BATCH Zip files in placeIn this case we are using 7zip command line version to compress files in place.
WHAT IS INPLACE COMPRESSION? If I have some files c:\files\file1.txt c:\files\file2.txt c:\files\folder1\file1.txt c:\files\folder2\file2.txt It will compress them and leave them as c:\files\file1.txt.7z c:\files\file2.txt.7z c:\files\folder1\file1.txt.7z c:\files\folder2\file2.txt.7z WHY WOULD YOU WANT TO DO THIS? 1. running low on HD space 2. you want to archive data onto DVDs ADVANTAGES 1. preserve folder structure 2. for DVD archival, zipping everything into 1 big file is a bad idea. if the disc gets the smallest scratch and one byte is unreadable it screws the integrity of the entire disc. If you zip everything in place, if one file gets corrupted, it doesn't effect any of the other files.
