Carbonio Files provides a file storage system with ability for sharing documents with colleagues, collaborative editing, and document versioning.

Items saved in Carbonio Files are shown in the central area and are organised in a folder structure, which initially contain a number of pre-defined shortcut as icons: Home, Shared with me, Trash, Filters, and Uploads. Files can be arranged in folders under Home; a list of recent files and folders accessed by the user is also available, to allow to quickly resume work on these documents.

Working with Files#

The following panels summarise the most common activities that can be done on files and folders

File Upload and Download
  • To upload a file to Carbonio Files, either click the Upload button on the top bar, or drag and drop a file from a file browser to Carbonio Files

  • To download a file from Carbonio Files, right-click on it and select Download

While uploading new files, a badge shows the completed and total number of documents being uploaded.

Create new Folder and Files

To create a new item in Carbonio Files, use the right mouse button in the file list (central area) to create new folders, documents, spreadsheets, or presentations.


The following characters can not be used in folder’s name: Slash / Backslash \ Semicolon : Question Mark ? Plus sign + Asterisk * Percent sign %


When clicking once on a file or folder, an informative box appears on the right-hand side, which contains multiple tabs:


Shows a (partial) preview of the file, if the file belongs to a recognised type. There are also a number of metadata visible and a description of the file or folder can be added at the bottom.


Lists the owner of the file or folder and who has access to it. It is possible to allow access to internal collaborators or external user, with different modalities

  • Internal collaborators: you can add a a collaborator to a single file or an entire directory by writing the e-mail address, then click SHARE; otherwise, in the Collaboration Links section click GENERATE LINK to create a link that will allow anyone with the link to give either Read and Share or Write and Share permission on the file

  • External users. It is possible to share single files or folders with external, anonymous users. In the bottom Public Links section use the ADD LINK button to generate a link to allow access to everyone. Optionally, add a description and expiration date (defaults to the end of the current day) to the link, then click GENERATE LINK. Anyone who receives this link will be able to download the file or to browse the directory until the link expires or is revoked.

    In case of a shared directory, any change in it (e.g., a new file or subfolder has been added or removed) will be automatically reflected in the link. Moreover, being a public link, files can be individually downloaded, but a bulk download of the whole content is not possible.

The SHARE button is clickable for internal collaborators and only if the e-mail address is correct.


Sharing a folder implies that permissions are inherited by the whole hierarchy underneath, so all files and directories contained there will have the same access permissions.

Sharing with external users is limited to files only: no directory can be shared. To allow an external user to access a file,

Versioning (files only)

The history of each file is preserved in case the file is edited or a new version is uploaded. Manual removal of unused or deprecated versions of a file is possible.

By default, five version can be stored for each file. Editing a file that has reached this limit is prevented, with an error message informing of the reached limit. This limit can be customised and even removed, by configuring it to -1.
