Hi, Im new here (But not to FreeBASIC), and I was wondering if anybody knew how to get the label and Free/total disk space from a given drive? and possibly the model name?

Thanks in advance.

Just use shell to access the command.com
Then use simple OS command line commands and save the output; just redirect it to a text file.

For example, to get the name of the harddrive, use the Volume command and pipe it to a text file (then read the text file later).

Code:
SHELL "vol > hdd_labl.txt"

That will shell out to the command prompt run the "vol" command and send the results to a newly created file named hdd_labl.txt which you can open and read later.

For disk size the directory command (dir) has a bunch of options.
the last two lines always output, are the the number of files in the current directory (folder) and the free disk space.

The output will look something like this:

Code:
 Volume in drive C has no label.
 Volume Serial Number is 686B-F0F2

 Directory of C:\

08/06/2009  04:30 PM    <DIR>          Temp
08/10/2009  07:48 AM    <DIR>          WINDOWS
               1 File(s)      1,892,240 bytes
               8 Dir(s)  35,276,324,864 bytes free
              29 Dir(s)  35,276,324,864 bytes free


Now good practice is to use specific file extensions for easier recognition by others - so if you forget to 'cleanup' they might know what the file is.
Suggestions:
TXT (text)
LST (list)
TMP (temp)
$$$ (string-temp)
$ (string temp)
QB (qbasic)

Another best practice would be to just "kill" the file after you are done with it, using the BASIC KILL command.

Hope this helps.
