Working with files (incl. links)

Files from the "outside", i.e. from your own computer or other online data storage services, can be integrated into Stackfield with a specific format/layout. This includes file types such as Word, Excel, PDF, image (JPG, PNG, etc.), and links. Using our search functions, you can easily find the title / name of a file.

Alternative directly in Stackfield: Pages and Whiteboards

Note: Individual functions / modules may not be available / renamed due to settings of the organization, the room and/or your assigned right group (see: Options for admins)!

Uploading / attaching a file and storage location


You can upload files in the modules Files and Communication, and attach them to all entries of the room. Simply click on the plus button / paperclip icon and select the corresponding source.

Files located on the computer can be stored easily via drag and drop. The directory structure is maintained during the process, i.e. folders that are uploaded to Stackfield via drag and drop will also be stored as folders.

Folder drag & drop
Folders can be uploaded via drag and drop

All uploaded files are stored with the format defined for the file type. By default, they can be found and opened in the files module.

If a file already exists with the same name (the file extension must be identical as well) as the file you're uploading, a dialog box appears. You can then either replace the old file with a new version or rename the file to be uploaded. Alternatively, you can cancel the process by pressing "X". If one of the components of the name is different, the file will be uploaded directly as a new file, since no assignment to previous files is possible.

If you are uploading multiple files at once, the upload process will not be aborted for the other files.

  • If you only want to copy the content of a file, the formatting will depend on the way you paste it. Click here, to learn more about formatting in Stackfield.
  • You do not need to cache screenshots to upload them to Stackfield. Just select the option "Copy" within the screenshot (Ctrl or Cmd + C) and paste it with Ctrl or Cmd + V at the desired location.
  • E-mails (as msg.-file) or file attachments from emails can be moved to Stackfield via drag & drop, the contents in the email program will be preserved. (Exception: With Firefox it is not possible in a direct way, but the contents can be transferred via an intermediate step on the desktop.)
    Alternative: Email integration

Within the module Communication

To create a file within the communication module, simply click the plus icon to the left of the text input field and select the option "File".

Click here, to learn more about attaching files on Stackfield.

As a link

Files from external services (criterion: accessibility via HTTP or HTTPS), such as Google Drive and Dropbox, are uploaded to Stackfield as links.
Click here, to learn more about links in Stackfield.

Through email integration

Email integrations create automatic forwardings of emails to rooms in the form of tasks, discussions, and chat messages. Files attached to these emails will also be attached to the task / discussion or, in the case of chat messages, created loosely within the chat history.

How to organize the display

Files are displayed in the form of a list for all authorized users. By default, only the title and file type are displayed. However, additional information (e.g. labels and size) can be displayed via the "MORE" button in the overview or in the filter under "Columns". You can also create folders for the structured storage of files.

The filter allows you to modify and save the view according to your own requirements. Occasionally the view must be updated (see: Notifications within a room).

Preview of files directly within Stackfield

All plans offer organizations the 1-picture preview for image files, PDF*, MP4, and links in the communication stream of rooms / direct messages with deactivated end-to-end encryption. Starting from the Premium plan, preview for (Open/Libre) Office files is additionally possible. The corresponding Office application does not need to be installed for a preview.

*Tip: Via mouseover on the 1-picture preview of PDF files the number of pages can be shown.

Procedure: Browser / Desktop App

To open the preview of a file, click on the preview image or the option "Preview" next to the corresponding file within the files or communication module.

Preview of files

Click on the image or "Preview" to display it

Now, you can zoom in (magnifying glass symbol with a "+"), zoom out (magnifying glass symbol with a "-") or display the file in its original size (symbol: diagonal arrow) via the application bar in the upper right corner. A thumbnail view of all pages on the left allows you to quickly "jump" to the corresponding page. To view all document pages, simply scroll down / up.

Preview Office documents
Preview of Office documents

Note: The preview of MP4 files (thumbnail view of videos) is possible within the communication stream. However, the preview must not be blocked by browser settings (plug-ins), system settings, or any software installed on the device. For links, the technical requirements of the provider (e.g. YouTube) must be met on top of that.

Procedure: Mobile App

Within the mobile app, you can open the preview of a file by clicking the preview image or by clicking "Preview" within the opened file. For PDF files, there is currently only the 1-image preview available on Stackfield. You need to download the file to view it in full. On Apple devices, a preview of the file can be opened without saving it to the device. Extensions to this are forthcoming.

Downloading and editing files


  • You want to map a concrete workflow, i.e. who should do what and when? Work with tasks and attach or link the corresponding file(s) (see: Attachments).
  • There are several users working on the same file? Mark the editing state with a label and/or use local editing including automatic marking of the state (visible within the browser and the desktop app).

