File extension .cab
Category Compressed File
Description The CAB file extension is a compression format developed by Microsoft. Originally used to minimise the number of floppy disks required to hold installation data, the file format is now used to minimise the size of files downloaded from the web. The CAB format offers effective compression because it compresses across multiple files ignoring the boundaries between the files. CAB files are often linked with self extracting files due to the ease with which they can be recognised as CAB files.

Technical Details The CAB file permits three types of compression: Quantum, LZX and DEFLATE. Microsoft provide the ability to apply a digital signature to a CAB file. This allows a user to verify the authenticity of the file. CAB files are not constrained by a maximum file size that some compression files face. It is possible to spread a CAB file over multiple CAB files. A limitation of a CAB file is that it needs to be recreated every time it is changed, whereas other compressed formats allow for a file to be updated based on additions, removals or edits.

File extension .7z
Category Compressed File
Description First released in 1999, the .7z file extension was first released alongside the 7Zip open source archiving application. The format allows for any conversion, encryption or compression method to be applied. Because any of these methods can be used, the format is effectively future proofed. The file type also allows for its size to be extremely large and can achieve high rates of compression.
