Probably the best free soft would be 7zip.
There is also WinRar, but I don't think it's that much better, and it's non-free.
Compression can be both internal and external. Internal compression is data compression within a file format, like the data compression found in image or video files. External compression involves compressing files or folders as a whole using software tools, such as ZIP or RAR, to reduce their overall size for storage or transfer.
Compression software is software used to compress data in some way. This can be either through a network connection (such as a web accelerator), a file archiver (such as WinRAR or WinZip), or a media coder (from WAV to MP3 or MPEG to DivX).
I feel TITAN Archive is the Best software for Data Archiving. Since it Supports Compliance and Data Management Needs.

The best data analysis software for Windows is Matlab. It is the most used commercial data analysis software worldwide. It is a high level language and interactive environment for numerical computation, visualization, and programming.
Data compression techniques are used to reduce the size of files and data for efficient storage and transmission. Common methods include lossless compression, which preserves all data accurately, and lossy compression, which sacrifices some data to achieve higher compression rates. Examples of compression algorithms include ZIP for general purpose compression, JPEG for image compression, and MP3 for audio compression.
Staples sells a very reputable software package for data restoring. Norton antivirus also has a very good software download to restore your computer's data.
Compression Software
File compression uses software algorithms to reduce file size by reducing the bit-rate of a file. Lossy compression takes it a bit further and lowers the quality of thr file to make it even smaller. Lossy compression is commonly used for media files, but would not be appropriate for other types of files.
Data Compression is a technique to minimize the space used by data in storing. So when we do compression of data, no data is loss.
