[prabhug1987]

Hi

I am trying to find the window default installation path for installing the software. help me

thanks in advance

There is no direct way to find the system folder using Java. However with a proper combination of several system properties it could be done.

[Eranga]

For an example, following statement always return the system drive in windows.

System.getProperty("user.home").charAt(0)

And there are many other ways to do that.

thanks Eranga,

it shows user directory as c. But i want to find the find path where the software is going to installed. for example java will be installed in c:\program files\java.

[Eranga]

Do you want to find the specifically any application installed path or the common installation path?

The thing is this, in most of the installation you can define the custom folder paths, like in D: and so on. For example JDK could install in C: drive.

I've got half a dozen JDKs installed on my D: drive on this machine, in a jdks folder.

I'm not sure there is a "common installation path", is there? At least not in the system properties.

[Eranga]

In System Properties you cannot find a such. But as I said you can manipulate it in many ways,

It's SystemDirve:\Program Files

[Tolls]

Except on my machine which has two.
ProgramFiles and Program Files (x86).

[Eranga]

Yes, it's correct. In my PC I've three systems partitions. But the point is, there is only one system drives, unless you don't have Windows installations.

But there is only one user root, in a single OS installation. So that user.home always have one value.

Say I've XP in drive c, it'll returns C:\Document & Settings\Eranga if I'm log into XP. Say Win7 in drive D: then the return is D:\Document & Settings\Eranga

[Tolls]

Oh yes, user.home is easy.
At least on Windows and *nix-based, not had to use anything else in years.

But "common installation path" is a nonsense, even on Windows.

I agreed with you. Specially with MSI packaging it's a killer.
