This line below in the cmd shell unzips the content of a zip file D:\zips\test.zip in the folder C:\Users\mike\Desktop\test:
C:\Program Files\7-Zip\7z.exe e -oC:\Users\mike\Desktop\test D:\zips\test.zip
If I use Run nothing happens with the ouput error 1:
Run["C:\\Program Files\\7-Zip\\7z.exe e -oC:\\Users\\mike\\Desktop\\test D:\\zips\\test.zip"]
This is an expansion of my comment.
With its use of backslashes and spaces in directory names, the Windows OS a bit of an odd ball. If you open a CMD prompt and try to execute the 7z.exe help (-h) without quotes, then I get the following error:
C:\Users\Tim>c:\Program Files\7-Zip\7z.exe -h
'c:\Program' is not recognized as an internal or external command,
operable program or batch file.
Now, the CMD prompt will automatically add quotes if you start typing a path to an executable and these quotes will need to be represented in the Run[] function. The actual CMD prompt will look like this
C:\Users\Tim>"c:\Program Files\7-Zip\7z.exe" -h

The following Mathematica code should execute 7z.exe help and read the output.
outputfile = CreateFile[];
Run["\"C:\\Program Files\\7-Zip\\7z.exe\" -h >>" <> outputfile];
stext = OpenRead[outputfile];
ReadString[stext]
Close[stext];
DeleteFile[outputfile];

Run["echo testing > test.txt"]which should create a text file in your Documents folder. $\endgroup$
