EF file extension

Question

How can I open Easy-firmware's EF file extension? The tool they provide is windows only and they will not provide a supposed password to open in Linux. They started this crap extension after I had paid for membership and now I can't access the files I've purchased. I say supposed password because their "tool" is for opening their own EF firmware files with EF.ext without password. It's like they're hacking their own stuff or incapable of maintaining a password system. Help with an opening solution would be greatly appreciated. thanks

Linux does NOT have "file extensions offering type information", like Windows (remember the foo.pdf.exe bug?).

Linux filenames can contain any ASII character, except NUL and /, and, if they hint at a file's contents (foo.c), they do so only by convention.

Filenames with special characters in them require careful handling in scripts.

Handily, some Linux tools produce or accept lists of filenames with NUL (000) between filenames. Some are:

du - estimate file space usage
find - search for files in a directory hierarchy
grep, egrep, fgrep, rgrep - print lines matching a pattern
perl - Practical Extraction and Report Language
shuf - generate random permutations 
sort sort - sort lines of text files
uniq uniq - report or omit repeated lines
xargs - build and execute command lines from standard input
xz ,  unxz, xzcat, lzma, unlzma, lzcat - Compress or decompress .xz and .lzma files
modinfo - program to show information about a Linux Kernel module

Finally, try file foo.EF (if it says data, you're probably out of luck). Other tools that may let you look at the data in the file are strings foo.EF, and od -bc foo.EF.

You could also install wine (start with apt-cache search wine and go from there), and see if their tool runs under wine.
