get drive type

[Stefan Poehn]

Hi

is there any possibility to find out the drive type of a given path ("C:",
"D:", etc.)? I want to search through a complete hard disk drive to find a
file with a given name, but not search through a cd rom drive, etc.

Thanks
Stefan

Not in a platform-independant way. On Linux, you'd have to parse /etc/fstab;
on Windows you'll probably have to use system calls via JNI.

There must be a way cuz I've run programs on pc that show this info. You
might
have to call some system functions.

Do these programs start without using a .dll or .so-File? If it is a Unix
program, does it run without using /etc/fstab?

Ok, I looked at one of the programs, but all I have is the .exe file.
I searched for ascii strings in the .exe and found "KERNEL32.dll"
Then I used "dependency walker" to look at Kernel32.dll and I find two
functions
GetDriveTypeA and
GetDriveTypeW which I assume you can use to get the info you need.
Look at MSDN on the web (somewhere at microsoft.com) for details.
Then you can write a little c/c++ program that calls GetDriveType[A|W].
Then you can use the example at sun.com to call your program from java.

Hmm, this can only be JNI... I didnt want to use it, but unfortunately it
seems to be the only way to get the drive type (on windows).

Remember, I did not use these functions myself so there is no guarantee that
they will do what you want. Yoda says:
