Hi I have got several jpeg images on a cd , i am transfering them onto my pc and when i rename them it there is a text box that comes up saying that if i want to save it the file may become unusual, when i click save and go ahed with it, the name of the file changes to FILE
its one i have made myself, the files save as jpegs on the pc but when i try to rename it says that the extensions may become unusable, then when i click the file saves as one that my machine only recognises as file and does not allow me to open it.
It may be that when you are renaming the files you are forgetting to add the extension .jpg to the file name. There is a possibility your PC is set not to show file extensions thereby confusing the issue. Check in My Computer/Tools/Folder Options/View - Advanced Settings. There is an option there to "Hide extensions of known file type". If it's checked, uncheck it and you should see the file extensions of the files you are re-naming.
