- * Welcome to MFI "Makes Files Invisible"
-
- Version 1.1 1/25/96
-
- You can always find the latest versions of all our software on the
- Internet at: www.pc-magic.com
-
- MFI keeps your private files private by making them invisible to
- unauthorized users. To those without your password your invisible
- files might as well not exist. They don't show up in directory
- listing and programs, applications, utilities, file managers, DOS and
- Windows can't find, view, delete, modify, use, or work on them. For
- all practical purposes your invisible files simply don't exist.
-
- But enter your password and instantly all your invisible files become
- visible and accessible. You don't have to un-hide each individual
- file when you want to access it because MFI takes care of everything
- automatically and transparently. It's so simple! Those with your
- password have instant, complete and normal access to all your
- invisible files, those without won't even know they're there.
-
- If you share your computer with others then you need MFI. Use it to
- protect those files you don't want others to corrupt, view, delete,
- use or modify.
-
- MFI will works in DOS, Windows 3.1, and Windows 95. It will not hide
- your files in OS/2, 32 bit file access in Windows for Workgroups or
- Windows NT. It is not for use on shared LAN drives.
-

-
- * Installation
-
- If you haven't already installed MFI you need to do so now. Run
- "INSTALL.EXE" from within Windows.
-
- * Disk compression software
-
- If you have disk compression software like Stacker or DoubleDisk make
- sure that the line in your AUTOEXEC.BAT file that runs MFI (or
- whatever you renamed it during installation) occurs AFTER the line
- that loads your disk compression program.
-
-
- * Making MFI tougher to defeat
-
- MFI does a great job of keeping your files invisible if it's loaded
- and running. If no one knows MFI is running then they won't have any
- reason to try to defeat it. To the non-authorized user, MFI is
- totally transparent. If we broadcast the fact MFI is protecting your
- files then a nosey user could disable it by removing the line in the
- AUTOEXEC.BAT file that runs MFI.
-
- There are things you can do to make MFI very difficult to defeat.
- During installation MFI.EXE is renamed to the new name you give it.
- You can make multiple copies of this renamed file, giving each copy a
- different name, putting them in different directories, and running
- each of the different copies from within your AUTOEXEC.BAT file.
- Someone would then have to remove all references to the renamed
- MFI.EXE files in the AUTOEXEC.BAT file before MFI would be defeated.
- Don't worry about loading MFI multiple times as it only loads itself
- once regardless of how many times it is run.
-
- If you are using Windows 95 you can also modify the SYSTEM.INI file
- to run MFI in case the AUTOEXEC.BAT file doesn't. Look for the
- section "[386Enh]" and add a line underneath it that says "device="
- followed by the full pathname of the renamed MFI.EXE file. For
- example, if during installation you rename MFI to SYS_MGR, and the MFI
- files are in C:\MFI, then you would add the line:
- "device=c:\mfi\sys_mgr.exe".
-
- If you decide to load MFI multiple times from within your
- AUTOEXEC.BAT file keep in mind that using the "MFI Utilities" to
- change your password only changes the initial copy of MFI. You have
- to manually copy that file into the other files. Likewise using the
- "MFI Utilities" to un-install MFI only un-installs the initial copy
- of MFI. You'll need to manually remove all other references to the
- renamed MFI file in your AUTOEXEC.BAT file (and SYSTEM.INI if
- appropriate).
-
- * P-Files
-
- P-Files (Private Files) are those files you want to be invisible to
- unauthorized users. You designate which files you want to be P-files
- by selecting the "Designate P-Files" button in the MFI utilities
- program.
-
- * Making P-files Invisible
-
- Your P-files are invisible from the time you start your computer
- until the time your computer is turned off unless you deliberately
- make them visible as explained below.
-
- * Making P-files Visible
-
- To make your P-files visible go into the MFI utilities in the
- Accessories group (you'll need to enter your password) and then
- select "Make P-files Visible". This gives you instant, complete, and
- normal access to all your files, including your P-files.
-
- To make your P-files invisible again just return to the MFI utilities
- (you won't have to enter your password this time as you've already
- been granted access as an authorized user) and select "Make P-files
- Invisible". The P-files also become invisible again if your re-boot
- or turn off your computer.
-
-
- * Other MFI Utility Functions
-
- In addition to designating P-files and making them visible or
- invisible, the MFI Utilities program in the Accessories Group also
- lets you register MFI, change passwords, read this documentation,
- install new versions and un-install MFI. Each of these
- functions is self-explanatory.
-
- * WARNING
-
- Some not-so-bright disk fix and defragmenting utilities, while
- perfectly safe if used when P-files are visible, can become confused
- when P-files are invisible. Their confusion can result in deletion
- of your P-files.
