Hi,
It appears to be that all emails are stored inside a single file with no file extension, and a second file seems to be an index file for all the email.
Due to time limitations on the current case and the fact that it is Chinese New Year (we are based in Hong Kong) we are exporting email from Foxmail in .eml format for all custodians. This is the only option for export.
Not ideal but there seems to be no other option, we cannot find other software, tools, scripts that will convert this.
A fix would be magic!
Alan
