Definition of a File Compression Utility
A file compression utility is a software program that is used to compress or decompress files. Most often such a software program is used to compress files of various formats that are no longer being actively used and reduce their size so that they take up about 40 percent less space on hard disk. However, a file compression utility is used in many other situations, for example where large sized files of one particular format need to be compressed. Here it can be used when thousands of files of one format are created on a daily basis and these need to be compressed. For instance when image files are created as part of a scanning process, such a software program can be used to convert these normally large sized files into much smaller ones. This can result in a large amount of disc space being saved as such files can quickly overwhelm servers, especially when a scanning process is continuous and files are created daily.
Types of Files Compressed by a File Compression Utility
A file compression utility like WinZip can be used to compress a variety of file formats and is popular as it has a simple interface and is not difficult to use. When using such a software program files can be compressed and decompressed. Files that are compressed before being sent by email have to be decompressed once they are received by the recipient often by using the same file compression utility that was used to compress them. Once decompressed the files in the compressed folder will revert to their original size and no data will be lost.
How a File Compression Utility is Used to Compress Scanned Images
Many a file compression utility has been created to compress scanned images. This software in such instances is built specifically to compress files and at the same time retain their quality. This is essential as these files are often run through OCR software to convert them into text searchable files. Users can even decide what amount of image quality they want retained in the compressed files when using such a file compression utility.