-
- To prevent this from happening you should designate all your disk fix
- and defragmenting utilities as P-files so that they can only be run
- when P-files are visible.
-
- CHKDSK.EXE is the only program we've tested that becomes confused
- (and only if run with the /F command line switch), so we've taken the
- liberty of designating it as a P-file. The versions of SCANDISK and
- DEFRAG that come with Windows 95 DO NOT get confused and therefore
- need not be designated as P-files. However, because we've tested no
- others, all other disk fix and defragmenting utilities SHOULD be
- designated as P-files, just in case.
-
- If you want, you can test your disk fix and defrag utilities to see
- if they'll be a problem. Just run them with P-files hidden and P-
- files not hidden. DON'T FIX ANY ERRORS THAT TURN UP!!! If you get
- more errors when P-files are hidden then that utility should be
- designated as a P-file so it can only be run when P-files are
- visible. If the errors are the same when P-files are hidden as they
- are when P-files are visible then the utility need not be designated
- as a P-file.
-
- For those of you interested in the technical details, this is why
- CHKDSK (and maybe others) gets confused. These utilities bypass the
- operating system and directly examine your disk. In this way they
- can see the space allocated for your invisible files. Instead of
- directly examining the disk to see which files belong to this
- allocated space (as smart utilities do) they instead ask the
- operating system. Since the operating system doesn't see your P-
- files when they're invisible these utilities assume the space
- allocated to your invisible files should be freed, thereby deleting
- the invisible files on that drive. On the other hand these utilities
- work fine when P-files are visible, because the operating system then
- sees your P-files. So as we said before, designating these utilities
- as P-files (thereby allowing them to run only when P-files are
- visible) completely eliminates the problem.
-
-
- * Things to keep in mind
-
- IMPORTANT: Don't designate HUTIL.EXE or MFI.EXE (which you renamed
- during installation) as P-files or you won't be able to run them when
- your p-files are invisible.
-
- Backups: It's best to make P-files Visible when making backups,
- otherwise your P-files won't get backed up.
-
- Copying P-files: Almost always when P-files are visible you can work
- on them just as if they were normal files, without worrying about
- whether they're P-files or not. However, when you use the DOS "copy"
- command to make a copy of a P-file, the new file is NOT designated as
- a P-file. Therefore if you copy a P-file, make sure you designate
- the new copy as a P-file by using the "Designate P-files" function in
- the MFI utilities. Don't worry about the original file as it remains
- a P-file.
-
- Other P-files: "MFI Utilities" may indicate that there are P-files
- which you didn't designate as such. Leave these files alone. They
- may be files other programs need to operate correctly.
-
- All or nothing: As you may have noticed, MFI is an all or nothing
- thing. You can't specify different levels of access. Those with the
- password have access to all your P-files, those without don't. It's
- as simple as that.
-
- Networks: Do not use MFI on a file server for a LAN. You may
- however use it to protect files that exist only on your workstation's
- drives.
-
-
- * Problems?
-
- "I'm having problems with Norton 95"
-
- Disable "System Doctor" during installation. You can enable it again
- after Magic Folders is installed.
-
-
- "I'm having problems with my disk compression software"
-
- Check your AUTOEXEC.BAT file and make sure the line that run MFI (or
- whatever you renamed it during installation) is being run AFTER the
- line that loads your disk compression software (Stacker, DoubleDisk,
- etc..).
-
-
- "I forgot my password. What now?"
-
- You'll need to un-install MFI and re-install it again.
-
- Follow these steps exactly:
-
- > Remove the statement from your AUTOEXEC.BAT file that runs MFI
- (remember, of course that you renamed it during installation).
- Note the full pathname of the MFI file.
-
- > If you manually modified the AUTOEXEC.BAT and or SYSTEM.INI files
- to make MFI harder to defeat then remove all references to the
- renamed MFI file from those files.
-
- > Go to where the MFI file is located and extract MFI.ZIP. Overwrite
- any existing files.
-
- > Re-boot the computer.
-
- > From within Windows run INSTALL.EXE in the directory where you
- extracted MFI.ZIP
-
-
- "I want to un-install MFI but I forgot my password so I can't use the
- MFI utilities to un-install. What now?"
-
- > Remove the statement from your AUTOEXEC.BAT file that runs MFI
- (remember, of course that you renamed it during installation).
- Note the full pathname of the MFI file.
-
- > If you manually modified the AUTOEXEC.BAT and or SYSTEM.INI files
- to make MFI harder to defeat then remove all references to the
- renamed MFI file from those files too.
-
- > Exit Windows and re-boot.
-
- > Use any file manager to remove the System attributes from all your
- P-files. Don't forget CHKDSK.EXE which will probably be in your
- \DOS directory.
