| Type | Topic | Plugin | Version | macOS | Windows | Linux | Console & Web | iOS |
| method | Files | MBS Util Plugin | 9.8 | Yes | Yes | Yes | Yes | No |
Example:
// Sample values in German:
// SnowLeopard/Programme/Dienstprogramme/Konsole
MsgBox SpecialFolder.Applications.Child("Utilities").Child("Console.app").DisplayPathMBS("/")
// SnowLeopard/Benutzer/cs/Schreibtisch
MsgBox SpecialFolder.Desktop.DisplayPathMBS("/")
// SnowLeopard ➜ Programme ➜ Dienstprogramme ➜ Konsole
MsgBox SpecialFolder.Applications.Child("Utilities").Child("Console.app").DisplayPathMBS(" ➜ ")
// SnowLeopard ➜ Benutzer ➜ cs ➜ Schreibtisch
MsgBox SpecialFolder.Desktop.DisplayPathMBS(" ➜ ")
folderitem.EjectVolumeMBS(force as boolean, byref dissenterPID as Integer) as Integer
Function:
This routine ejects the volume specified by folderitem.
Example:
Notes:
If the volume cannot be ejected the pid of the process which denied the unmount will be returned in the dissenter parameter. This routine returns after the eject is complete. Ejecting a volume will result in the unmounting of other volumes on the same device.
force: Specify true if you want the volume forcibly unmounted. Force unmounting a volume will very likely result in data loss since the volume will be ejected even if there are open files on it. This option should be reserved for situations such as the backing store for a volume is gone (so the data is lost regardless).
dissenterPID: Optionally, pid of the process which denied the unmount if the unmount is denied.
Returns a Mac OS error code. 0 means no error and -1 is a plugin error if the function can't be called. -47 is returned if the disc is in use.
PS: Seems like on my tests the pid is not set by Apple.

Example:
dim disk as FolderItem
dim c as Integer = VolumeCount-1
for i as Integer = 0 to c
dim v as FolderItem = volume(i)
if v.Name = "testvolume" then
disk = v
exit
end if
next
if disk = nil then
MsgBox "Please change the name in this code."
else
dim pid as Integer
dim e as Integer = disk.EjectVolumeMBS(false, pid)
if e=0 then
msgBox "Volume unmounted."
else
if pid=0 then
msgBox "Failed to unmount with error: "+str(e)
else
dim name as string
dim p as new ProcessMBS // from Util plugin
p.GetFirstProcess
do
if p.ProcessID = pid then
name = p.Name
end if
loop until not p.GetNextProcess
if len(name)>0 then
msgBox "Failed to unmount with error: "+str(e)
else
MsgBox "Failed to unmount."+EndOfLine+EndOfLine+"The application "+name+" is still using this volume."+EndOfLine+"Error: "+str(e)
end if
end if
end if
end if
If the volume cannot be ejected the pid of the process which denied the unmount will be returned in the dissenter parameter. This routine returns after the eject is complete. Ejecting a volume will result in the unmounting of other volumes on the same device.
force: Specify true if you want the volume forcibly unmounted. Force unmounting a volume will very likely result in data loss since the volume will be ejected even if there are open files on it. This option should be reserved for situations such as the backing store for a volume is gone (so the data is lost regardless).
dissenterPID: Optionally, pid of the process which denied the unmount if the unmount is denied.

FolderItem.FilesMBS as Folderitem()
Function:
Returns array of files in the given folder.
Example:
Notes:
Similar to item() function, but returns all files with one call.
| Type | Topic | Plugin | Version | macOS | Windows | Linux | Console & Web | iOS |
| method | Files | MBS Util Plugin | 12.0 | Yes | Yes | Yes | Yes | No |
Example:
dim folder as FolderItem = SpecialFolder.Desktop
dim files() as FolderItem = folder.FilesMBS
MsgBox str(UBound(files)+1)+" files"
Folderitem.FinderLabelMBS as Integer
Function:
Returns the color code for the file.
Example:
Notes:
The file label is a number between 0 and 7 to give the file a color.
Used in the Classic Finder for labels (and on Mac OS X for Finder replacement or Finder extending utilities)
On reading the value you can get negative values like -43 if the file is not found.
To know labels and colors, please use NSWorkspaceMBS.fileLabelColors and NSWorkspaceMBS.fileLabels methods.
(Read and Write computed property)

FolderItemToPathMBS(file as folderitem) as string
Function:
Returns a unix path for the given folderitem.
Notes:
Works only on Mac OS X.
This function is not very good, as Apple doesn't document for FSRefMakePath what path it returns, which encoding the path uses (maybe UTF8) and when it fails.
(e.g. it currently doesn't work for volumes)

Folderitem.GetFileAttributeMBS as Integer
Function:
Get the file attributes for the folderitem to the given value. Returns a negative if there is an error.
Notes:
Returns the flAttrib of a file. If you pass in a non-existing file or a folder, a negative error code is returned instead.
The flAttrib is a set of bits with the following meaning:
(See GetFileFlags for an example on how to check the bits)
On Mac OS X the information whether a file is open is not available.
