You should not remove that file. In general, don't remove random files that you have not created yourself.
It's the executable file for the [ utility. This utility is exactly the same as test but requires that the last operand is ].
See man [ and man test.
Example of use:
[ -n "hello" ] && echo '"hello" is a non-empty string'
You would also be able to use
/bin/[.exe -n "hello" ] && echo 'That works too'
(though I don't have access to Cygwin to try it, so I don't know if you need to specify the .exe suffix on the command or not)
Note that /bin/[.exe is the executable file for the external [ utility. This utility is very often also available as a built-in utility in your shell. If your shell is bash, then man bash (and help [) would document it.

This is ironically enough, hilarious. I did not know that was a legitimate executable. I thought it as a potential security risk through a regex related attack. Thank you very much for this information, it was thoroughly explained well,... formerly not, (now should be for others), provided through google/forum indexing.
