RenameFile

Rename a file.

Declaration

Source position: filutilh.inc line 232

function RenameFile(

  const OldName: UnicodeString;

  const NewName: UnicodeString

):Boolean;

function RenameFile(

  const OldName: RawByteString;

  const NewName: RawByteString

):Boolean;

Description

RenameFile renames a file from OldName to NewName. The function returns True if successful, False otherwise. For safety, the new name must be a full path specification, including the directory, otherwise it will be assumed to be a filename relative to the current working directory. Remark: The implementation of RenameFile relies on the underlying OS's support for renaming/moving a file. Whether or not a file can be renamed across disks or partitions depends entirely on the OS. On unix-like OS-es, the rename function will fail when used across partitions. On Windows, it will work.

Errors

On Error, False is returned.
