fMoveFile (Function)

In french: fDéplaceFichier

Moves a file from one directory to another. The file can be renamed during the move.

Example

// Déplacement d'un fichier
Res is boolean = fMoveFile("D:\Exemple\Fen1.wdw", "C:\Temp\Fenêtre\Fen1.wdw")

Syntax

<Result> = fMoveFile(<Path of source file> , <New file path>)

<Result>: Boolean

True if the move was performed,
False otherwise. To get more details on the error, use ErrorInfo with the errMessage constant.

<Path of source file>: Character string

Name and full (or relative) path of the file to move (up to 260 characters). A UNC path can be used. Wildcard characters are not allowed.
This parameter can be in Ansi or Unicode format.
This parameter can correspond to a full path or a path relative to the current directory (returned by fCurrentDir). This parameter is case-sensitive.
Reminder: In Android, the file system is read-only on the device and on the emulator. An application can only write to its installation directory or one of its subdirectories, as well as to the external memory (SDCard).

<New file path>: Character string

New name and full (or relative) path of the file (up to 260 characters). A UNC path can be used. Wildcard characters are not allowed.
This parameter can be in Ansi or Unicode format.
This parameter can correspond to a full path or a path relative to the current directory (returned by fCurrentDir). This parameter is case-sensitive.
Reminder: In Android, the file system is read-only on the device and on the emulator. An application can only write to its installation directory or one of its subdirectories, as well as to the external memory (SDCard).

Remarks

Moving or renaming a file

If <Path of source file> and <New file path> contain the same file name but different access paths, fMoveFile moves the file.

If <Path of source file> and <New file path> contain different file names and different paths, fMoveFile moves and renames the file.

Remarks:

In Windows, fMoveFile is equivalent to fRename.
In Android, a file stored on the external memory (SDCard) cannot be moved to the internal memory of the device and vice versa.

Handling errors

fMoveFile throws an error in the following cases:

the file to move does not exist,
the file to move is locked,
the path of the file to move is invalid,
<New file path> or <Path of source file> is an empty string,
the new file already exists.

Operating mode in Windows Vista (and later)

If this function does not work properly in Windows Vista (and later), check whether the file or directory used is not in one of the system directories (Windows directory or "Program Files" directory).

In Windows Vista (and later), with the UAC mechanism (User Account Control) enabled, you must have administrator privileges to handle and/or modify the files or directories in system directories (Windows directory or "Program Files" directory).

Programming tip: If you need to manipulate / modify files or directories, without needing administrator privileges, it is advisable:

avoid writing to the Windows directory or to the "Program Files" directory,
use the system directory of the application (returned by SysDir with the srAppDataCommun constant, for example).

Remark: Under Windows Vista and higher, the virtualization mechanism makes applications "Vista-compatible".. If the file is created in a system directory without having sufficient rights, this file will actually be created in another directory (C:\Users\<LOGIN>AppData\Local\VirtualStore\Windows\). In this case, the file cannot be shared between several applications.
