.POT file extension

To open .POT files on Windows, right-click the .POT file → Open with → choose Microsoft PowerPoint if it appears to be a presentation template (legacy PowerPoint format).

To open a .POT file, first identify whether it is a PowerPoint template (presentation-related) or a gettext translation template (text-based). PowerPoint templates open in Microsoft PowerPoint-compatible apps, while gettext .pot files open in a text editor or gettext/translation tools.

What “reviewed” means on this page

Format fit: whether the “what is this file?” description matches common real-world use of the extension, including category, typical MIME types, and aliases.
Opening paths: whether Windows / macOS / Linux steps read plausibly for current OS dialogs and default apps; we remove fantasy menus and unsafe shortcuts.
Security framing: whether risk notes match the extension class (for example executables vs plain data) and whether affiliate wording does not contradict the security section.
Sources and further reading: whether external links point to vendors, standards bodies, or other primary references where possible; we avoid inventing details we cannot ground.
Limits: this is clarity and safety-messaging QA, not a guarantee that every statement is exhaustive or that every binary you download is harmless.

How to open .POT files

Use these platform-specific instructions to open .POT files safely.

Windows

Right-click the .POT file → Open with → choose Microsoft PowerPoint if it appears to be a presentation template (legacy PowerPoint format).
If it seems text-based (e.g., contains msgid/msgstr), open it with a text editor and/or gettext-related translation tooling.

Full Windows guide

Mac

Control-click the .POT file → Open With → choose Microsoft PowerPoint (or another PowerPoint-compatible app) if it is a presentation template.
If it is a gettext template, open it in a text editor and treat it as a localization template file.

Full Mac guide

Linux

In your file manager, use Open With; Linux desktops typically rely on shared-mime-info mappings, so the file may be recognized as either a PowerPoint template or a text-based gettext template depending on content.
If it is a gettext .pot, open it with a text editor; if it is a PowerPoint template, you may need a PowerPoint-compatible office suite installed to view/use it.

Full Linux guide

iOS

If it is a PowerPoint template, try opening it in a PowerPoint-compatible iOS app; if it does not open, transfer the file to a desktop PowerPoint-compatible app.
If it is a gettext .pot, iOS is typically not a great environment for translation workflows—open it as plain text in a text editor app or transfer to a desktop.

Full iOS guide

Android

If it is a PowerPoint template, try a PowerPoint-compatible Android app; if it fails, open it on a desktop PowerPoint-compatible app.
If it is a gettext .pot, open it in a text editor app (plain text) or transfer to a desktop for proper localization tooling.

Security notes

Treat PowerPoint .POT files as potentially risky when sourced from untrusted senders: legacy Office binary formats can be abused via malicious content or parser vulnerabilities, so prefer opening them in up-to-date software.
If you receive a .POT unexpectedly (especially via email), confirm whether it is meant to be a PowerPoint template or a gettext localization template before opening it with an Office app.
Gettext .pot files are plain text templates; they are generally safer to view in a text editor, but avoid blindly running build or automation scripts you received alongside them without reviewing what they do.

If you did not expect this file

This extension is usually plain data, text, or structured content—not a program by itself. The practical risk is social engineering (a scam attachment or misleading filename). For trusted senders you rarely need heavy-handed antivirus wording; use these tools when you want an extra check on unexpected downloads.

Avast

Avast offers free and premium antivirus software that protects against viruses, malware, ransomware, and phishing. Scan files before opening them to ensure safety.

Norton

Norton 360 delivers comprehensive antivirus protection, VPN, and identity theft monitoring. Scan files for threats before opening to keep your device secure.

Can't open this file?

These are the most common causes and fixes when .POT files fail to open.

