Every message you download into OE is stored in a special set of files in a single folder on your hard drive. Unfortunately, the space this e-mail takes up isn't automatically returned to its previously free state (where the hard drive space is available to Windows for storing data) once you delete the message. Instead, these files are altered in such a way that you can no longer see or get to that particular message from inside OE. So, THE MESSAGE IS STILL THERE!!! The only difference is that you can no longer see it in OE.
Before yah panic (as the realization hits you that all of those messages you THOUGHT you deleted will eventually fill up your hard drive). There is a simple way that you can permanently get rid of the garbage as well as clean these files of all this wasted space. It means getting yourself used to the habit of compressing each folder the moment you decide you've finished going through the messages they contain.
Here is what I mean:
Say you've been reading all of the jokes your friend Cindy likes to send to you every few days. If you followed the last two-part tip on creating folders and Message Rules, you're probably reading them from within a folder called Cindy (which is possibly a subfolder of one called Friends). Before you click on another folder (and leave the Cindy folder) to continue going through unread messages from your other friends, click to File/Folder and finally on Compact. You'll see a status bar window open up and hear some hard drive activity. What's actually happening is that OE is examining the special file that stores all of the messages that are in the Cindy folder and eliminating that wasted space mentioned earlier. When it's through (it could take some time depending on the number of messages stored in the folder), you will have compressed the special file and the wasted space will have been returned to Widows.
Yah have to get yourself into the habit of doing this for EVERY OE folder as soon as you're finished with it, you'll never have the problem of OE preventing you from having as much free hard drive space as possible.
For the first time trying this yah might want to:
Instead of choosing Compact, choose Compact All Folders in the directions above. This command will tell OE to go through ALL of those special files and get rid of ALL of the wasted space contained inside them. You SHOULD REALLY check your free hard drive space before and after running it:
Open up My Computer
Right click on your C:\ drive.
From the context menu that opens up click on Properties to see the info on your hard drive space.
