Syntax:
+[int] sysinfo.drivefree(String drivename)+
Description:
+The drivefree method can be used to detect the space available for memory storage on a device.
Argument:
+drivename:
Specifies the name of a drive to be examined.
+ +Return value:
+If the drive exists, this method returns an integer value indicating the available space on the specified drive, measured in bytes.
+Example code:
+function checkDrivesInformation() {
+ var space = 0;
+ // get existing user's drives
+ var allDrives = sysinfo.drivelist;
+ var drives = allDrives.split(" ");
+ // read and print all drives’ name and information
+ for (var i=0; i<drives.length; i++) {
+ space = sysinfo.drivesize(drives[i]);
+ space /=1024; // convert from bytes to kB
+ alert("Total space of drive "+drives[i]+" ="+space+"kB";
+ space = sysinfo.drivefree(drives[i]);
+ space /=1024; // convert from bytes to kB
+ alert("Free space of drive "+drives[i]+" ="+space+"kB";
+ }
+ }
