Abstract
Disclosed herein are methods, systems, and computer program products for managing data within a file system. In embodiments, the method includes determining the location of data within a file to be modified, modifying the data within the file, and adjusting a pointer to point to the data block containing the modified data. The data within a file may be modified by deleting data from the file or inserting new data into the file. New data may be inserted into a file by writing the data into new data blocks and then adjusting the pointers to point to the location of the new data blocks. An example method may also include determining whether data blocks are incomplete blocks and identifying the incomplete blocks by negating the value of the pointers to those blocks.
