I have someone asking me to a reg value that will change extension from lower case to upper case. So an example will be there are creating video that is an .mp4 and they want to make it an .MP4. First I did not think it would make a difference but I cannot find anything on the internet. Any ideas?


Thank you,

Windows will normally show filenames in lower case even if you create them in upper case. The actual case of the filename isn't changed, just how it is displayed (which can be confusing). To correct this I change this DontPrettyPath value to 1. If you actually want to rename many files, I recommend software like Ant Renamer or Rename Master. Scott.

So if I understand correctly it does not matter if the extension is upper or lower case because the system should read it either way.

That is correct. Windows NTFS preserves case, but is case-insensitive. For example Windows NTFS sees "filename.mp4" and "FileName.MP4" as the same file, while other OS might see them as different files. This can cause problems with links to files uploaded to web servers, since most Unix based file systems (and web servers) are case sensitive. Scott.

If you are having problems with uploads to websites, would you use the name changer software you suggested or is there another method that would be better? Thank you very much for your insite on this.

For web servers it is best to stick to all lower case as a convention. You can use a rename program to quickly and easily change lots of files to lower case before uploading. Scott.
