  • Yes, it’s possible without multi-tenancy, but File Management Pro’s built-in “total size limit” feature is tenant-based (so you won’t get an “out of the box” per-user quota the same way).
  • In a tiered architecture, your SecondaryUI.web should act only as a UI client. The real configuration + storage decisions must be done in the main Host (HttpApi.Host) because that’s where the File Management HTTP endpoints run and where files are actually stored.

  ---

  • Configure File Management Pro and its BLOB container in the main Host application (*.HttpApi.Host), not in SecondaryUI.web.
  • In *.HttpApi.Host, configure the File Management module’s blob container (example uses file system; you can also use Database/Azure/etc.):

  using Volo.Abp.BlobStoring;
  using Volo.FileManagement.BlobStoring;
  
  Configure<AbpBlobStoringOptions>(options =>
  {
      options.Containers.Configure<FileManagementContainer>(c =>
      {
          c.UseFileSystem(fileSystem =>
          {
              fileSystem.BasePath = Path.Combine(
                  hostingEnvironment.ContentRootPath,
                  "FileManagementStorage"
              );
          });
      });
  });
  

  • Then, implement a “user root directory” concept in the Host:
    • On first access, create a root folder for the current user (e.g., name = user-{CurrentUser.Id}) under a known parent (or as a root directory).
    • Ensure every operation from SecondaryUI.web is scoped to that directory (either by:
      • customizing/overriding the relevant application services / policies in the Host, or
      • building thin wrapper app services that call FileManager but always force directoryId = userRootDirectoryId).

  Conceptually (Host-side), it looks like:

  // PSEUDO: illustrating the pattern using FileManager + DirectoryDescriptor repository
  
  var userId = CurrentUser.GetId();
  var userRootName = $"user-{userId}";
  
  // find or create user's root directory
  var userRoot = await _directoryRepo.FirstOrDefaultAsync(x =>
      x.Name == userRootName && x.ParentId == null && x.TenantId == null);
  
  if (userRoot == null)
  {
      userRoot = await _directoryRepo.InsertAsync(
          new DirectoryDescriptor(GuidGenerator.Create(), userRootName),
          autoSave: true);
  }
  
  // always upload into userRoot.Id
  await _fileManager.CreateAsync(fileName, contentType, content, userRoot.Id, /*tenantId*/ null, overrideExisting: true);
  

  Enforcing “each user only sees their own directory”

  • Do the enforcement on the server (Host) using ABP authorization / resource-based rules or by hard-scoping queries/commands to the current user’s directory.
  • Do not rely on hiding UI elements in SecondaryUI.web; users can still call APIs.

  ---

  • Built-in quota: File Management Pro explicitly documents quota/size limit at the tenant level (multi-tenancy scenario).
  • Without multi-tenancy: implement your own per-user quota in the Host, for example:
    1. Before allowing upload, calculate current usage for that user (sum file sizes under user’s root directory).
    2. Reject the upload if currentUsage + newFileSize > userLimit.
    3. Store userLimit in your own setting/entity (per-user).
  • This approach works in single-tenant (no multi-tenancy) solutions, but it’s custom (not the tenant quota feature).

  To limit a user to only their own folder, you should not rely on “normal” (RBAC) permissions alone (like FileManagement.Directories, FileManagement.Files, etc.). Those permissions apply to all directories/files.

  Instead, use Resource-Based Authorization in ABP and treat each directory (folder) as a resource instance.

  1) Define a “Directory resource” permission

  In your PermissionDefinitionProvider, define:

  • a management permission (who can share/manage access),
  • resource permissions (view/edit/delete) bound to a directory instance.

  public class MyPermissionDefinitionProvider : PermissionDefinitionProvider
  {
      public override void Define(IPermissionDefinitionContext context)
      {
          var group = context.AddGroup("MyApp");
  
          var fileGroup = group.AddPermission("MyApp.FileManagement");
          fileGroup.AddChild("MyApp.FileManagement.ManageDirectoryPermissions");
  
          context.AddResourcePermission(
              name: "MyApp.FileManagement.Directory.View",
              resourceName: "MyApp.FileManagement.Directory",
              managementPermissionName: "MyApp.FileManagement.ManageDirectoryPermissions"
          );
  
          context.AddResourcePermission(
              name: "MyApp.FileManagement.Directory.Write",
              resourceName: "MyApp.FileManagement.Directory",
              managementPermissionName: "MyApp.FileManagement.ManageDirectoryPermissions"
          );
      }
  }
  

