input - source file
Parameters:
output - destination file
Parameters:
copyBuffer - buffer used for copying the number of bytes copied
throws:
IOException - if an I/O error occurs (may result in partially done work)

| copyRec | | public static void copyRec(File source, File target) throws IOException(Code) | | Copies one directory or file to another. Existing files will be replaced.
Parameters:
source - directory or file to copy from
Parameters:
target - directory or file to copy to
throws:
IOException - if an I/O error occurs (may result in partially done work) |
| createFile | | public static boolean createFile(String path) throws IOException(Code) | | Creates a file specified by a path. All necessary directories will be created.
Parameters:
path - path of file to be created true if file has been created, false if the file already exists
throws:
IOException - If an I/O error occurred |
| deleteFile | | public static boolean deleteFile(String path)(Code) | | Deletes a file specified by a path.
Parameters:
path - path of file to be deleted true if file has been deleted, false otherwise |
| fileExists | | public static boolean fileExists(String path)(Code) | | Checks if a file specified by a path exits.
Parameters:
path - path of file to be checked true if file exists, false otherwise |
| moveRec | | public static void moveRec(File source, File target) throws IOException(Code) | | Moves one directory or file to another. Existing files will be replaced.
Parameters:
source - file to move from

IOException - if an I/O error occurs (may result in partially done work) |
| removeRec | | public static void removeRec(File toRemove)(Code) | | Removes a file. If the specified file is a directory all contained files will
be removed recursively as well.
Parameters:
toRemove - file to be removed |
