You can create a custom Javascript or java backed web-script to get the list of folders and subfolders.
Execute a search query from your custom webscript to list the folders and subfolders and write to a json object and return in response.
If you want to get all folders at any depth then, Search query would be something like this:
PATH:"/app:company_home/st:sites/cm:test-site/cm:documentLibrary//*" AND TYPE:"cm:folder"
Get the count from returned result set and to get the path for each returned nodeRefs use 'nodeService.getPath(nodeRef).toDisplayPath(nodeService, permissionService)'
If you want to get all folders at first level and then get subfolders for each folder then, Search query would be something like this:
1 Pass: PATH:"/app:company_home/st:sites/cm:test-site/cm:documentLibrary/*" AND TYPE:"cm:folder"
2 Pass:
PATH:"/app:company_home/st:sites/cm:test-site/cm:documentLibrary/cm:MyFolder/*" AND TYPE:"cm:folder"
3 Pass:
PATH:"/app:company_home/st:sites/cm:test-site/cm:documentLibrary/cm:MyFolder/cm:MySubFolder/*" AND TYPE:"cm:folder"
And so on.. depending on levels of subfolders.
Get the folders and subfolders recursively and prepare a POJO having parent and child count including the display path and convert it to JSON at the end when all folders/sub-folders are iterated.
