I wrote this tool to convert the address book of Evolution (which uses VCard) in a suitable format for Thunderbird (which uses LDIF). This two formats are not identically and also do not store the same things in the same way. Therefore this tool has to make some simplifications, assumptions and suggestions.
I designed the tool so, that both ways will work. Maybe it will work for other situations too. If there are suggestions for improvements, please send me an mail to joerg@toolcase.org and attach the files you used (they will be used carefully of course).
The tool will detect the content by its syntax and not by the file extension. The content of the file will be converted to the other syntax.
Outlook can only import one contact per VCard-file. A workaround ist to use Windows Contact inbetween. See here for more details. A zip support for this tool is planned.
VCard is a standard format for exchanging addresses between different software and hardware. Syntax definition: VCard 2.1
LDIF (Lightweight Directory Interchange Format) is a ASCII-format for exchange of small data amount, as addresses are.
