How do I create seperate zip files for each selecterd file/dir in 7zip?

Question

This is the internal zip packer from Total Commander:

However I want to use my 7zip packer. When I selecet 5 files, I get 5 seperate .zip archives for each selected file. How do I do that in 7zip?

Answer 1

I am not sure you can do what you are suggesting using the graphical user interface, but you can certainly from the command line:

FOR %i IN (*.*) DO 7z.exe a "%~ni.7z" "%i"

You would need to change directory (the cd command) to the F:\Downloads directory first, or whatever directory you would want to perform the mass compression. Also, it is easy enough to substitute in *.exe or whatever extension you want to filter for to just compress those documents.

And the secret decoder ring:

• %i is a variable that holds the file name for each step in the loop
• (*.*) is the selection criteria, it could easily be *.exe or similar
• 7z.exe is the command line version of 7-Zip
• %~ni - this expands the %i variable to just the file name - no extension

If you want to encapsulate this inside of a batch file, the only change you will need to make is to double escape the %i variable:

FOR %%i IN (*.*) DO 7z.exe a "%%~ni.7z" "%%i"

I like Goyuix's answer. However, if you are using Windows 7 (or have Power Shell installed) and also use the command-line version of 7-zip, 7za.exe, then you can run this command:

dir | ForEach-Object { & "7za.exe" a $_.BaseName $_.Name }

You can also change "dir" to "dir *.exe" to only select executable files.

One nice thing about Power Shell is that you are working with objects instead of strings. So you could get really specific if you wanted to. For example:

dir *.csv | ? { $_.Length -lt 18900 -and $_.LastWriteTime -ge [DateTime] "07/01/2011" } | ForEach-Object { & "7za.exe" a $_.BaseName $_.Name }

This will only include files that:

1. have a csv extension
2. less than 18,900 bytes in size
3. last modified on or after 7/1/2011

EDIT If you want zip files instead of 7-zip files, use InfoZip's zip.exe instead.
