What is the POT file format?
A .pot file is a presentation template in the binary PowerPoint 97-2003 format. It stores slide masters, layout designs, theme colors, fonts, and background graphics without containing actual slide content. Double-clicking a .pot in Windows creates a new untitled presentation based on the template rather than opening the template for direct editing.
Structurally, .pot uses the OLE2 Compound File Binary Format (CFBF) - the same container as .PPT presentations, .doc Word documents, and .xls Excel workbooks - identified by the shared signature D0 CF 11 E0 A1 B1 1A E1 at offset 0. Inside the container, the PowerPoint Document stream holds records for the slide master, notes master, and design metadata, but no user-facing slide pages. This absence of slide pages is the structural distinction from a .ppt file.
The format is documented in Microsoft's [MS-PPT] open specification. Minor internal version differences exist between PPT v8 (Office 97), v9 (2000), v10 (XP/2002), and v11 (2003), all covered by [MS-PPT]. Optional encryption uses Office 97-2003 XOR or RC4 ciphers defined in [MS-OFFCRYPTO].
Modern PowerPoint reads and converts .pot files but saves new templates in the .POTX Open XML format introduced with Office 2007. A substantial inventory of pre-2007 corporate .pot templates remains in circulation, and all major office suites maintain compatibility.
Security & safety
RISK: MEDIUMPOT files use the OLE2 binary format, which can contain embedded OLE objects and, in very rare historical cases, macro code (though PowerPoint 97-2003 macros in PPT/POT are less common than in Word/Excel). Modern PowerPoint sandboxes these. The primary risk is social engineering via malicious embedded objects. Open POT files only from trusted sources. Convert to POTX to eliminate any legacy binary macro concerns.
