finding out the file properties

i want to find out the properties of file(exe file)like version number,size on disk and etc.can any body help me in this regard..
thanks in advance...

Java concentrates all sorts of file related methods in the java.io.File class. That is where you should start looking.

For details that File can't provide you (like version number) you will probably have to go to operating system specific methods.

.i couldn't found any methods in the standard api

There is a very good reason for that - the designers intend Java to run on as many operating systems as possible, therefore the standard library only contains functions that can reasonably be expected to work everywhere.

You are asking about file properties that are NOT industry standards or portable across multiple operating systems. You are going to have to dig into the details of each type of file format on a case by case basis.

This web site has collected many of the common formats - if this was my problem I would start my search there.
