File Data Splitter 0.1.0
Author see https://github.com/password-checker/file_data_splitter
Split lines from a source file in folder and file structure.
For example: the line "415ab40ae9b7cc4e66d6769cb2c08106e8293b48" will saved in
the file "<OUTPUT_FOLDER>/415/ab.txt". The used part "415ab" is removed and the
remaining line is written "40ae9b7cc4e66d6769cb2c08106e8293b48".
Hint: The source lines should be sorted. If the file is sorted, each target
file is written only once and does not need to be opened again and again.
Hint: There is no different handling for upper and lower case. All letters have
to be in one case or the file system have to handle both cases.
Limits: The line length have to be at least <directory-length> + <file-length>.
In the example these are 5 signs. The splitting is done by signs, not by
graphemes!
