How to open .POTM files on Windows

To open .POTM files on Windows, right-click the .potm file and choose Open with → Microsoft PowerPoint (or double-click if PowerPoint is the default).

Step-by-step instructions

  1. Right-click the .potm file and choose Open with → Microsoft PowerPoint (or double-click if PowerPoint is the default).
  2. If a security prompt appears, choose whether to enable macros only if you trust the source; otherwise keep macros disabled.

Common issues

Macros are blocked or the file opens with a security warning

.potm files can contain VBA macro code, so PowerPoint may open them with macros disabled or show a security warning to reduce the risk of running untrusted code.

  1. If you do not fully trust the source, keep macros disabled and only use the template’s non-macro content.
  2. If you trust the source and require the automation, open the file in Microsoft PowerPoint and enable macros only when prompted and necessary for your workflow.

Opens as a template rather than a normal presentation

.potm is a template format; it is meant to be used to create new presentations rather than edited as the primary deliverable.

  1. In PowerPoint, use the template to create a new presentation (a new file based on the template).
  2. Save the new presentation as a standard presentation format (for example, a non-template presentation type) if you intend to distribute it as a slide deck rather than a reusable template.

Doesn’t open correctly in non-Microsoft apps or loses macro functionality

.potm is OOXML-based and macro-enabled; apps that partially support OOXML may display slides but not preserve VBA macros or all template behaviors.

  1. Open the file in Microsoft PowerPoint for the highest compatibility, especially if the template relies on macros.
  2. If you need cross-app sharing, consider distributing a macro-free template format instead (macro-enabled features are specific and may not be supported elsewhere).

Security note

.potm can contain VBA macros; enabling macros can execute code, so treat .potm files from email or unknown sources as potentially unsafe.