  2) Enforce it in the Host app service (server-side)

  Whenever you return directory content or allow upload/download/move/delete, check the permission against the directory instance (resource key = directory id).

  public class MyDirectoryAppService : ApplicationService
  {
      public async Task<DirectoryContentDto> GetContentAsync(Guid directoryId)
      {
          // Throws if user is not granted for this specific directory
          await AuthorizationService.CheckAsync(
              resource: directoryId.ToString(),
              policyName: "MyApp.FileManagement.Directory.View"
          );
  
          // Then call File Management services/repositories as needed...
          // return await _directoryDescriptorAppService.GetContentAsync(...);
      }
  }
  

  In ABP, the point is: check permission using (resourceName + resourceKey), not just [Authorize("Some.Permission")].

  3) Make “user folder” ownership automatic (no manual sharing)

  When you create the user’s root directory (e.g., user-{CurrentUser.Id}), grant resource permissions to that same user programmatically:

  • grant Directory.View and Directory.Write to provider U (user) with providerKey = the userId,
  • resourceKey = directoryId.

  (How you store and manage these grants is handled by ABP’s resource permission infrastructure; your job is to define the resource permissions and enforce them.)

  4) (Optional) Use ABP’s built-in UI to manage per-folder sharing

  If you want admins to open a “Permissions” dialog for a specific folder and share it with other users/roles, ABP provides a ready modal for resource permission management (same concept as the docs example). This is the cleanest way to manage “folder sharing” without writing your own UI.

  Notes specific to File Management Pro

  • File Management Pro by default is not “per-user folder isolated” automatically. You implement this by wrapping/customizing the application service layer in the Host and checking resource permissions before calling module services.
  • This works fine without multi-tenancy.

  Hi,

  Thanks for the details.

  Yes, this scenario is possible without multi-tenancy.

  • In a tiered solution, SecondaryUI.web should be treated as another UI/remote-client application. The File Management HTTP endpoints and the actual file storage are on the server side, so the BLOB provider configuration for FileManagementContainer should be done in HttpApi.Host, not in SecondaryUI.web.
  • File Management's built-in storage size limit is tenant-based. In a non-multi-tenant application, this effectively becomes a single host-wide limit, not a per-user limit.

  To make the project split clearer:

  • The exact project/package list depends on whether SecondaryUI.web is MVC/Razor Pages, Blazor, or another UI setup, so we should not prescribe one fixed package list without seeing the solution structure.
  • However, the responsibility split should be like this:
  • On the server side, the File Management backend and FileManagementContainer BLOB provider configuration should exist in the application that exposes the File Management HTTP API and stores the files, which in your case is HttpApi.Host.
  • On SecondaryUI.web, you should use the UI package for the framework you are using, and if this application works as a remote client, it should consume the File Management remote API through the client/proxy side (Volo.FileManagement.HttpApi.Client or the equivalent proxies added by the module installation).
  • For example, the File Management module provides separate UI-side packages such as Volo.FileManagement.Web for MVC/Razor Pages and Volo.FileManagement.Blazor for Blazor, while remote API client proxies are provided by Volo.FileManagement.HttpApi.Client.
  • So, the important point is not that SecondaryUI.web should have no File Management references; it can have the UI/client-side references. The important point is that storage provider configuration and actual persistence behavior belong to the host side.
  • For a second MVC/Razor Pages application specifically, Volo.FileManagement.Web alone is generally not enough when the real backend is on another server application. The module's JavaScript proxies and upload/download URLs target the current application's root (abp.appPath / /api/file-management/...).
  • Because of that, in this MVC/Razor Pages scenario you typically need Volo.FileManagement.Web + Volo.FileManagement.HttpApi + Volo.FileManagement.HttpApi.Client together in SecondaryUI.web.
  • In that setup, the local File Management HTTP API controllers in SecondaryUI.web receive the requests from the module UI, and those controllers can delegate to the remote application through the HttpApi.Client implementations.
  • If you build a custom reverse-proxy/base-url setup, you may organize it differently, but for the standard second MVC/Razor Pages client scenario, this clarification is important.

