The SLDS file extension belongs to an old slide-file format used by Microsoft PowerPoint 2 for Mac, Microsoft's presentation software. An SLDS file contains the text, graphics, and other slide content created for a PowerPoint presentation.
The format is associated with the Mac version of PowerPoint and is not a standard format for current presentations. Later versions of PowerPoint use other file types, including the sldx file extension for individual slide files.
SLDS is a historical format and is no longer commonly used. Current versions of Microsoft Office for Mac and Microsoft PowerPoint for Windows may not open it directly, depending on their legacy-format support.
To open an SLDS file, use Microsoft PowerPoint 2 for Mac or a later compatible version of PowerPoint that supports importing this legacy format. Because the format is obsolete, current versions of PowerPoint may not recognize it.
If the file does not open, an older supported copy of PowerPoint may be required before the slide can be saved in a current presentation format.
If a compatible version of Microsoft PowerPoint opens the file, use its save or export command to create a current PowerPoint presentation file.
When direct conversion is unavailable, the file must first be opened with a version of PowerPoint that supports the old format.
