This allows us to preserve directory structures, permissions, etc. File split is the simplest and most efficient way to securely fit in a mandatory output size, rather than trying to improve compression ratio with slower/heavier algorithms/settings in the hope to For example, an archival program would allow you to take a directory of files and archive them into one file that you can then send as an email with a single File Explorer Uses Backslashes To Separate Locations In A File Path. While it never approaches gzip in terms of decompression speed, it is usually significantly faster at decompressing than bzip2.
