ABSTRACT:
Systems and methods for changing items of a computer file, such as an archive file, can include an application programmed to create a file including a first item and a second item, the application storing the file on a storage medium. Systems can also include an input/output module associated with the application, the input/output module retiring the first item upon a change to the first item resulting in an increase or a decrease in a size of the first item. Upon retiring the first item, the input/output module can write a third item at an end of the file, the third item including the change to the first item. Methods can include retiring the first item upon a change to the first item, and writing a third item after the second item, the third item including the change to the first item.
