Sometimes, it so happens that, owing to the large size of some files or the large number of files stored in your computer, you are faced with the problem of shortage of virtual memory. This affects the smooth performance of the computer. It becomes extremely slow which is the cause of much inconvenience. Some of the measures taken to deal with this problem are disk defragmentation, disk cleanup, removal of old files no longer needed, and file compression. As a result of file compression the size of files is significantly reduced, which leads to increases of space in your hard disk memory; this in turn facilitates the smooth functioning of the computer.
There are many other advantages of file compression besides the increase in virtual memory. Sending files as email attachments might take a long time if the files have images or videos. This is because such files have large sizes and do not upload easily, especially on slow net connections. It is obvious that the person who downloads such a file faces the same problem. Traffic across computer networks is also slow if voluminous files are being sent. So owing to the large size of files all these activities become not only time-consuming but also cost a lot of money, not to mention the inconvenience and frustration they cause.
How does file compression work?
Computer files are coded in such in such a way that spaces are left between the coded segments. This, coupled with the repetition of information in the document, is the cause of the enormously large size of the files. File compression works by removing the redundancy. File compression tools work by removing multiple instances of occurrence of data with a single instance. This it does by placing a reference that helps in the reconstruction of the document.
