FXP is an acronym for File eXchange Protocol, a protocol that is used for transferring computer files between different systems. Some synonyms for FXP include File Transfer Protocol (FTP), Secure File Transfer Protocol (SFTP), and Hypertext Transfer Protocol (HTTP). These protocols are similar to FXP in that they are designed to move data between computers, but each has its own unique features and characteristics. FTP, for example, is one of the oldest protocols used for file transfer. SFTP, on the other hand, is a more secure version of FTP that uses encryption to protect data in transit. HTTP is a protocol that is commonly used for transferring files over the internet.
