My computer won't let me name any files! I can name folders, but only once when I create it. If I try to rename a file it will say "If you change file name extension, the file may become unusable." I have some Japanese songs I want to change into English and some Word Documents. By the way, I have a WindowsXP 2003.

Good catch by . The warning you saw appears because Windows uses the text after the last dot in a filename to decide how to open the file. Hiding extensions makes it easy to accidentally change that part, which is why Explorer warns you the file may become unusable. That is exactly why saw the message.

Simple, practical rules to avoid trouble: rename only the characters before the final dot and leave the extension alone (for example keep .mp3 or .doc). Make extensions visible so you can see what you are changing. If an extension was changed by mistake, adding the correct extension back will usually restore the file; if it still will not open, use Open With to pick the correct program and set it as the default. Always keep a backup before altering extensions.

Notes specific to your files: for music, consider editing ID3 tags (title/artist) rather than renaming files — most players display tag data and that keeps folders tidy. For Word documents, renaming does not change the document itself; to change file format use Word's Save As. Avoid illegal filename characters when renaming: \ / : * ? " < > | and avoid reserved names like CON, PRN, AUX, NUL, COM1, LPT1.

If renaming fails for other reasons, common culprits are the file being open or locked by a program, a read-only attribute, restrictive NTFS permissions, or read-only media (CD). Quick checks: close programs, copy the file to the desktop and try renaming, clear Read-only in Properties, or sign in as an administrator to adjust permissions. The suggestion from solves most cases, which explains why was able to rename files immediately.

Hello, have you got the option show filename extension selected?

have a look under tools > folder options >view (tab) and select the 'Hide file extension for know files'.

I suspect that when you enter the new filename it you don't include the extension, probably .mp3.

Has this helped?
