OLE2 vs. XML Based Format
PagePlus X3 uses a new XML based format, enabling PagePlus versions from X3 onwards to open documents made in later versions.
Compressed Internal Objects
Some objects inside the PPP OLE2 file may be compressed. In version 9.03 for example, the file titled 'contents' is compressed, with the following file header suggesting this:
20 00 00 80 43 6F 6D 70 72 65 73 73 69 6F 6E 46 69 6C 65 00 EE 11 00 00 79 47 00 00 02 00 02 00
Which translates to:
...€CompressionFile.î...yG......
The existence of these compressed objects makes it difficult to penetrate the file type to retrieve information such as the user content. This may be considered a preservation risk without further information from a specification or a reverse engineering exercise.