  For your scenario, the recommended approach is:

  1. Create one root directory for each user in the host application.
  2. Let SecondaryUI.web use the existing File Management APIs/proxies exposed by the host.
  3. Grant that user access only to their own root directory.
  4. Keep upload, download, move, and delete operations inside that user's directory tree.

  There is also an important point for your follow-up question about permissions:

  • This is already available in ABP File Management 10.2.
  • File Management already defines built-in resource permissions for directories and files.
  • These permissions are checked by the module during directory/file operations, and directory permissions can apply through the parent directory chain.
  • So you do not need to build a completely separate folder-permission infrastructure for the module itself; you mainly need to grant and manage the correct resource permissions for each user's root folder.

  So, to limit a user to only their own folder, the usual design is to:

  • give the user the basic File Management access needed to open the module,
  • create a dedicated root folder for that user,
  • grant resource permissions only for that folder (and its descendants),
  • avoid granting broad create/update/delete permissions globally unless the user should have full access everywhere.

  For the storage quota part:

  • If you want a different quota for each user, this requires customization in the host application.
  • The module's built-in storage check is based on the current tenant/host total usage, not on a specific user's folder size.
  • For a per-user quota, you should add a custom upload validation that calculates the total size under the current user's root directory and rejects the upload when the user-specific limit is exceeded.

  So, for your original questions:

  1. Configure the File Management storage provider in HttpApi.Host, and use SecondaryUI.web as the UI/client side that consumes the File Management functionality from the host.
  2. Yes, it works without multi-tenancy, but per-user quota is not built in and needs a custom implementation.

  If you want, we can also share a recommended server-side design for automatically creating the user's root folder, granting the correct resource permissions, and enforcing a per-user upload quota.

  That is great! Both the client (SecondaryUI.web) and the server are MVC based.

  Hi,

  Thanks, that clarification helps.

  Since both SecondaryUI.web and the main server are MVC-based, the recommendation becomes more specific for the standard ABP setup:

  • Keep the actual File Management backend and the FileManagementContainer BLOB provider configuration in HttpApi.Host.
  • In SecondaryUI.web, Volo.FileManagement.Web alone is typically not enough.
  • For this MVC-to-MVC client scenario, you typically need Volo.FileManagement.Web + Volo.FileManagement.HttpApi + Volo.FileManagement.HttpApi.Client in SecondaryUI.web.

  The reason is:

  • Volo.FileManagement.Web uses JavaScript proxies and upload/download endpoints against the current application's root (abp.appPath / /api/file-management/...).
  • So, in a second MVC application, those requests first hit SecondaryUI.web itself.
  • Volo.FileManagement.HttpApi provides the local File Management HTTP API controllers in that MVC application.
  • Volo.FileManagement.HttpApi.Client allows those controllers to call the real backend on HttpApi.Host through remote client proxies.

  So in practice, SecondaryUI.web acts as an MVC UI + local API facade, while HttpApi.Host remains the real storage/processing side.

  One more important point:

  • In SecondaryUI.web, make sure the remote service configuration for File Management points to the main host application.
  • The File Management module uses the remote service name FileManagement, so this should be configured against the HttpApi.Host base URL.
  • In practice, this usually means configuring RemoteServices in SecondaryUI.web's appsettings.json.

  For example:

  "RemoteServices": {
    "Default": {
      "BaseUrl": "https://localhost:44300/"
    },
    "FileManagement": {
      "BaseUrl": "https://localhost:44300/"
    }
  }
  

  • Here, https://localhost:44300/ should be replaced with your main HttpApi.Host URL.
  • Since Volo.FileManagement.HttpApi.Client registers its proxies with the remote service name FileManagement, that named endpoint is the clearest configuration.
  • Also note that ABP falls back to RemoteServices:Default if a named FileManagement endpoint is not defined. So if your Default endpoint already points to the same HttpApi.Host, a separate FileManagement section may not be strictly required.
  • The relevant ABP documentation is here: https://abp.io/docs/10.2/framework/api-development/static-csharp-clients

  The folder isolation and any per-user quota logic should still be enforced on the server side.
