a (Add) command

Adds files to archive.


7z a archive1.zip subdir\

adds all files and subfolders from folder subdir to archive archive1.zip. The filenames in archive will contain subdir\ prefix.

7z a archive2.zip .\subdir\*

adds all files and subfolders from folder subdir to archive archive2.zip. The filenames in archive will not contain subdir\ prefix.

cd /D c:\dir1\
7z a c:\archive3.zip dir2\dir3\ 
The filenames in archive c:\archive3.zip will contain dir2\dir3\ prefix, but they will not contain c:\dir1\ prefix.
7z a Files.7z *.txt -r

7-Zip doesn't use the system wildcard parser. 7-Zip doesn't follow the archaic rule by which *.* means any file. 7-Zip treats *.* as matching the name of any file that has an extension. To process all files, you must use a * wildcard.
