File Map and Drive Map

The File Map shows the positions and sizes of the file areas. A file map provides a graphic representation of the Area Pane and appears for existing files only (or after the first Save command).

       File Map

Area is a block of data created as a result of editing operation. For example, a file just opened consists of a single area of original data. Changing a byte in the middle of the file converts the layout to three areas  original data before the changed byte, one byte long modified area, and an original data area from the changed byte to the end of the file.

Tip Point an area with the mouse cursor to open the area info window; right-click the area to open the area menu.

Legend

There are five types of data areas:

  • The original data are shown in green. Neither the data themselves, nor their position have been changed.
  • Blue is the color of data shifted up (to the sky). The data are unchanged, but deleting some bytes caused the area move in the direction of the beginning of the file.
  • Light brown is the color of an area shifted down (to the ground). The area contains the original data, but the position of the area has been changed as a result of some insertion operation.
  • Modified or inserted data blocks are shown in red.
  • Light gray is the color of a zero area, that is either sparse zero block, or a block inserted with the Insert Zeros command.
Tip You can change the assigned colors by using the Tools / Layout and Colors command

Drive Map

Drive Map is basically the same thing as File Map (both are actually stream maps). However drive maps are much less useful because in case of drives we usually have huge streams and tiny modification areas. Drive maps seldom provide useful information so they are turned off by default.
