HPP-CK Improvement: Overwrite confirmation

[compsystems]

Hi, I had a backup of a file in a different folder, accidentally I dragged this file to the HPP-CK that previously exists, HPP-CK should display a replacement confirmation pop-up window, currently rewrites without confirmation.
Files with extension (1) or (2) They become [b]unusable. /b] if another file calls internal functions of the same,

I do not know what solution there could be, outside of what I propose in
http://www.hpmuseum.org/forum/thread-8025.html
When two users create a file with the same name

With a new INTERNAL CMD (KEYWORD) HPP-CK would no longer have to replace, else added an extension to differentiate n files with the same name

file1: linearAlgebra.hpprgm

PHP Code:

#INTERNAL vectors
EXPORT main()
...
END; 


vectors.main() // exe main of vectors

This would not affect old programs, if the compiler can not find the keyword
INTERNAL, takes the name of the file

file: linearAlgebra.hpprgm

PHP Code:

EXPORT main()
...
END; 


linearAlgebra.main // exe main of linearAlgebra


/////////


Another user could create a file of the same name and HPP-CK would differentiate it by the internal name

file1: linearAlgebra.hpprgm

PHP Code:

#INTERNAL vectors
EXPORT main()
...
END; 


file2: linearAlgebra.hpprgm

PHP Code:

#INTERNAL abcd
EXPORT main()
...
END;
