• Hey Guest Did you know in signal processing, data compression, source coding or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information.

SecureZIP Express

Finding a good free alternative to Winzip can be a hard task, but SecureZIP Express seems to have it cracked. Anyone who has used a compression tool before will be familiar with SecureZIP Express' layout. The program's main interface is easy to navigate and customizable. It also has a wizard function for three of the main tasks you are likely to use the program for, so even total beginners will quickly be able to get to grips with the basics.

As well as compressing and decompressing, SecureZIP Express allows you to email your files directly and provides extensive security options, ranging from passwords and recipient lists to your own digital certificate, which can be downloaded separately for free. The certificate is valid for one year and comes with an online tutorial for those not familiar with the concept.

SecureZIP Express also tests files, to make sure that every thing is in order, before or after modifying them, as well as allowing you to carry out other tasks, such as updating files from saved versions and creating favourites.
