Insert Zero Block
This command inserts a block of zeros at the specified position.
Depending in the current insertion mode, the Insert Zero Block
command either inserts or overwrites the existing data at the insert position.
The Insert Zero Block command works slightly differently from the
Insert Immediate Data command. While in most cases you can use either
command to insert a block of zero bytes, these commands works differently for
sparse files. Insert Zero Block inserts sparse zeros, whereas
Insert Immediate Data always inserts actual data occupying disk space.
File Map and
Area Pane recognize and
display blocks created with the Insert Zero Block command.
As in other dialogs, FlexHEX assumes the number is hexadecimal if it contains
hexadecimal digits A to F. Otherwise it is treated according to
the Dec/Hex selector.
