Compressing Files to Save Space

Binary Compression

If you need to save space on your Flash-drive-based Linux OS. you might consider UPX, self-described as the "Ultimate Packer for eXecutables".

UPX is free and provided under the terms of the GPL. It uses a proprietary compression algorithm, the NRV compression library, but can be used with reduced efficiency with the UCL compression library.

It offers very fast in-place decompression and is available for several platforms other than Linux, including ARM, MIPS, PowerPC, DOS and Win32.

For Win32 platforms, there is a GUI version (download here), but it uses an older version of UPX as its base which should not be a problem if all you are only compressing Win32 binaries.

The command line version works on all supported executable formats in all OS versions.

Data Compression

If you just need to compress non-executable files, 7-Zip is a file archiver with the high compression ratio. The program only supports the 7z, ZIP, GZIP, BZIP2 and TAR for packing, but unpac…

And lmgtfy stands for "Let Me Google That For You" in case you missed the joke.

Funny.
Useful.
Satisfying.

BTW, the Linux solution would be a LiveCD version of Knoppix using BitDefender.

Here's the main site.

And the link to the RPM and DEB downloads.

And the link to the current LiveCD. The MD5SUM of the ISo image is 2404d4abeb23532ef842d940ccc3aeaa.

Of course, you could build your own LiveCD.

But even better, use TRK,  the Trinity Rescue Kit, a bootable Linux CD that offers several virus scanners as well as Windows cleaning, password and rescue utilities plus a Linux distro with ssh, file-sharing, backup a…
