Remarks

Managing errors

fCopyFile generates an error in the following cases:

the file to copy does not exist,
the file to copy is locked,
is invalid,
<Path of copied file> is an empty string,
<Path of file to copy> and <Path of copied file> are identical.

Operating mode in Windows Vista (and later)

If this function does not operate 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).

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

Programming tip: To handle and/or modify the files or directories without administrator privileges, you should:

avoid writing into the Windows directory or into the "Program Files" directory,
use the system directory corresponding to the application (returned by SysDir associated with the srCommonAppData constant).

Creating directories during the copy

If one of the directories of the destination path does not exist, it is automatically created.
If the source file corresponds to all the files found in a directory (for example, C:\Temp\*.*), the frRecursive constant must be used to create the subdirectories in the destination (and to copy their content).

Remark: To copy directories, you also have the ability to use fCopyDir.

Equivalence

The operating mode of fCopyFile is equivalent to the operating mode of ceCopyFile.

The only difference is:

fCopyFile handles the files found on the Pocket PC from a WINDEV Mobile application.
ceCopyFile handles the files found on the Pocket PC from a WINDEV application.
