# How to: Copy a Directory to Another Directory in Visual Basic

Use the CopyDirectory method to copy a directory to another directory. This method copies the contents of the directory as well as the directory itself. If the target directory does not exist, it will be created. If a directory with the same name exists in the target location and overwrite is set to False, the contents of the two directories will be merged. You can specify a new name for the directory during the operation.

When copying files within a directory, exceptions may be thrown that are caused by specific file, such as a file existing during a merge while overwrite is set to False. When such exceptions are thrown, they are consolidated into a single exception, whose Data property holds entries in which the file or directory path is the key and the specific exception message is contained in the corresponding value.
