Organise files on your hard disk

Keeping your files organised is very important... but hard. Some people argue that in our age of desktop search we don't need to worry about folder structures. I disagree.

Many times, when I ask people for a copy of a file, they cannot find it. They realise that they aren't organised. They swear that they will go through and organise their files asap. Of course, when I ask them for another file a few months later, they cannot find it. Keeping you files organised is hard.

So, here is my guide to file organisation.

Keep your desktop clean

The desktop should only contain a few shortcuts to often used programs and the recycled bin. No files should be permanently stored on your desktop. None. Think of the desktop as your workspace. You cannot work efficiently if it is cluttered. As your workspace, the desktop should temporarily house files that you are currently working on. When you are done with the files, they should be archived - moved off the desktop to another folder for permanent storage.

To My Documents or not to My Documents, that is the question
Some people do not like the My Documents folder, usually located here: C:\Documents and settings\YourUsername\My Documents\
There are a few problems with the default path. The spaces in the pathname can be problematic for scripts. It is a silly design choice by Microsoft. If you are going to use the default path, put double quotation marks around the pathname to ensure that your scripts will work. Another problem with the default My Documents location is that (by definition) it is a well known storage area and is often targeted by malicious programs, such as viruses and trojans.

You may change the location of the My Documents folder by right-clicking on it, selecting Properties, and changing the Target Folder Location. My advice is to create a folder called Docs (C:\docs\), and to use this as your My Documents folder.

One Folder to Rule them All
Placing all important documents and files in one folder:
1. makes backing up files easy - just sync one folder and you're done
2. makes files easy to find
3. makes archiving easy

I name my top level folder according to the year, eg., 2006, 2007 etc. All documents to do with work go into this folder (not audio or video files). My 2007 folder currently contains the subfolders DMDX, ERC, Experiment, Greece Trip, MMM, NCN, PDF library, Praat scripts, Reading group, Thesis, UWS Ethics. Of course, your subfolders will differ depending on your purpose. Every day before I go home, I sync the 2007 folder on my laptop with the 2007 folder on my USB flash drive. When I get home, I sync the 2007 folder on my USB flash drive with the 2007 folder on my home PC.

A Year folder allows you to archive files that are no longer being used - for e.g., when 2008 begins, create a new, empty 2008 folder and start organising yourself again. From this point on, sync the 2008 folder every day. There will be some files from 2007 that you will need to keep working on, such as thesis.doc. Simply, use file versioning and create a new file (e.g. thesis02.doc) in your new 2008\Thesis\ folder. Leave your 2007 files where they are.

Using a Year folder has the added bonus of archiving your important documents in an intuitive, chronological order. This folder structure allows you to see which experiments were conducted, pdf files read, documents written, MMMs given, presentations prepared, ethics amendments approved, and so on, during which year.

Backup your files in five places

Picture this: you are in the fourth year of your PhD. You have written six chapters of your thesis. You have finished your statistical analysis. You are putting the finishing touches on your Interspeech conference presentation. You are drafting the final chapters of your thesis. The finish line is in sight. A virus reformats your computer. Or a power surge kills your laptop. Or your hard drive dies. Or...

File versioning
Backing up is very, very, very important. But you have to be smart. When you are working on an important document, such as a thesis, you will inevitably make numerous revisions. Do not save over your original file. Why? Imagine that you are working on thesis.doc, and as you are saving the document Word crashes and the file is corrupted. If you sync your files between devices, this corrupted file will overwrite your older, non-corrupted file because it was edited last and is therefore newer or more up-to-date. Bad news: you no longer have a working version of your thesis. Don't reach for a gun; instead save incremental versions (use Save As, not Save). For example, thesis01.doc, thesis02.doc, thesis03.doc, and so on. If thesis03.doc becomes corrupted, at least you will have a working version of thesis02.doc to fall back on, and will only lose some (not all) of your work.

Backing up
Make backing up easy for yourself. Keep all of your important files in one folder. I have a folder called 2007, with all my 2007 work. Every day before I go home, I sync the 2007 folder on my laptop with the 2007 folder on my USB flash drive. When I get home, I sync 2007 folder on my USB flash drive with my home PC. This means that every day my files are saved to three places. Of course this is not enough. Every week I save my work using other storage devices.

Here are seven backup options that I came up with. Choose five of them, and you'll be safe:

0. Your original files are on your hard drive (this doesn't count).

1. USB flash drive (also called USB key, pen drive, thumb drive, whatever) - Buy a good USB flash drive. Use it every day.

2. Communal external hard disk - Each postgraduate student room has an external hard disk. Use it.

3. Drive U: - You have 2GB of storage space. Keep an updated copy of your important documents there (not your sound or video files).

4. Home PC - Not everyone owns a home computer. Those who do should use it as a backup device.

5. Recordable media (CD or DVD) - MARCS laptops come with Nero. Burn a copy of your important files to CD or DVD. If you use a re-writable disk, you can use the same disk over and over again.

6. Online storage - There are many sites that allow you to store your files online. My favourite is Box.net because it's fast, but there are heaps of them. Find one that you like and use it.

7. Email attachments - Chances are that you email documents to your supervisor fairly regularly. Different versions of your files are probably sitting (as attachments) in your Sent Mail. This isn't really backing up, but it can save you in an emergency.

IZArc: Open any archive format

Archive files are basically containers of a number of other files, which make transportation and/or storage easier. They may also be compressed, meaning that they take up less room.

You are probably familiar with .zip files. This is the most popular archive format. Winzip is a popular program, which can create and unpack .zip files. However, Winzip cannot open many of the other archive formats. The same can be said for Winrar and .rar files, or Winace and .ace files, and so on. What's more, these are all commercial programs that cost money.

There is good news: IZArc is an excellent, free
archive utility, supporting nearly 60 archive formats, such as: 7-ZIP, A, ACE, ARC, ARJ, B64, BH, BIN, BZ2, BZA, C2D, CAB, CDI, CPIO, DEB, ENC, GCA, GZ, GZA, HA, IMG, ISO, JAR, LHA, LIB, LZH, MDF, MBF, MIM, NRG, PAK, PDI, PK3, RAR, RPM, TAR, TAZ, TBZ, TGZ, TZ, UUE, WAR, XXE, YZ1, Z, ZIP, ZOO.

Why would anyone buy Winzip, Winrar, Winace etc.? I don't know. You can replace all of these programs with IZArc. Do it now.
