Dump/Restore
| Pop | 318.35 |
|---|---|
| Vit | 8.26 |
The dump package contains both dump and restore. Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups.

RabbIT

| Vit | 31.07 |
RabbIt is a mutating, caching Web proxy used to speed up surfing over slow links like modems. It does this by removing advertising and background images and scaling down images to low quality JPEGs. RabbIT is written in Java and should be able to run on any platform. It does depend upon an image converter if image scaling is on. The recommended image converter is "convert" from the ImageMagick package.

UnZip

| Vit | 8.57 |
UnZip will list, test, or extract files from a ZIP archive, commonly found on DOS and Windows systems. A companion program, Zip, creates ZIP archives; both are part of the Info-ZIP project. Both programs are compatible with archives created by PKWARE's PKZIP or Nico Mak's WinZip, but in many cases the program options or default behaviors differ.

Hash Zip
| Pop | 49.15 |
|---|---|
| Vit | 1.00 |
Hash Zip is a compression algorithm that trades CPU time for compression ratio (emphasis on a lot of CPU time) using a hash and a few other interesting bits of data. Currently, sha1 is the hash algorithm.

Versatile Encoder
| Pop | 25.92 |
|---|---|
| Vit | 1.73 |
Versatile Encoder allows you to encode your own videos into good quality DivX files. The input can be a sequence of files (as generated by blender), a single file (if you want to recompress something), or a VCD (if you need to back up a movie). This piece of software tries to guess good defaults and to help the user in making choices.

|---|---|
| Vit | 1.00 |
Zipeg is free utility that opens and explores the contents of zip, rar, arj, and other archives. It can preview files and images before you extract them, and lets you extract only the files you want. Many documents and pictures can be emailed as zip archives.

|---|---|
| Vit | 1.00 |
IMGCrush is an image compressor. IMGCrush_GUI is a simple GUI for IMGCrush. IMGCrush can perform both lossy and lossless compression in order to achieve the file size or quality that the user requires.

wavpack
| Pop | 21.73 |
|---|---|
| Vit | 35.51 |
WavPack is a completely open audio compression format that provides lossless compression, high-quality lossy compression, and a unique hybrid compression mode. The lossless compression ratio depends on the source material, but generally is between 30% and 70%. The hybrid mode provides all the advantages of lossless compression with an additional feature. Instead of creating a single file, this mode creates both a relatively small, high-quality lossy file that can be used all by itself, and a "correction" file that (when combined with the lossy file) provides full lossless restoration. WavPack employs only well known, public domain techniques in its implementation. Methods and algorithms that have ever been patented are specifically avoided. This ensures that WavPack encoders and decoders will remain open and royalty-free.
