    In PowerPoint 2002 (but not in earlier versions) you can protect presentations with a password for editing.

    There is a third-party product PrezGuard for protecting presentations from http://www.aladat.com that was mentioned in an earlier <!post=post, 84735>post<!/post>.

    Re: Protect PP files from editing (Power Point 200

    You can use the free PowerPoint Converter at the same site (aladat) to achieve the protection. The difference is that the slides truly cannot be edited. You must keep a copy of the originals if any changes are to be made.

    Now that I think on it, there is a way to do this with only PPTs capabilities. I gather XP has always had it but MS released an Album Wizard for PPT 2000 recently. It automatically pulls a set of graphics files into a presentation, properly stretched and located on the slides. So, use the SaveAs function to save a presentation as JPGs and then pull them back in with the Album Wizard. Voila, an uneditable presentation. Unfortunately, the JPGs tend to artifact a bit. I'm hoping someone can tell me how to control PPTs JPG compression to limit that. But otherwise, it should work fine.

    I haven't used the album thing, but if you export as PNG, I think you will find the quality much better than JPG or GIF. Needless to say, you won't get the same compression.

    True. The last PPT presentation I worked with was approx 300K native, 400K JPG, 600K WMF, 1.4M GIF, and 2.5M PNG.

    I guess I could export as PNG, convert to JPG using Irfanview, and reimport those. Both WMF and GIF look bad with true graphic backgrounds. With JPG, the graphics look good and the lettering is OK but the artifacting around the lettering is distracting.

    You can also try saving the file as a PowerPoint Show (.pps), which makes it difficult for the novice to open and edit the show. It only opens in the slide show mode when they launch it.

    I think I embedded a .pps in an Excel spreadsheet once and password protected that, which made it even more difficult.

    But even password protection can be cracked if they want in your presentation badly enough. The actions you take to protect it depend on how malicious the recipient might be. <img src=/S/devil.gif border=0 alt=devil width=15 height=15>

    Hi,
    Thanx all for the many suggetions,
    Though responsibility lies with the user not to edit PPT files its a human tendancy to edit when editing is allowed.
    All the above disscussions enable us to come to conclusion that prior to PP2002 protection of PPT files are not inbuilt feature of PPT.

    You are correct. Version 2002 is the first PowerPoint to feature password protection. It was a thing we screamed for and begged for thoughout all the previous versions. But we have it now and it is one of many good reasons for users to upgrade, IMHO.

    Will your recipients also have version 2002?
