folder in OE5 or 6 (call it archiv1, for
example) and access it once. Then close OE and find archiv1.dbx and delete
it. Make a copy of the folder you want to restore and rename it to
archiv1.dbx. Then copy that file into the directory where the previous file
was deleted. Open OE and the messages you wanted to restore will be
accessible via opening that archiv1 folder."

Is it possible to merge dbx files into one identity?

I have transferred my emails from MN to FL for 4 years now, but I keep
forgetting to record my identity, and have used several different ones. As
a result, I have at least 4 dbx files holding emails, some of which I
would like to keep and consolidate with my present identity. In this way,
I will delete the other identities to get rid of this confusion.
