   en.wikipedia.org/wiki/ZIP_(file_format)

   ZIP files generally use the file extensions.zip or .ZIP and the MIME media type application/zip. [1] ZIP is used as a base file format by many programs, usually under a different name. When navigating a file system via a user interface, graphical icons representing ZIP files often appear as a document or other object prominently featuring a ...

   Linux, macOS, Windows Genozip, a compressor for genomic file formats such as FASTQ, BAM, VCF and others. [4].gz application/gzip [5] gzip: Unix-like GNU Zip, the primary compression format used by Unix-like systems. The compression algorithm is Deflate, which combines LZSS with Huffman coding. .lz application/x-lzip lzip: Unix-like

4. CMD file (CP/M) - Wikipedia

   en.wikipedia.org/wiki/CMD_file_(CP/M)

   The executable loader and relocator in CP/M-86 and related operating systems can test the first byte in the file, which happens to be the type byte of the first table entry in a CP/M CMD file, to have a value of 1 to 9 before accepting it as a valid CP/M CMD file. [2] ASCII values smaller than 10 are rarely or never used in batch scripts, so ...

5. 7-Zip - Wikipedia

   en.wikipedia.org/wiki/7-Zip

   The file manager has a toolbar with options to create an archive, extract an archive, test an archive to detect errors, copy, move, and delete files, and open a file properties menu exclusive to 7-Zip. The file manager, by default, displays hidden files because it does not follow Windows Explorer's policies.

6. Comparison of executable file formats - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_executable...

   This is a comparison of binary executable file formats which, once loaded by a suitable executable loader, can be directly executed by the CPU rather than being interpreted by software. In addition to the binary application code, the executables may contain headers and tables with relocation and fixup information as well as various kinds of ...

7. Executable compression - Wikipedia

   en.wikipedia.org/wiki/Executable_compression

   Executable compression used to be more popular when computers were limited to the storage capacity of floppy disks, which were both slow and low capacity media, and small hard drives; it allowed the computer to store more software in the same amount of space, without the inconvenience of having to manually unpack an archive file every time the ...

8. Solid compression - Wikipedia

   en.wikipedia.org/wiki/Solid_compression

   On newer formats such as 7-zip, there is a solid block size option that allows for the concatenated data block to be split into individually-compressed smaller blocks, so that only a limited amount of data in the block must be processed in order to extract one file. Parameters control the maximum solid block window size, the number of files in ...

9. Data compression ratio - Wikipedia

   en.wikipedia.org/wiki/Data_compression_ratio

   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:
