Abstract
Accessing a file on a sequentially accessed storage device such as a magnetic tape often involves bypassing valid files and gaps between valid files. Presently taught is a method of copying valid files being bypassed to a second sequentially accessed storage device while not copying the gaps. When a read target file is reached, the read target file is read. During a write to a file writing position, valid files are copied to the second sequentially accessed storage device until the file writing position is reached and the file is written at the end of the valid files on the second sequentially accessed storage device.
