I was revising because I don't like forget the thread.

source=Source.txt
target=Target.txt

FileRead,lines,%source%
Loop,Parse,lines,`n                                ; Split by line break
{
  StringSplit,part_,A_LoopField,.                  ; Split by period
  If part_0<3                                      ; 1 part
    line:=A_LoopField
  Else
    StringReplace,line,A_LoopField,%part_1%.,      ; Remove part 1
  line=%line%                                      ; Remove trailing space
  string.=line "`n"                                ; Add line break

What can we do now ?
The post is opened but not working !!!!!!

Just as has happened before, it is quite difficult to understand what you are saying...

We had come to a working solution (post #18 in this thread, accepted by you in post #19), with only 1 question remaining:
- What should happen if a line in the file has only 1 period in it. Should that line be removed, or should it remain in the output?

Until this question is answered (I have asked 4 times before for an answer on this, this is the 5th and last time), any other questions (or solutions) here should be postponed, IMHO.

Phrase 1. Phrase 2. Phrase 3.
Phrase 4.
Phrase 5. Phrase 6. Phrase 7.

Phrase 2.
Phrase 3.
Phrase 4.
Phrase 6.
Phrase 7.

Phrase 2.
Phrase 3.
Phrase 6.
Phrase 7.

Perhaps an example would better explain the question?

Input text:

Code

Phrase 1. Phrase 2. Phrase 3.
Phrase 4.
Phrase 5. Phrase 6. Phrase 7.

Output Option 1 (Phrase 4 remains since it is the only Phrase in the line):

Code

Phrase 2.
Phrase 3.
Phrase 4.
Phrase 6.
Phrase 7.

Output Option 2 (Phrase 4 is removed because it is the first Phrase in the line):

Code

Phrase 2.
Phrase 3.
Phrase 6.
Phrase 7.

Which is the preferred output option, 1 or 2?
