using internal unpacker to open file with custom extensions

[ggiunta]

I'm pretty sure this is answered somewhere else in the forum, but I could not find it, so...

I have files ending in .ezpkg on my disk, which are really .tar.gz renamed.
I'd love tcmd to be able to open them natively without having to rename them.
Q: how to do it?

By using CTRL+Page Down as you can with all archives...
