I know you can create a text file containing a list of files and then tell 7zip to reference this file so that it can exclude them from the archive, but I cannot find the syntax for that. Can someone help?

After a few hours of searching, I finally figured it out. Here's the switch syntax:
7z a -xr@exclude.txt backup.7z c:\whatever\*
Notice -xr instead of -x. The r indicates recursive so it can match excluded files in deep folder hierarchies. Also, the format of the text file can be at least ANSI or UTF-8.
As for the file containing the files, as OldWolf said, it's a list separated by carriage returns like this:
Telerik.Reporting.dll
Telerik.Reporting.Service.dll
Telerik.ReportViewer.WebForms.dll
Telerik.Web.Design.dll
Telerik.Web.UI.dll
*.txt
Works like a charm.

1Thanks! I was trying to do exclude with the wildcard option and it turns out I was missing the
roption. This is the correct way to exclude PNG files recursively in bash (single quotes to stop bash from expanding!and*):-xr'!*.png'(edit: single quotes instead of escape) Jul 27, 2015 at 8:48
I think you want the -x switch with @
7z a -t7z my.zip * -x@myexclusion.lst
In retrospect, I realized you may have meant you wanted the syntax for the listfile. It should be a newline separated list. You may be running into an encoding issue. 7z expects it to be in UTF-8 format, you can override that with the -scs switch or you can tell notepad to save the file in UTF-8 format

2Thanks for the reminder about file encoding. I have been puzzling for hours as to why my exclusion list was not being obeyed. I produce the file in a PowerShell script using Out-File which defaults to Unicode. Changing it to output UTF8 and suddenly everything just works.– WileCauApr 27, 2014 at 12:23
If your list is going to be really short, you can have more than one -x flag:
7z a -r CppSourceJBR.zip *.cpp .h -x!stdafx. -x!targetver.h
BTW while testing I had to keep deleting the .zip file. When I forgot that, for instance targetver.h was still in the ZIP from the last run.
