Techopedia explains Hidden File
Most operating systems provide ways to hide files and file directories. However, in most operating systems, file management utilities allow users to explore hidden files. Software applications are also available for hiding and unhiding files and file directories.
In the case of Apple computers, the files are hidden with the help of the ResEdit utility. In the case of Microsoft operating systems, hidden files appear as faint icons or ghost icons. In most operating systems, one can hide files by turning on the special hidden attribute.
There are few reasons for applications and operating systems supporting the hidden file concept. One of the main reasons is to reduce the probability of users accidentally deleting, modifying or corrupting critical configuration or system files. It also prevents casual snoopers from accessing files which are important for the user or the network. Another reason is that hiding files and objects helps in reduction of visual clutter in the file directories and helps users in easy and convenient locating of files and directories.
