As posted in other SO questions about file operation atomicity, Win32 was simply not designed for transactions. Still I wonder whether file deletion could be non-atomic. After all, it is either get deleted or not. Or can a file remain in any other intermediate state on NTFS file system caused by a system crash or something else during deletion?

files. deleteifexists(Path p) method defined in Files package: This method deletes a file if it exists. It also deletes a directory mentioned in the path only if the directory is empty.
In Java, we can use the NIO Files. delete(Path) and Files. deleteIfExists(Path) to delete a file.
You can't delete a file when running JavaScript from the browser, but you can do it when running JavaScript from a server environment like NodeJS. When you need to delete a file using NodeJS, You can use the fs. unlink() or fs. unlinkSync() method.
NTFS is a journaled file system. A journal is basically equivalent to a transaction log in a database. It'll ensure consistency and integrity of the file system structures like a database does for its tables. While File.Delete doesn't have any transactional code at the high level, NTFS does maintain transactional integrity at the filesystem level. This may not be true for other file system drivers.
