With automatic indexing turned on, the folders and files you upload are assigned a sequential number that corresponds to their upload queue.

Later, if necessary, you can move the files and folders around within the structure by either renaming them from the context menu or drag-and-dropping them to the necessary position in the structure.

To eliminate gaps after deleting or moving documents, use the Rebuild index option to regain sequential numbering. Rebuilding index works folder by folder as well as for the parent folder, i.e. entire project structure.

To update the index, click Rebuild index on the top panel.

Once selected, modal will ask you to confirm.

This action, once confirmed, cannot be undone.
