DGCA

In 2001, Shin-ichi Tusuta, a Japanese who created a freeware compression utility named DGCA, the next generation of GCA. This is data compression software or source coding wherein fewer bits were used in processing of encoding information like the ZIP file format which stores various files in one file. Compression is helpful in reducing the consumption of transmission bandwidth or hard disk space which are both expensive. However, in viewing or hearing compressed data, decompression must first be done and this process can be damaging to other applications. This application therefore involves trade-offs which includes amount of distortion being introduced, compression degree and the resources required in compressing and uncompressing data. The encoding scheme should be understood, as with any communication in order to process the data compression between the sender and the receiver. It has a stronger encryption and Unicode filenames and has a better compression ratio that ZIP, but it is not a major compression format. DGCA opens with Windows.
