When you edit existing interpretations text, if you make the new text longer than the original text, then the new text will be added to the end of the file, thus making it larger. The space occupied by the original text is no longer needed, but still occupies some space in the file. The space that is wasted due to this process is negligibly small if you only edit a small number of interpretations, but if you make a large number of alterations, then you may wish to recover the wasted space. This is possible by compacting the file.
>> To compact the current interpretations file
•Select Compact from the File menu,
You will be asked to confirm whether you wish to proceed, and if you click OK then the entire interpretations file will be rewritten to the disk using the minimum space possible. When the process is finished, you will see a message indicating how much space was saved.
