Note: sector edit is of high risk, thus do not try this function if you do not have a good command of related knowledge.
This function consists of five parts:
From left to right: save, copy, paste, undo, find hex values, find text, go to offset, go to sector, last sector, next sector, go to first sector, go to last sector, last cursor, next cursor, interpret as partition start, endian convert, calculator and directory browser.
This part shows files and folders of the partition whose sectors are being edited. The place of currently selected item can be reached by using context menu (e.g. beginning sector of file, file record, index, parent directory record, directory entry and beginning sector of parent directory). Double click the folder to visit its files and click the mark ".." to return to parent directory.
This area interprets current cursor. When legal and valid data is entered the edit box, the interpreter will automatically convert it to corresponding hex value and write it to area ④, which saves manually conversion. Here are the types it can interpret:
This area divides into three parts: offset area, hex edit area and text edit area. Mouse dragging is supported. Changed part will turn red, otherwise keeps black.
This area shows the current sector and sector count, offset, interpretation of current cursor, range of selected blocks and block size. Also it supports copying through right mouse button (hex and decimal).
