7-Zip command line - do not extract certain file types

Question

How do I extract all the files in a 7-Zip .7z archive EXCEPT certain file types, using the 7-Zip command line?

Example: backup.7z contains files of type:

• .xls
• .xlsx
• .doc
• .docx
• .pdf
• .txt
• .png
• .gif

Using the 7-Zip command line, how do I extract all the files from that backup.7z archive EXCEPT the .doc and .docx files?

The .7z archive contains files and folders and I want all the files and folders - EXCEPT the .doc and .docx files - to be extracted.

I am using MS Windows 7.

Use the -x (Exlude filenames) switch.

7z e backup.7z -x!.doc

---

-x (Exclude filenames) switch

Specifies which filenames or wildcarded names must be excluded from the operation.

Multiple exclude switches are supported.

Syntax

-x[<recurse_type>]<file_ref>

<recurse_type> ::= r[- | 0]
<file_ref> ::= @{listfile} | !{wildcard}

See -i (Include) switch description for information about option parameters.

Examples

7z a -tzip archive.zip *.txt -x!temp.*

adds to the archive archive.zip all .txt files, except temp. files.

Commands that can be used with this switch

a (Add), d (Delete), e (Extract), l (List), t (Test), u (Update), x (Extract with full paths)
