Can i get all the folders and files (under all level) inside a main folder using CAML

Question

I have the following CAML query where i am trying to get all the files and folders that are directly and indirectly added to the folder named FolderA:-

camlQuery6.ViewXml = "<View Scope=\"RecursiveAll\"><Query><Where><Eq><FieldRef Name=\"FileDirRef\" /><Value Type=\"Text\">" + context.Web.ServerRelativeUrl + "/ArchDocs/FolderA"</Value></Eq></Where></Query></View>";
ListItemCollection collListItem6 = context.Web.GetList(context.Web.ServerRelativeUrl + "/ArchDocs").GetItems(camlQuery6);
context.Load(collListItem6, items => items.Include(
      item => item.Id,
      item=>item["FileDirRef"],
      item => item["Title"],
      item => item["DealStage"]));

the above CAML will only return the main folder under /sites/projects/ArchDocs/FolderA, but will not return any of the sub-folders and files.. so can anyone advice how i need to modify the CAML, or CAML does not support this?

Answer 1

The query is only returning items directly in that folder because your CAML is set to only return items where the FileDirRef (or Folder Path) is equal to /sites/projects/ArchDocs/FolderA, anything that is in a subfolder would have a different FileDirRef, such as /sites/projects/ArchDocs/FolderA/SubFolder1, which would not be equal to the path you specified. What you want to do, is instead of the <Eq> operator element, you want to use <BeginsWith>. Note, you also appear to have syntax error with your string concatenation context.Web.ServerRelativeUrl + "/ArchDocs/FolderA"</Value>

Give this a try:

camlQuery6.ViewXml = "<View Scope=\"RecursiveAll\"><Query><Where><BeginsWith><FieldRef Name=\"FileDirRef\" /><Value Type=\"Text\">" + context.Web.ServerRelativeUrl + "/ArchDocs/FolderA" + "</Value></BeginsWith></Where></Query></View>";
ListItemCollection collListItem6 = context.Web.GetList(context.Web.ServerRelativeUrl + "/ArchDocs").GetItems(camlQuery6);
context.Load(collListItem6, items => items.Include(
      item => item.Id,
      item=>item["FileDirRef"],
      item => item["Title"],
      item => item["DealStage"]));
