I can't get the first condition

Question about the task

Archived

Everything works fine in IntelliJ. I put in a directory and file on my own computer to test it. Everything works. But for some reason, the tests don't like how I renamed the file. But it accepts the renamed file and writes to it properly. I'm ready to pull my hair out on this one. Any thoughts?

1. The main method is passed two arguments as inputs.
The first argument is path, which is the path to the directory; the second is resultFileAbsolutePath, which is the name (full path) of an existing file that will store the result.
2. For each file in the path directory and in all of its subdirectories, do the following:
For each file whose size in bytes is NOT greater than 50, do the following:
2.1. Sort them by file name in ascending order. Don't include the path when sorting.
2.2. Rename resultFileAbsolutePath to "allFilesContent.txt" (use the FileUtils.renameFile method and FileUtils.isExist if necessary).
2.3. Sequentially write the contents of each file from step 2.1 to allFilesContent.txt. After the body of each file, write "\n".
All files have the TXT extension.
Use "/" as the path separator.

Requirements:

The file passed as the second argument to main must be renamed to allFilesContent.txt.
You need to create a stream to write to the renamed file.
The contents of every file that is 50 bytes or smaller must be written to the allFilesContent.txt file.
The output stream to the file must be closed.
Don't use static variables.

File out = new File(args[1]);
    File newOut = new File(out.getParent() + "\\allFilesContent.txt");

    if (FileUtils.isExist(newOut))
        FileUtils.deleteFile(newOut);

    FileUtils.renameFile(out, newOut);
