Thanks, I am aware of this as I will need to 'zero' the camera from time to time.
Also, you can rename files in the camera memory card using a connected computer in Windows Explorer or similar if you want to say, run on from a certain number.
Here is a useful one for people who like to 'get their hands wet' when working with computers.
It is easier to work within the file system using Windows Explorer but with a command line switch so that it opens to the root drives. You will, by this method see 2 panes on your screen, the left pane will have drives which can be expanded, the right will show the sub folders and files.
Create a shortcut on your desk top and paste the following command line into the dialog box.
"C:\Windows\Explorer.exe /n,/e, C:\"
Without the inverted commas
You can give any name to your shortcut, recommend "File Manager" to avoid confusion with Internet Explorer.
When you open it go to the "Tools" menu and select "Folder Options" Click the "View" tab and clear the check box that says "Hide File Extensions", you can also check the box "Show Hidden Files".
Using this you can easily copy files from say pen drives to HDD and so forth in an easy manner. Why Microsoft hide file extensions is beyond me, I suppose they cater for a reading age of 4 yrs and want people looking at pictures instead of reading English. File extensions tell you what type of file you are looking at, examples: jpg = image, doc = Word Document, xls = Excel spreadsheet etc
If using Vista you will have to go to Control Panel to find Folder Options
