Ventura Publisher was a desktop publication software package original built on the GEM VDI Metafile system by Digital Research. Distributed by Xerox until bought by Corel in 1993.
Ventura Publisher versions 3-5 save its documents to the .CHP (Chapters) format, but also uses the following components:
|Frame tags file||FRM|
|HPGL converter settings||PRF|
|OLE object file||VPO|
Versions 7-10 use .VP to store the full publication including stylesheets and chapters. .VP is based on the Microsoft Compound File format.
Corel VENTURA versions 3 to 5 save stylesheets externally with the filename extension STY. Versions later than version 5 save the stylesheet as part of the publication file. If you are importing tags from version 3 to version 5 publications, open the stylesheet file. If you are importing tags from a version later than version 5, open the publication file. Frame tags in versions 4 and 5 publications are stored in a chapter file with the filename extension CHP.
