Jukka Zitting resolved TIKA-1260.
---------------------------------

       Resolution: Not A Problem
    Fix Version/s:     (was: 1.5)

What you're seeing is the result of using the file name as a hint of the type of the file. If the file name ends in {{.txt}} or some similar suffix, it probably should be treated as a text file, even if it doesn't contain anything. Only when no such hints are available will Tika fall back to {{application/octet-stream}}. See:

{code}
$ touch empty.txt
$ java -jar tika-app-1.5.jar --detect empty.txt
text/plain
$ java -jar tika-app-1.5.jar --detect < empty.txt
application/octet-stream
{code}

> Running Tika with the -d (detection) option, any zero-byte files are identified as "text/plain". I'm wondering if this is the intended behavior? I know the Unix File tool reports "inode/x-empty" in such cases. Perhaps Tika should do this as well?
