ImminentFate/CompactGUI: Visual Interface for the Windows Compact.exe cmdlet
The new compact in windows 10 does special program/file compression using faster realtime codecs, and should be safe for 40GB files (unlike native NTFS compression which uses DEFLATE)

How to Effectively Use Backup Compression in SQL Server
SQL Server's backup compression allows you to save disk space by compressing backup files. Many SQL Server database administrators forget to enable this feature, thereby allowing backup files to occupy a lot of disk space. In this article, we will learn how to quickly enable the feature "Compression" on all your SQL Servers.

Virtual Roundtable on “Compression” | Public Books
Writing has been invented independently as few as three times in the history of the world: in ancient Sumer, in ancient China, and in medieval Mesoamerica. Sumerian cuneiform was likely the inspiration for Egyptian hieroglyphs. Those, in turn, inspired the early Semitic script from which all European and several Asian scripts ultimately derive.... Of the six or seven thousand world languages, fewer than a third are written. Of that third, nearly a quarter are typically written in the Latin alphabet, one of only 50 global writing systems. The alphabet today, in its most common guise—namely, this one—is thus regularly used to transcribe some five hundred languages...

Can we attribute this easy mobility to the alphabet’s efficiency in compressing sounds into symbols? Rather than the 2000–3000 characters one must know to read a Chinese newspaper fluently or the 500–1000 signs used in Sumerian and Akkadian cuneiform, only 20–30 alphabetic characters are needed to record an increasing number of languages. Yet our alphabets’ history reveals just how slippery and complex “compression” is in relation to the messages that it allegedly compresses. ...

Consider the case of vowels. Just as they are absent from most Hebrew written today, marks of vowels were not usually necessary for transcribing ancient Semitic languages. Nor were they absolutely necessary for transcribing ancient Greek; Linear B encoded vowels along with consonants in its syllabary. When Greek speakers adapted characters from the West Semitic script to systematically represent vowels, they in fact expanded the inventory of types of sounds encoded in their writing.

From Global to Local: Getting More from Compressed Sensing
While the math work was done in 2006, compressed sensing has been gaining traction in data science, particularly for IoT applications at scale. In industry, this translates to much better data with fewer expensive sensors—plus insurance against the problems of noise, sensor failure, and the generally high cost of uploading data from the edge.
