Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:
This means that compressed archives with the UC2 file extension can hold almost 1 million files. .uca PerfectCompress [17] Windows: Windows: No Based on PAQ, RZM, CSC, CCM, and 7zip. The format consists of a PAQ, RZM, CSC, or CCM compressed file and a manifest with compression settings stored in a 7z archive. .uha UHarc DOS/Windows: DOS/Windows ...
It does include models for color BMP, TIFF and JPEG files, so compresses these files better. The primary difference from PAQ6 is it uses a neural network to combine models rather than a gradient descent mixer. Another feature is PAQ7's ability to compress embedded jpeg and bitmap images in Excel-, Word- and pdf-files.
When audio files are to be processed, either by further compression or for editing, it is desirable to work from an unchanged original (uncompressed or losslessly compressed). Processing of a lossily compressed file for some purpose usually produces a final result inferior to the creation of the same compressed file from an uncompressed original.
ACE – ace: ACE compressed file; ALZ – ALZip compressed file; APK – For Android see ABB/APK above (APK/Android apps also usable in Windows 11); The Alpine Linux distribution also use .apk files as a package format but then with un unrelated definition as in Android. They are often called "a-packs". APPX – Microsoft Application Package ...

Microsoft compressed file in Quantum format, used prior to Windows XP. File can be decompressed using Extract.exe or Expand.exe distributed with earlier versions of Windows. After compression, the last character of the original filename extension is replaced with an underscore, e.g. ‘Setup.exe’ becomes ‘Setup.ex_’. 46 4C 49 46: FLIF: 0 flif
Compressed dump files are significantly compressed, thus after being decompressed will take up large amounts of drive space. A large list of decompression programs are described in comparison of file archivers. The following programs in particular can be used to decompress bzip2, .bz2, .zip, and .7z files. Windows
