Although the Wine configuration program allows me to point to ext4 partitions, there is no indications that they will be able to be read. I do have that entry in operaprefs.ini as:

Mail Root Directory=K:\mnt\GENERAL\MAIL

where the "GENERAL" partition is an ext4

Will keep trying and let you know what happens.

I am using the 1044 version of Opera Mail. Although the Wine configuration program allows me to point to ext4 partitions, there is no indication that they will be able to be read. Will keep trying and let you know what happens.

Years ago using Opera Mail within the browser (now 12.16) I set up my mail accounts and omailbase.dat on a separate partition under the assumption that for any new version of Opera Mail I would simply have to redirect it to that partition and all my accounts and thousands of e-mails would be available.

Now however, when I try that with Opera Mail 1.0 I get a "failure to open omailbase.dat" message. It appears that somewhere between Opera 12.16 and Opera Mail 1.0 some or all of the basic mail files got revamped and are no longer compatible. I run Linux and am using Opera Mail 1.0 under Wine; I have easily entered the redirect address; however it is to an ext4 partition so I will next try moving the mail files to a NTFS partition.

Can anyone confirm an incompatibility between the mail files in Opera 12.16 and Opera Mail 1.0? Or must I go on banging my head against the wall?
