About formats

CCX (Corel Compressed Exchange) is a compressed vector clipart format developed by Corel Corporation, introduced alongside CorelDRAW 5 in 1994. The format is essentially a compressed variant of CMX (Corel Presentation Exchange), packaging vector artwork, embedded bitmaps, and metadata into a smaller file suitable for distribution on CD-ROM clipart collections and online galleries. CCX files use the same underlying data structure as CMX but apply compression to reduce storage requirements — an important consideration during the 1990s when clip art libraries containing thousands of images shipped on capacity-limited media. Corel distributed vast collections of CCX clipart with CorelDRAW suites, and the format became synonymous with the extensive ready-made graphic libraries that distinguished Corel's product offerings. The artwork stored in CCX files ranges from simple geometric shapes to detailed illustrations, covering categories like business, nature, people, symbols, borders, and decorative elements. One advantage is compact storage — compression allows large clipart libraries to occupy significantly less disk space than equivalent uncompressed vector files. The ready-to-use nature of CCX content is another strength, providing designers with drag-and-drop artwork that scales cleanly to any size without quality loss, inheriting the resolution independence of the underlying vector data. While the format saw its peak usage during the CorelDRAW 5 through 12 era, CCX files remain openable in current versions of CorelDRAW and can be converted to modern formats.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.
