Hi, @김성찬,

From your picture, I suppose that the following regex S/R should work !

SEARCH (?-s)^.{56}

REPLACE Leave EMPTY

Notes :

First the in-line modifier (?-s) means that the regex dot char ( . ) matches a single standard character only and not the line-breaks \r and/or \n
Then, from beginning of line ( ^ ), it matches the first 56 characters of any line… and deletes them, as the replacement zone is EMPTY

@김성찬
just curious, do you know that you can press and hold
SHIFT+ALT and use the mouse to select a rectangle, which then
can be easily deleted?

@Ekopalypse
i know SHIFT+ALT and use the mouse to select a rectangle and delete it
but select a rectangle sentence is over 400,000 line
So i needed another way

@김성찬

even in this case it would be easy to do it.

Click on the starting point
scroll down to the end
press and hold SHIFT+ALT and click with the mouse to the end point.

Note, I don’t want you to refuse using regexes,
just want to make sure that some actions can be done with using it,
especially when it comes to rectangular selections, easily.

Hello, @김성찬 and All,

An other and easy solution is to use the Begin/End Select feature !

1 Left click at the very beginning of the first line 0000 90 9F 33 .. .. .., to move the caret to this location
2 Select the option Edit > Begin/End Select
3 Use the Ctrl + End shortcut to get the very end of your hexadecimal dump text
4 Press and hold down the ALT key and left click after the 16th hexadecimal byte of the last line
5 Select, again, the option Edit > Begin/End Select

=> After a while, needed to process 400,000 lines about, as you said, you should notice this big rectangular selection !

6 Simply, press the Delete key

Voila :-))

Best Regards,

P.S. :

If you forget to hold down the ALT key, at step 4 of the method above, you, obviously, get a normal selection of all your text !