Common reasons

The .POT file opens as gibberish or unreadable text
PowerPoint says it cannot open the template or the file is corrupted
The file type is misidentified (.POT could be PowerPoint or gettext)
Linux desktop does not show the right icon/app for .POT

Fix steps

If the file came from a presentation workflow, open it in Microsoft PowerPoint (or a PowerPoint-compatible office app) instead of a text editor.
If you expected a gettext .pot, check that it contains gettext entries (e.g., msgid/msgstr). If not, ask the sender what created the file.

OS-specific troubleshooting

What is a .POT file?

.POT is an ambiguous extension most often associated with legacy PowerPoint 97–2003 templates that use the same underlying binary format family as .PPT (per the MS-PPT specification). In software localization workflows, .pot also commonly means a GNU gettext Portable Object Template: a text template generated from source strings (e.g., by xgettext) used to create or update translations.

Background

In Microsoft Office workflows, a .POT file is typically a PowerPoint 97–2003 template. This template format is part of the legacy PowerPoint binary file format family documented by the Library of Congress and the official Microsoft [MS-PPT] specification. Templates are used to create new presentations with pre-defined layouts, styles, and placeholders.

In software development and localization, .pot is widely used by GNU gettext as the "PO template" (Portable Object Template). It is generated from application source code (commonly by xgettext) and serves as the base file translators use to produce language-specific .po files.

Because the same .pot extension is used in these two very different workflows, the most practical first step is to infer the type from context: a PowerPoint .POT is typically larger and comes from presentation work; a gettext .pot is plain text and often contains gettext headers and message entries (msgid/msgstr).

Common MIME types: text/plain

Common .POT issues

The .POT file opens as gibberish or unreadable text

This usually happens when you open a PowerPoint .POT (binary legacy format) in a text editor, or when the file is not actually a gettext template.

If the file came from a presentation workflow, open it in Microsoft PowerPoint (or a PowerPoint-compatible office app) instead of a text editor.
If you expected a gettext .pot, check that it contains gettext entries (e.g., msgid/msgstr). If not, ask the sender what created the file.

PowerPoint says it cannot open the template or the file is corrupted

Legacy PowerPoint template files are binary and can be damaged by partial downloads, email gateways, or incorrect file transfers.

Re-download or re-copy the file from the original source (avoid copy/paste through chat tools that may alter files).
Try opening it on another machine/app to rule out an installation-specific issue.
If you have access to the original author, ask them to re-export or resend the template.

The file type is misidentified (.POT could be PowerPoint or gettext)

The same extension is used for two unrelated formats; the correct app depends on what the file actually contains.

Check the origin: presentation/template libraries usually mean PowerPoint; developer/localization repositories usually mean gettext.
Inspect a copy with a text editor: gettext .pot is readable plain text with msgid entries; PowerPoint .POT is binary and will not be readable.

Linux desktop does not show the right icon/app for .POT

On Linux, file associations are commonly driven by the shared MIME database and desktop settings; ambiguous extensions can lead to the wrong default app.

Use Open With to pick the correct app (office suite for PowerPoint templates; text editor/translation tooling for gettext templates).
If needed, adjust your desktop’s file association for .pot, keeping in mind it may be used for two different formats.

FAQ

Is a .POT file a PowerPoint file?

Often, yes: .POT commonly refers to a PowerPoint 97–2003 template (legacy binary format). But in software localization, .pot also commonly means a GNU gettext Portable Object Template (plain text).

How can I tell whether my .POT is PowerPoint or gettext?

If opening a copy in a text editor shows readable entries like msgid/msgstr, it is likely a gettext template. If it looks like binary/unreadable characters and comes from a presentation context, it is likely a legacy PowerPoint template.

Can I convert a .POT to .PPTX by renaming it?

No. Renaming only changes the extension label. Use the appropriate application to open the file and then use its Save As/Export features if you need another format.

Does .POT have a single official MIME type?

Not reliably as a single answer, because .pot is used by different formats. MIME types are registered through IANA, and platforms may also rely on shared MIME databases; the correct identification depends on whether the file is a legacy PowerPoint template or a gettext PO template.
