You probably need to create some java utility class which could get sitename iterate though it's all documents of document library and calculate total size occupied.
This is really a very useful usecase but I am not able to recollect any out of box feature though which this can be achieved.Can anybody else share their thoughts on that?

It would be quite easy to do with a script that leverages OpenCMIS (Java) or cmislib (Python).

For example, here is a Groovy script from the CMIS & Apache Chemistry in Action book that dumps the descendants of a folder:
https://github.com/fmui/ApacheChemistryInAction/blob/master/chapter2/listing2.2.getDescendants.groovy

You could easily modify that to compute a running total of the value of each child's "cmis:contentStreamLength" property.

Thanks jpotts, I created a tool that recovers recursive CMIS:contentStreamLength from all contents of a folder

Great Job Federico,
It would be really helpful to other members if you could share your tool.

this is my testcode


public void getDimension() throws Exception{
      String parentFolder = "documentLibrary";
      String site = "workspace://SpacesStore/48299b30-d909-41e4-b7c7-73a504d5161d";
      Session session = CmisUtil.createCmisSession(ALFRESCO_USER, ALFRESCO_PWD, ALFRESCO_CMIS_URL);
      RepositoryCapabilities caps = 
        session.getRepositoryInfo().getCapabilities();
      
      Folder folder = CmisUtil.getFolderInSite(session, parentFolder, site);

      if (!caps.isGetDescendantsSupported()) {
         throw new Exception("\n Warning: getDescendants " +
                  "not supported in this repository");
      } else {
         System.out.println("\ngetDescendants " +
                  "is supported on this repository.");

         
          for (Tree<FileableCmisObject> t : folder.getDescendants(-1)) {
              printTree(t , "");
          }
          System.out.println("\nSize of " + 
               folder.getName() + ": " + size);
      }  

   }
private static void printTree(Tree<FileableCmisObject> tree, 
             String tab) throws Exception {
         long value = 0;
         for(Property<?> property : tree.getItem().getProperties()){
            String queryName = property.getQueryName();
              if (queryName.equalsIgnoreCase("cmis:contentStreamLength")){
                 Object obj = property.getFirstValue();
               BigInteger bi = (BigInteger) obj;
               value = bi.longValue();
               size = size + value;
               break;}
         }
         System.out.println("Size of " + 
               tree.getItem().getName() + ": " + value);
            
         
          for (Tree<FileableCmisObject> t:  tree.getChildren()) {
              printTree(t, tab + "  ");
          }

Thank you for all, but when I try to run your code I got the error:

2 compilation errors:

Apparent variable 'size' was found in a static scope but doesn't refer to a local variable, static field or class. Possible causes:
You attempted to reference a variable in the binding or an instance variable from a static context.
You misspelled a classname or statically imported field. Please check the spelling.
You attempted to use a method 'size' but left out brackets in a place not allowed by the grammar.
