# FileCopyDir

Copies a folder along with all its sub-folders and files (similar to xcopy).

    FileCopyDir, Source, Dest [, Flag]

### Parameters

Source | Name of the source directory (with no trailing backslash), which is assumed to be in %A_WorkingDir% if an absolute path isn't specified. For example: C:\My Folder
Dest | Name of the destination directory (with no trailing baskslash), which is assumed to be in %A_WorkingDir% if an absolute path isn't specified. For example: C:\Copy of My Folder
Flag | (optional) this flag determines whether to overwrite files if they already exist: 0 (default): Do not overwrite existing files. The operation will fail and have no effect if Dest already exists as a file or directory. 1: Overwrite existing files. However, any files or subfolders inside Dest that do not have a counterpart in Source will not be deleted. This parameter can be an expression, even one that evalutes to true or false (since true and false are stored internally as 1 and 0).

### ErrorLevel

[v1.1.04+] This command is able to throw an exception on failure. For more information, see Runtime Errors.

ErrorLevel is set to 1 if there was a problem or 0 otherwise. However, if the source directory contains any saved webpages consisting of a PageName.htm file and a corresponding directory named PageName_files, an error may be indicated even when the copy is successful.

### Remarks

If the destination directory structure doesn't exist it will be created if possible.

Since the operation will recursively copy a folder along with all its subfolders and files, the result of copying a folder to a destination somewhere inside itself is undefined. To work around this, first copy it to a destination outside itself, then use FileMoveDir to move that copy to the desired location.

FileCopyDir copies a single folder. To instead copy the contents of a folder (all its files and subfolders), see the examples section of FileCopy.
