Opening Password Protected File

[Ian Stock]

We have a file at work that is password protected and we can not open, even
with what everyone believes is the correct password. (We could open the
file a few weeks ago with the password.) The file is not linked
to any other file.

Any suggestions on what we should be looking for to try to open the file?

Ian,

Possibly someone changed it unknowingly???
The workbook open password is the hardest to crack.
A copy of a post by Norman Harker (attached below)
should point you to some resources.

Hi!

If it is a workbook password then here is the standard post on that one:

The following sites advertise ability to recover, amongst other things,
Excel file passwords. These passwords are imposed when saving Excel
files
and are not to be confused with *internal* passwords on sheets and
workbook
structure.

http://www.intertek.org.uk/
Excel Workbook recovery. Demo version up to 2 characters free. Full
version
for $5 advertises ability to recover any password.

Elcomsoft Advanced Office XP Password Recovery
http://www.elcomsoft.com/aoxppr.html
Unregistered (trial) version can be used during 30 days after
installation
(although it doesn't expire, actually) and has some limitations. They
have
programs for earlier versions. Cost of license $30. Reported to take a
long
time but worked in finding a 12 character lower case password. Like most

brute force approaches the fastest CPU speed computer available should
be
used.

Lostpassword.Com
http://www.lostpassword.com/excel.htm
All versions of MS Excel are supported (including Excel 2002) $45.
Download
demo version covers 2 character passwords and works but not much use.
