Origin of word "xfered" [duplicate]

Why do some words have “X” as a substitute?

I came upon the word "xfered" recently. From what I gather, it means "transferred", and I believe it is used in computer-related areas. Am I correct and does anyone know the origin of this word?

Solution 1:

xfer has long been a popular contraction for transfer in computer networking; in the early days, many operating systems had severe (e.g. 8 letter) restrictions on the length of filenames and commands, which often compelled such abbreviations. The earliest appearance of xfer in computing that I am aware of is connected to FTP, a network protocol which predates the public Internet, having been proposed as a standard in 1971. WU-FTPD, an early implementation of FTP developed at Washington University, stores details of file transfers in a file called xferlog, whose format has become a standard among later implementations because of the large number of tools that were written to analyse and report on xferlog data.

Solution 2:

The prefix trans- means across.

An X is a type of cross (one line is drawn across the other).

To replace trans- with an x is simply a short-hand that has gained currency.
