File Compression is known to be the data compression method that allows the file's local size to be reduced for saving disk space for faster and easier transmission over the internet or network. It also enables the making of a version for a file consisting of data of size that is quite smaller than the original file.

File compression is only possible via any data or file compression software that can create a compressed version for every processed file. Usually, File compression can be seen working by scanning an entire file and identifying repetitive or similar patterns and data and replacing the duplicates with one of the unique identifiers.
