[JAVA] Automatically transfer animations for each title and store them in a folder

Preface

Since the draft is full, I will post it for the time being The credibility of the content may be a little because of what I did in the past. But it's a waste to erase it, so I posted it.

Main subject

After recording with chinachu, I downloaded it to Windows and encoded it to mp4. However, as the number of files increased, I wanted to organize them.

What to do with this

1. Extract all mp4s in the specified folder ** ← bat file **
2. Extract text before white space in file name ** ← java ** from here
3. Search for the same folder as the text extracted in 2.
4. Create if the same folder does not exist
5. Move the file to the corresponding folder

code

animeSelection.bat

animeSelection.bat

@echo off

#Mp4 in the corresponding folder mp4 FileName.Store in txt
dir C:\ Users \ izumi \ Videos \ Anime \*.mp4 /a-d /b > mp4FileName.txt

# mp4FileName.Take txt line by line and pass it to java
for /f %%a in (mp4FileName.txt) do ( ^
  java animeSelection.animeBatch %%a
  timeout 3
)

			System.out.println("The corresponding character cannot be found.");

			System.out.println("The end position is" + i + "is.");

			Path tergetPath = Paths.get(dir + "/" + title + "/" + filename);
			System.out.println(sourcePath + "To" + tergetPath + "Go to.");
			Files.move(sourcePath, tergetPath);
