Extracting jar file received as an e-mail attachment

[Giovanni Guglielmo Jr.]

Does anyone ever have a problem extracting a jar file that was received an
e-mail attachment?

I created the archive using:

jar -cf myFile.jar myDirectory

and extracted it with no problems using:

jar -xf myFile.jar.

But if, before extraction, I email myFile.jar to myself as an attachment
using MSOutlook, the command above extracts only a few of the files.

The jar file is less than 1MB (856,670 bytes) and its size does not change
after e-mailing, so it does not seem that data was lost during
transmission.

Any idea of what could be wrong?

It is no thing to do with Outlook. I do it quite often (1-2Mbs).
Something wrong with quality of your network or post server. Files become
corrupted, I think.
