Ok, i just found working solution how:
-> remove first and last line in one ore more files in notepad, just using this regex:
find: `[^\r\n][\r\n]+(.[\r\n]+)[^\r\n]+[\r\n]*’
change for: \1
Check regex and matches new line, it works really fine! :)
Then i just easly can add something in first line with this regex:
find what: (.*)
replace with: WHATEVERTEXT\r\n\1
Also check new line and regex. And the last one action to add something in the last one line of file:
find: (.*)
replace with: \1PUT HERE ANY TEXT
