|

|
||||
Incremental loading technique allows a more fine-grained approach for loading files,
|
||||
which is especially beneficial when dealing with huge files
|
||||
(e.g. I want to load only item 26 and 72, not the whole file in one shot).
|
||||
|
||||
The only input is the file path, optionnal inputs are is the reading mode of the file and unload.
