I can help you with your WinXP file extension problem.

First you need to tell XP to show you the file extensions for all files (it hides them by default).

From any explorer window:

  1. select Tools
  2. then Folder Options
  3. now choose the View tab
  4. now scroll down to "Hide extensions for know files"
  5. UN-check this box
  6. select Apply, then OK

Now back in any explorer window, your files will be listed with their extension, such as "file.txt".
You are able to rename this file to anything you want now, just add the ".txt" at the end & would won't get that message.

I hope that helps.

Go to control panel then go to folder option then click on view tab. On the list you'll find a option named "Hide extensions for known file type". Enable this option and click OK. Now you can rename your files easily.

Try to change the file name without changing the extension of the file name. Extension which is denoted by 3 letters followed by dot decide the type of the file.

This is a common issue.
Most people don't really know what a file extension is.
Every windows file has a three letter extension to let the OS know how to handle the file. Typically it looks something like this FILENAME.EXT where EXT is the extension.
To avoid this error message you have two options

One is to make sure when changing the file name you DO NOT highlight the extension
.
The other is to make sure you note the extension and include it after the new file name.

for example: a file called FILE001.ext MUST be renamed to NEWFILENAME.ext


Hope this helps

This happens when you are trying to rename a file and either don't add a file extension (such as .exe, .doc, .jpg, etc) or are changing the file type's extension from one to another.
The easiest way to avoid this is to only change the file name and not the extension, or turn off the option to view common file extensions.
Detailed instructions on how to disable the option to show all file extensions is listed below.

When i turn on my bluetooth this error msg appears " unable to perform bluetooth operation".


You will get this message when you try to send a system file. Rename first the file name,its extension and send it. After transferring it to the other phone, rename it back to the original file name and its extension.

Need a driver download


Here you go: http://dennisalbert0.tripod.com/Knopfler/robo351.ps
Download and save the file, then rename it to: robo351.exe, so the last letters (after the period) are "exe" instead of "ps".
Windows will ask you "If you change a file name extension, the file may become unusable. Are you sure you want to change it?", click Yes.
Then double click the file, and follow the instructions.
Regards,

Changing file names


Normally you will get a message to the effect of "if you change the file name it may effect other users who try to open this file" something like that. File extensions usually look like this C:documents/file.123/exe. etc.... As long as you're changing it normally and not in the extension manor (like the example), then you should be fine in changing the name. Try this; make a copy of the file, rename it, then see if it is still usable. If so, then you shouldn't have any problem renaming the others. Try this and let me know.

My foldders file extension got changed automatically


Can you still open it? Are you talking about a file extension, or a folder name? Folders themselves don't have extensions...

Maybe you should just make a copy of it, then try to rename the folder name/file extension to whatever it was before, then try to open it.
