About formats

EXP (Melco) is a machine embroidery file format developed by Melco, a company founded in 1972 that pioneered the commercial embroidery industry. The format stores stitch data as a series of relative coordinate movements using a compact binary structure, with each record encoding the needle's horizontal and vertical displacement along with control flags for stitch type, color changes, and machine stops. EXP files use a straightforward sequential layout — stitch records follow one after another without complex headers or nested structures, making the format reliable and fast to process on embroidery machine controllers. Melco developed the format for their commercial multi-head embroidery machines, widely deployed in contract embroidery shops, uniform manufacturers, and promotional product companies. One advantage is efficiency for commercial production — the lean binary structure minimizes file size and loading time, important when operators run hundreds of designs daily on multi-head machines. The format's association with Melco's professional-grade equipment gives it credibility in the commercial embroidery sector, where reliability and speed are prioritized. Most professional digitizing software — including Wilcom, Pulse, and Hatch — supports EXP export, ensuring designs from any major platform can target Melco equipment. While EXP lacks embedded thread color metadata, its simplicity and industry acceptance have sustained its use across decades of commercial embroidery production.

MOBI is an ebook format originally developed by Mobipocket SA, a French company founded in 2000 that was later acquired by Amazon in 2005. The format builds on the PalmDOC/PDB container structure, adding support for HTML-based content markup, embedded images, a DRM layer, and a JavaScript subset for limited interactivity. MOBI files use a record-based database architecture inherited from Palm OS, with a header structure containing metadata like title, author, publisher, and language followed by compressed HTML content records. The format became the foundation of Amazon's early Kindle ecosystem — the original AZW format used on first-generation Kindles was essentially MOBI with Amazon's own DRM wrapper. MOBI supports reflowable text with basic formatting including bold, italic, headings, lists, and tables, as well as internal hyperlinks and a built-in table of contents. One advantage is broad device compatibility: MOBI files are recognized by Kindle devices and apps spanning over a decade of hardware, as well as numerous third-party readers on desktop and mobile platforms. The format's lightweight structure is another strength — even long novels produce compact files that load quickly on modest hardware. While Amazon has since moved to the more capable AZW3/KF8 format for new publishing, MOBI remains widely circulated in existing ebook libraries and continues to be produced by conversion tools like Calibre for maximum Kindle compatibility.
