Get Filename from Byte Array

Question

We can extract the mimetype from byte array, e.g., by using Apache Tika.

Is it possible to get Filename from Byte Array.

@Joey Honestly I haven't tried any thing. I searched Google but didn't find a way to solve it. — Tapas Bose

How did you get the byte array? Only that makes all the difference! — Gagravarr

No. You can take a guess at a mimetype from the content data itself, but the filename is not in there.

The header field that you may be looking for is called Content-Disposition. If you're downloading an attachment, then there may be a file name in that field:

Content-Disposition: attachment;filename=abc.txt

But there's no guarantee that you'll have such a file name available. Also, this may only apply to HTTP and E-Mail content. From your question, it's not clear where your data's origin is...
