The British Colonial Raj followed a strict hierarchical structure in their offices for file movement. A file was moved from the lowest to the higher officials, from the peons to clerks, to babus, to the highest official, helping them to arrive at any decision on a certain issue, as the officials in each hierarchy put their comments and sent the files. As this process was not properly organized, gradually a better system evolved for commenting and noting the necessary changes to be done on a document. The left side of the documents was used for attaching chits or tags with comments/notes. Much later, Lord Whitehall understood the importance of following a methodology in filing and introduced a formal methodology of filing and that’s how the system of filing got its name. After Independence the system is still followed and considered as convenient.