Procedure: Browser / Desktop App

You can download files within the overview of the module Files as well as in its opened state and save them on your computer. To download a file within the overview, click on the More button (symbol: three dots; visible by mouseover) and select the option "Download". To download an already opened file, click on the download icon in the upper right corner. Afterward, you can open, edit and save the desired file at the respective location. Finally, you need to upload the new version back to Stackfield.

It is also possible to download multiple files at once (procedure).

Local editing

Attention: Local editing of individual files is only possible within the desktop app.

All plans offer at least the local editing of (Open/Libre) Office files. You can download the desired file via the "Edit locally" button (visible by moseover).

Start local editing
Start editing via the "Edit locally" button

The file will then open for editing directly outside of Stackfield. Within the room and within My Week, the change of the button to "Locally in work" will automatically indicate a note regarding the editing status. All files that are being worked on locally can also be viewed within the Reports as well as via the filters. This way, your team can quickly identify who is currently working on a new version in the various workspaces without having to assign a label or status manually.

When you are done editing the file, save it. ("Save" is perfectly sufficient. "Save as", along with the associated selection of a location on the computer is not necessary.)

Afterward, you can upload the new version to Stackfield or cancel the editing. Within the overview in the room / within My Week, you can select the options by clicking the "Locally in work" / "Actions" button. Within an opened file, you can upload the file by clicking the upload button in the upper right corner.

To edit the file, you need to open the file in the storage location of your mobile device (varies depending on the file manager app you are using). On Android devices, the file is automatically stored in the specified download folder (e. g. "My Files" app). On iOS devices, a popup opens in which you can select the desired storage location. You also can open a complete preview of the document via the option "Quick Look" here.

How does the versioning of files work?

Any file already in the room can be updated to the latest version by uploading it again under the same name (+ same file format*) within the same location (room + folder inside the room) and using the "Upload new version" option. Within the opened file, a button in the upper right corner allows you to do so as well.

Upload new file
Upload a new file

*Note: If the users use different Office formats (MS Office vs Open / Libre Office):
Versioning is only possible if the user is working in/with the same file and does not switch to one's own format. If the formats differ, a new file is uploaded instead of a new version.

Once a new version has been uploaded, a note is added to the comments section. The version number is displayed in the upper left corner. Clicking on it opens a list with all versions. This way, you can easily select and view any desired version.

Switch between versions
Switch between different versions

Within the overview, you can view older versions via "Download" or "Preview", current versions additionally via "Edit locally".

To remove the last version, click the more button (icon: three dots) in the upper right corner of the opened file and select the option "Delete Latest Version "*.

*Note: By selecting the option "Delete", the file will be deleted with all its versions.

Comments on the file and markers within the image

Basis: Working with the communication module and the comment area
- Here you will also find information about the history.

The comment area can be displayed within an opened file by clicking the speech bubble icon in the upper right corner. Comments, mentions to users or references / links / attachments can be left there (see: Message options). All changes are visible in the history.

Special feature for files: Marker within the image (->Annotations)

Within files, you can leave annotations directly in the image at the point you want to clarify. Just click on the pencil icon in the upper right corner of the opened file and select the position of the annotation. Now, you can comment on the annotation and create it via Enter. The annotation will be displayed immediately by a red circle with numbering. As soon as the annotation is clarified / considered, it can be checked off. Checked off annotations are displayed in green unless they are hidden in the history.

Available file types for preview and local editing

The following file types are available by default for preview and local editing:

  • Word processing (MS Office / OpenOffice): .docx; .doc; .odt
  • Spreadsheet (MS Office / OpenOffice): .xlsx; .xls; .ods
  • Presentation creation (MS Office / OpenOffice): .pptx; .ppt; .odp

Starting from the Premium plan, an extension of the file types is possible for local editing.

Preview of Office files

Preview for Word, Excel, and PowerPoint is available from the Premium plan.

Within the tab Settings in the organization settings you can define whether the preview should be available for Office files from end-to-end encrypted* rooms. If it is deactivated (default setting), a note will appear whenever a request is made stating that the preview is not available.

File preview for end-to-end encrypted rooms
Organization settings: Preview of end-to-end encrypted Office files

*What happens when accessing a file from an end-to-end encrypted room?

All files originating from end-to-end encrypted rooms are stored encrypted on Stackfield's servers. Stackfield has no access to the encryption keys of these files.

The preview of a file must be created on Stackfield's servers. For this purpose, an individual encryption key of the file is sent only once to Stackfield's servers, the file will be decrypted and the preview will be created, which can then be displayed to the user.

Once the preview is closed, the information is deleted from the cache again. The file then remains end-to-end encrypted, inaccessible to third-party access, and secured on Stackfield's servers. The content from the preview is not saved by Stackfield.
