Method one, deletion binary recording operation generally use in the position of binary recording to be deleted fills word
Symbol covers this binary recording to be deleted.
In method one, if the position of binary recording to be deleted is at the end of binary file, namely
This binary recording is the last item binary recording in binary file, then this directly with filling word
The mode that symbol covers can realize deleting binary recording, if the position of binary recording to be deleted is not
End in binary file, then, owing to the length of each binary recording is not fixing, arise that
After binary recording to be deleted is filled character covering, first, this binary recording to be deleted is corresponding
Fill character limited length, possibly cannot be fully utilized, can only for this binary recording to be deleted with long
Degree or the shorter binary recording of length use, secondly, and the filling word that this binary recording to be deleted is corresponding
All there is effective binary recording in the front and back of symbol, when resolving this binary file, analysis program is not
Can determine that the length filled character, therefore, it is impossible to determine that the next-door neighbour afterwards that fills character fills character accurately
The starting position of effectively record, cause binary file to resolve unsuccessfully；
Further, binary recording to be deleted is deleted signal for directly using to fill character by Fig. 1 a～Fig. 1 b
Figure, the characterizing part same binary recording of identical filling pattern in figure, it is to be deleted that Fig. 1 a characterizes deletion
Two-stage system file before binary recording 101, Fig. 1 b characterizes directly to use and fills character to be deleted two
Binary file after system record 101 filling, it is seen then that the original position of binary recording 102 is difficult to quilt
The analysis program resolving binary file accurately determines, causes binary file to resolve unsuccessfully.
Further, in order to ensure binary file delete after binary recording can successfully resolved, existing
There is in technology the method that also proposed two: by the binary recording after binary recording to be deleted totally to reach
Dynamic, the position of record to be deleted is covered.
In method two, during binary recording is totally moved forward, need a plurality of instruction ability
Completing, every instruction can complete the movement of partial binary record, if performing partial binary note
After record, binary file place equipment generation abnormal conditions make the movement of binary recording the completeest
Become, then be likely to cause binary file to resolve unsuccessfully.
Further, Fig. 2 a～Fig. 2 b is that the mode using mobile binary recording is by binary recording to be deleted
Deleting schematic diagram, Fig. 2 a characterizes the binary file deleted before binary recording 201 to be deleted, Fig. 2 b
Characterize the binary file after using the mode of mobile binary recording to be moved by partial binary record.As
Shown in Fig. 2 a, the binary recording after binary recording 201 to be deleted is followed successively by binary recording 202
With binary recording 203, as shown in Figure 2 b, it is assumed that after moving binary recording 202, exception occurs,
So binary file has reformed into the binary file as shown in 2b, say, that binary recording 202
It is moved to the position of binary recording 201 to be deleted, and binary recording 202 after movement and not moving
Create the ending of the binary recording 202 before moving between dynamic binary recording 203, become
Redundant data 204, after the most processed, analysis program cannot parse redundant data 204, causes
Binary recording 203 cannot normally be read, and namely binary file resolves unsuccessfully.
