Changing names of files etc.

If I have saved a file and try to give it a title, I get the message "If you change a filename extension the file may become unusable."This has only just started to happen for no apparent reason. If I say yes and change the file name I can still open the file, but the icon on the file changes to a "windows" icon

I think it means when you change the name of a file, it may come unusable only if you change the extension ie the exe, bmp, bat thingy at the end of the file name. For instance, if you change say, setup.exe to setup.cpy, you won't be able to run it. If you have a file called photo.bmp and you double click it, it will probably open in your paint or graphics program, PSP or paint or something - by changing the name to photo.*** it won't open automatically with that. I think the icons are associated with the extensions so that will change too. Hope this helps.

I have seen this message for the first time while changing a file name in Win XP. Even though you can't see the file extension. If you see the message again make sure that you only select the file name and not all of it which includes the extension. this is what I do now.

You can change the name but you cannot change the extension

I don't understand what you mean. It is perfectly possible to take a file called (for example) test.doc, and rename it to test.txt, test.bmp, test.xls, or just plain test (which is what I think rital90 is doing, i.e. forgetting to put the correct three letter extension after the '.').

The files were mainly photos, so I changed the caption to whoever or whatever the photo was of. When I changed the caption, I could still open the photo, but only by using the "open with" box EACH TIME, even though I ticked the "open with this every time" box. It is not really a problem, just a puzzle.
Thanks everyone for your help and advice. I am a beginner at this, but am learning all the time!!!

Start - My Computer - Tools - Folder Options - View - select 'Hide extensions for known file types'.

on the hand you could just type .jpg or .bmp or .tft (depending on file type) after each file name

rital90 - it is oh too easy when renaming files to miss off the extension (the 3 characters after the dot) - - - whatever you rename your files to, take care to remember what the extension is in case you over - type it.
