If you download a compressed archive like Tar , CAB before using the files you need to extract them.How if you directly get the files of archives that also online without installing any additional software to open/extract the archives ?
As we know windows by default supports ZIP archives(using zipfldr.dll ).We can build or extract ZIP files very easily without any third party software.But when we have to deal with RAR,CAB,TAR etc file archives we need some third party software.
But now you can extract such files without any software.WobZip is a web application which allows you to extract several file archives from your computer (by uploading) or directly from a web URL.This means you can extract the archive before you download it.
They support 7z, ZIP, GZIP, BZIP2, TAR, RAR, CAB, ISO, ARJ, LZHCHM, Z, CPIO, RPM, DEB and NSIS File formats to extract.
They have kept file limit of 100 MB Maximum.
