roStorageInfo

This object is used to report storage device usage information.

Object Creation: The roStorageInfo object is created with a parameter that specifies the path of the storage device. The

path does not need to extend to the root of the storage device.

CreateObject("roStorageInfo", path As String)

Interfaces: ifStorageInfo

The ifStorageInfo interface provides the following:

Note: On some filesystems that have a portion of space reserved for the super-user, the following expression may not be

true: GetUsedInMegabytes + GetFreeInMegabytes == GetSizeInMegabytes

• GetFailureReason() As String: Yields additional useful information if a function return indicates an error.

• GetBytesPerBlock() As Integer: Returns the size of a native block on the filesystem used by the specified

storage device.

• GetSizeInMegabytes() As Integer: Returns the total size (in mebibytes) of the storage device.

• GetUsedInMegabytes() As Integer: Returns the amount (in mebibytes) of space currently used on the

storage device.

Note: This amount includes the size of the pool because this class does not integrate pools into its calculations.

• GetFreeInMegabytes() As Integer: Returns the available space (in mebibytes) on the storage device.

• GetFileSystemType() As String: Returns a string describing the type of filesystem used on the specified

storage. Potential values are fat12, fat16, fat32, ext3, ntfs, hfs, Hfsplus.

• GetStorageCardInfo() As Object: Returns an associative array containing details of the storage device

hardware (a memory card, for example). For SD cards, the returned data may include the following:

1 2 ... 163 164 165 166 167 168 169 170 171 172 173 ... 340 341
