MOVEDIR Method (FileSystem)

Moves a directory and subdirectories to a specified location, optionally showing a progress information and allowing an Undo operation.

SuccessFlag = Exec_Method( "FILESYSTEM",  

                              "MOVEDIR",     

                              DirFrom,       

                              DirTo,         

                              MoveDirOptions )
 
NameRequiredDescription
DirFromYesFully qualified path of the directory to move.
DirToYesFully qualified path of the location to move the directory to. Wildcard characters are not supported in this argument.
MoveDirOptionsNoContains an @Fm-delimited dynamic array of options that control the behavior of the move operation:



<1> Allow undo

<2> Allow UI

<3> Parent window ID

<4> Progress dialog title

<5> Allow confirmations

TRUE$ if the move was performed successfully, or FALSE$ if an error occurred. If the case of the latter event the FILEOPRESULT property may be used to obtain more details regarding the failure.

The MoveDirOptions argument is composed of five fields which control the behavior of the move operation – each field is described fully below:

FieldNameDescription
<1>Allow undoIf TRUE$ then save Undo information. Defaults to FALSE$.
<2>Allow UIIf TRUE$ then allow any appropriate dialogs to be displayed such as progress and error information. Defaults to FALSE$.
<3>Parent window IDSpecifies the name of a WINDOW object to use as the parent for any dialogs displayed during the move operation.
<4>Progress dialog titleText to display in the progress dialog during the move operation.
<5>Allow confirmationsIf TRUE$ then allow the user to respond to any confirmation dialogs presented during the move operation. Defaults to FALSE$.

The MOVEDIR method is basically a wrapper around the SHFileOperation Windows API function, so it is worth examining at the documentation for this on the MSDN website to get a better idea of the capabilities of this method.

You should use fully qualified path names with this method. Using it with relative path names is not thread safe.

Equated constants for use with the MOVEDIR method can be found in the PS_FILESYSTEM_EQUATES insert record.

 
// Use the FILESYSTEM MOVEDIR method to move an entire folder and it's

   // contents to another location, showing any progress information, but not

   // allowing the user to override any conflicts.

   

   $Insert PS_FileSystem_Equates

   $Insert Logical

   

   DirFrom     = "c:\my_data\aug_2017"

   DirTo       = "c:\backup\backup_data"

   

   MoveOptions = ""  

   MoveOptions<PS_MVD_ALLOWUNDO$>     = TRUE$  ; // Save Undo info

   MoveOptions<PS_MVD_ALLOWUI$>       = TRUE$  ; // Show dialogs

   MoveOptions<PS_MVD_PARENTWINDOW$>  = @Window

   MoveOptions<PS_MVD_PROGRESSTITLE$> = "Moving data to backup folder"

   MoveOptions<PS_MVD_ALLOWCONFIRM$>  = FALSE$

   

   If Exec_Method( "FILESYSTEM", "MOVEDIR", DirFrom, DirTo, MoveOptions ) Then

      // Moved OK - data is now in:

      //

      //      "c:\backup\backup_data\aug_2017"

   End Else

      ErrorInfo = Get_Property( "FILESYSTEM", "FILEOPRESULT" )

      

      ErrorCode = ErrorInfo<PS_FOR_ERRORCODE$>

      ErrorText = ErrorInfo<PS_FOR_ERRORTEXT$>

      

      // Handle Error  ....

   End
