and save it with a slightly different name. That would be easier then trying to delete all those blank pages.

As to why it happened- I hate to say it but stuff happens- I've had unaccountable options change. It is annoying. Fortunatly you didn't lose you pages they were just mixed up with a lot of blank pages.

Most modern ones automatically save versions of the file as you work on it. You might have a copy stored somewhere under a cryptic name.

Knowing which word processor and the version, maybe you or I could google where it would store those backups.

For instance I found this:

I'll call my computer guy. He should know. He's been our computer repair/replace/advisor for years and years now. Maybe it is time for an upgrade.

You can find out the Word version by going to the little Microsoft button at the upper left, click it, then in the drop down menu click Resources/About. (At least that is where I can find out my Word 2007 version info.)

Apparently Word has changed and no longer uses cryptic titles for their auto save versions. It does still have an autosave feature which can be selected in the Word options (at the bottom of the popup when you click the Microsoft icon at the upper left) under Advanced - scroll down to Save. The location can be selected in the same window under General/File Locations - default for AutoRecover files is Users/(yourname)/AppData/Roaming/Microsoft/Word.

That all seems to be selected by default since I have never used Word much I haven't bothered to customize it. But since I have not used it much, I don't have any autosaved documents in my AutoRecover folder.
