When attempting to open, move, modify, or delete the archived Creative Cloud Files folder or local project directories after cloud sync has ended, Windows or macOS may block you with an “Access Denied,” “You don’t have permission to access this folder,” or “Error 5: Access is Denied” prompt. This permissions lock occurs because the folders retained security descriptors (ACLs) bound to discontinued background service accounts, the sync engine left read-only attribute flags in place, or an OS upgrade altered your local user account identifier (UID/SID).
Fast Fix
On Windows, right-click the locked folder, select Properties > Security > Advanced, click Change next to Owner, enter your Windows username, check Replace owner on subcontainers and objects, and click Apply. On macOS, open Terminal and run
sudo chown -R $(whoami):staff "/path/to/folder".
Quick Status Snapshot
- Severity: High (prevents access to local project files, blocks asset migrations, and halts backups).
- Target Layer: Windows NTFS Access Control Lists (ACLs) and macOS POSIX ownership/Extended Attributes.
- Privilege Level: Local Administrator credentials required to take ownership and reset file permissions.
Why Local Cloud Archives Get Locked
When synchronization software manages local folders, it configures specific file-system permissions to prevent users from accidentally modifying files during mid-transfer write cycles.

[ERROR: ACCESS IS DENIED]
These permissions barriers typically occur due to three main causes:
- Orphaned Service Account SIDs: Under Windows, folders managed by background updaters often grant ownership to a local service identifier rather than your personal user account. When the service is removed, the folder is left without an active administrative owner.
- Read-Only System Attributes: Before synchronization was retired, the sync client often applied read-only attributes to root folders to preserve directory structures. If these flags are not cleared, the operating system blocks changes to the folder.
- macOS UID Mismatches Post-Migration: If you used Migration Assistant or restored from a Time Machine backup to move to a new Mac, your numerical user ID may have shifted from
501to502. While the username looks identical, macOS denies access because the underlying account identifier does not match.
If this permissions lock occurred during a recent macOS Sequoia setup, see Fixing ‘Could Not Create Local Sync Folder’ on macOS Sequoia. For broader installer permission errors, consult Error 127: Extracting Files – Permission Denied on Program Files.
Diagnostic Path: Locating the Permission Barrier

├──> Is an Adobe background process running?

└──> On macOS: Does Finder show a red 'no-entry' badge on the folder icon?
└── Cause: POSIX ownership mismatch or immutable extended flags.
└── Action: Reset ownership via chown and strip locked flags via chflags.
If you need to locate where your archived sync folders were stored before adjusting permissions, see Where are my Files? Locating the ‘Creative Cloud Files’ Archive.
Step-by-Step Resolution
Step 1: Release Active File Handles
Before modifying security properties, confirm that no background processes are holding file handles open:
- Close all Adobe applications.
- Open Task Manager (Windows) or Activity Monitor (macOS).
- Terminate any running instances of CoreSync, Adobe Desktop Service, and Creative Cloud.
Step 2: Take Ownership and Reset NTFS Permissions (Windows)
- In File Explorer, navigate to your user profile directory:
C:\Users\<Username>\ - Right-click the locked folder (e.g.,
Creative Cloud Files) and select Properties. - Go to the Security tab and click Advanced.
- At the top of the window, locate the Owner field and click Change.
- Type your current Windows username into the text box, click Check Names to validate it, and click OK.
- Check the box labeled Replace owner on subcontainers and objects.
- In the lower section, check the box labeled Replace all child object permission entries with inheritable permission entries from this object.
- Click Apply, then confirm the prompt by clicking Yes. Click OK to close the properties window.

└──────────────────────────────────────────────────────────┘
Step 3: Clear System and Read-Only Attributes via Command Line (Windows)
If taking ownership does not fully unlock the directory, clear any lingering read-only and system flags:
- Right-click the Start Menu and select Terminal (Admin) or Command Prompt (Admin).
- Run the following command to remove system and read-only attributes recursively:
attrib -r -s "C:\Users\<Username>\Creative Cloud Files\*.*" /s /d - Press Enter. You now have full access to move or delete files in the directory.
Step 4: Reset Directory Ownership and Clear Lock Flags (macOS)
- Open the Terminal app.
- Run the ownership recovery command:
sudo chown -R $(whoami):staff ~/Creative\ Cloud\ Files - Enter your macOS account password when prompted.
- If files remain unmovable, remove any immutable file-system flags (
uchg) left behind by sync daemons:chflags -R nouchg ~/Creative\ Cloud\ Files - Ensure write permissions are fully granted across the directory:
chmod -R 755 ~/Creative\ Cloud\ Files
Step 5: Migrate Assets Safely
Once your folder permissions are unlocked, migrate your files to a clean, unmonitored directory on your hard drive, an external SSD, or a local server. To automate this move and update any broken project links automatically, follow the procedures in How to Use the Adobe Asset Migration Tool (2026 Version).
Hard Stops
- Do not grant “Everyone” Full Control permissions on your entire
C:\Users\<Username>or/Users/<Username>parent folder. Lowering security permissions on your root user profile exposes sensitive system credentials, SSH keys, and application caches to unauthorized local processes. Only apply permission adjustments to the specific locked folder.
