I think some are missing hardhat's point:
There is no logical way the website could be reading files stored on
his own computer when others are browsing the site (unless somehow his home
harddrive is mapped to the webserver - if so get Spybot fast.)
Three possibilities:
First, your FrontPage copy is not really stored on your own
harddrive but rather FP stored it on your ISP's system.
or Second, You opened the website "Live" in FP and are working
right on the webserver (which is "okay" but no backup)
or Third, Your browser is browsing local temp files on your
computer - not really online.
(If so - > Internet Options > Delete Temporary Internet Files)
Do this: (some varies with your version of FP)
1. Create a new empty folder in your computer's My Documents Folder
(and Maybe in My Webs if you have it)
2. Give it a name (Right click Rename)
3. Start FrontPage
4. Click > File > New then depending on your version or
configuration click New Web or New One Page web.
5. Navigate to that New Folder as the place you store your new blank
website and save your first page as index.htm (or html).
6. If after that it still looks like a folder you can right click
in FP and select " Convert to Web"
7. That file is now your dummy website.
8. If it asks you the location of your remote web site - give it the
url of your online website.
9. Otherwise, perhaps using the help instructions, find on your
version of FP where and how you publish and import websites.
It is different on all 3 versions I have of FP.
a. On FP 2003 I click a tab for Remote Website, make sure I have
it set to download (publish from Remote to local) (not upload the dummy file
to online) and it downloads.If it asks, yes overwrite the dummy index page.
b. On FP 2000 I select import website from the File menu, enter
the online url as the source, and point it to be saved in the New Folder in
My Documents\My Webs. If a wizard asks how many levels you want to import -
do them all or you will leave files behind - not that I imagine your website
is many levels deep..
10. From that point onward you can work on your local New Folder all
you want, and when it is perfect select Publish and it will zip up to your
online web for others to look.
On the other hand, you can continue to work on the website live -
and believe me the files you think are stored on your own computer really
are not.
