This guide explains the operation of the blacklist (blacklisted) in the desktop app kDrive (macOS / Windows / Linux) and in which cases certain local files or folders are no longer taken into account for synchronization.

Preamble

• A file or folder placed on the blacklist by the application has a suffix in its name of the form _blacklisted.
  • This means that the application ignores this item during synchronization operations and are therefore not transferred to kDrive Web.
  • This mark remains active as long as the cause of the block has not been corrected.
• If an excluded folder cannot be deleted locally, it may be automatically added to the blacklist.
  • In this case, you can either delete it manually, or reactivate its synchronization in the application settings.
• Once the problem is resolved (for example after deleting a duplicate, correcting permissions, or reactivating an excluded folder), simply remove the suffix _blacklisted from the name of the item to have it taken into account again in the synchronization.
• These mechanisms ensure the stability of the synchronization process and prevent repeated errors related to inaccessible, duplicate, or system-incompatible files.

Examples of blacklisting

In some cases, a local item may be placed on the blacklist:

• Dehydrated placeholder (Lite Sync only): a placeholder file (not fully downloaded) is added to the blacklist to prevent it from being sent to kDrive Web.
• Already existing creation on the remote drive: if the creation of a file or folder fails because an identical item already exists on kDrive Web, the local item is marked as blacklisted.
• Insufficient server-side permissions: when a file or folder is created locally but the backend refuses to propagate it (for example in Common documents), the local item is placed on the blacklist.
• Folder excluded from synchronization: if a folder has been unchecked in the kDrive desktop interface, the application attempts to delete it locally if it is still present. If this fails, it is placed on the blacklist.

A blacklisting can also occur due to incompatible file names: characters such as the tilde ~, the slash /, the backslash \, certain system files such as System Volume Information or certain temporary or technical extensions (.idlk, .parms.db, .directory, ._*, etc.).

Rename these items before restarting synchronization.

Correct an item blacklisted

To recognize them:

• Identification: the suffix _blacklisted in the name of the file or folder indicates that the item is ignored by synchronization.
• Resolution: correct the cause of the block (for example access permissions, an existing duplicate on kDrive Web, an exclusion parameter, or a placeholder status), then rename the item to remove _blacklisted if you want it to be synchronized again.

To avoid them:

• Check your access rights before creating or modifying files in shared spaces, organizational folders, or Common documents.
• Avoid duplicates when creating or moving files between your computer and kDrive Web.
• Do not uncheck a folder in the desktop application if you continue to add items to it locally.
• With Lite Sync, download the file completely before modifying it instead of working on a dehydrated placeholder.
