2 different formats have claimed .asice over the years, so two files with the same extension aren't necessarily the same kind of thing.

How to open a .asice file

  • The program that created it is by far the most reliable way to open it.
  • On Windows, use a hex viewer or the free TrID tool to identify what the file really is.
  • On Mac or Linux, running `file yourfile` in the terminal identifies most formats instantly.

The registry records this extension against BDOC, Associated Signature Container Extended (ASiC-E), so software from that family is the most likely match.

How to convert a .asice file

  • Identify the file first, then look for an export or Save As option in whatever program can read it.

MIME type

When a .asice file travels over the web, servers label it with this MIME type:

application/vnd.etsi.asic-e+zip
