Mac 101: Don't move those files!

No, this won't be another post where I explain my reasons for loving and ordering the MacBook Air. That will come later when I actually have the MBA in my hands. Until then, I want to pass along a little bit of knowledge I learned while doing Mac consulting many moons ago: many files and folders on your Mac should be left alone and not moved or thrown away.

One particular incident that illustrates this point happened to a user who called me one day saying his entire Microsoft Entourage store of emails, contacts, etc. had just "disappeared" and Entourage had "reset to when it was new." Well, naturally that sounded a bit odd to me so I went over to see what I could do to resolve this little problem.

After a bit of searching around I discovered the user had "accidentally" moved a very important folder out of a folder called "Documents" (which is located in his individual "Users" folder) to the Trash. For the win, can you guess which folder he threw in the trash? iI you guessed it was his "Microsoft User Data" folder, you would be correct.

Fortunately for this particular user, after moving the folder back where it belonged all was well with Entourage and his data was restored. Let's go over that again, just to be clear. This particular folder, the "Microsoft User Data" folder, is located in your particular "Documents" folder on the hard drive of your computer.
So, if your user name is "john" for example, then your "Documents" folder is located inside the "john" folder inside the "Users" folder on the main level of your Mac's hard drive. Microsoft Office, like many other programs, stores important data in your individual user folder. Due to the way OS X works, you have full access to your individual user folder and can pretty much move or throw away anything you want.

However, don't do it. Unless it is a file or folder you know for sure you actually created yourself, leave it alone. Folders with names like "Microsoft User Data", "Library", "Application Support," etc. are placed where they are for a reason and if you mess with them or move them somewhere else, like to the Trash, you might be in for some real problems.

While we're on the subject of moving files and folders, OS X also has a certain way in which it likes many of its other default folders and files to be. Folders with names like "Applications", "System", "Library" and "Users" need to stay exactly where OS X puts them and should not be moved. Also, when you install Applications they usually get put into the "Applications" folder automatically so leave them there. In other words, let OS X put things where it wants and don't try to interfere -- it knows best.

There are, of course, some exceptions to this structure and if you know what you're doing you can often feel more free to make changes. But for most users, leaving things where they are is the best way to go. Sure, you might get lucky and not do too much damage by moving a folder or installing something somewhere other than "Applications", but then again you might run into issues and have to spend time figuring out what's wrong with your Mac instead of actually using it. And really, who wants to do that?

Once I decided to rename my user folder in the sidebar. Unfortunately, I didn't expect it to actually rename the main system user folder (just the shortcut in the Finder sidebar). Things started to stop working and stuff went missing almost immediately. Luckily, I found out how to reboot as some system user and mess around with some fancy command-line moves and the problem was resolved. But an ordinary user would never have known what to do and would have had to get some support.

This sort of thing shouldn't happen. If doing a normal action (such as renaming a folder and others listed in the article) is going to have such unexpected and severe results, then it needs to have some sort of warning or obvious way of communicating that these particular files/folders shouldn't be messed with. Especially on a Mac, where unlike Windows, most programs can even be moved about with no big issues. The system shouldn't fall apart because someone didn't realise that some particular folder is special.

Thanks to all for the tip on moving the MSUserData folder to ~/Library/Preferences I HATE that folder being in my Documents folder. Moving it did the trick. Thanks!

The king of stupid apps, imho, is Quicken, which still stores personal data files (named QuickenData by default) in the *application* folder, where it is oh so easy for the uninitiated to toss out their data along with the program when upgrading the software.

I know a guy who zoned out and trashed his Applications folder while cleaning up some disorganized directories. Guy had been using Apple computers since before the Mac, but I guess he just hadn't had his coffee that day...

First of all, sorry about the previous post. It was an old entry in my 1Password (annoyed look)

Second, I hope that most people who read this blog already know enough not to be told "don't move obviously useful files to the trash".

Last, come on! How can a person who actually uses the product be so dense as to delete a folder called "insert-product-name User Data"? ANd do we really need to Remind such people Not to do these things? Would it help? (chuckling)

A friend called me when he couldn't get an application to install because the disk image couldn't find an application to open itself. Turns out his kids had trashed his 'Utilities' folder, including the Installer util. If you're gonna let your kids use your computer, give them their own accounts and turn off admin access!

There's a better solution... Don't use entourage - I had so many problems in the years I used that - and so few (touch wood,) since I switched to using 'mail'!

Also remember how this applies to Mac apps like iDVD, i recently renamed some external drives, primary and backup. Then later on realized that My iDVD Projects lost link to all associated project files. Fortunately it asks you where they are and after some clicking around, you can recover. This also affects remote users configured for a default login to networked drives. Copying these files from one drive to another, would get error messages until the mappings were resolved. So kudos to apple for the checksums, but a little tedious.

I had a user do this to me. She told me, "My emails are gone". I couldn't figure it out - I had just updated her system, had been very careful to move everything over properly. I found that the "MS User Data" folder was in her trash, so I moved it back (thinking nothing of it). A little while later, she complained again. Her emails were missing again! At that point I asked if she had deleted her "Microsoft User Data" folder - she had. When I asked why, she didn't know. She just deleted it because "she didn't think it was necessary". Sigh. (Technically it is really MS's fault for putting the folder there, as it doesn't belong in that directory).
