i am wondering regarding Java: is there a file extension separator?
like *.doc, the “.” being the question.
i know there is a line.separator. just would like my app to be portable so i need to know.
thank you.
The
.being a filename from file extension separator is an artifact of DOS and it’s 8.3 filename limitations. On Windows, MacOS X, Linus, etc that’s no longer that case..is just any other character (although a leading.on Linux/Unix filesystems indicates a hidden file).Windows systems still use the convention (even though you can create a filename with as many periods as you wish) as the extension is still used to file type and association. Linux/Unix/MacOS X tend to rely on magic numbers more than file extensions although there are conventions used there too (eg
.pl' for Perl files,.sh` for Shell scripts and so forth) but, unlike Windows, these are just conventions that have no OS meaning.So basically there is no concept of “file separator”. Not in a universal sense anyway.
