Renaming File Extensions Uncovered
Every now and then you have one of those little problems, you are sure there must be a simple solution, yet for the life of you - you can’t find it.
Today I had the task of converting a few hundred supplied images into a useable format for web use. The supplied files were produced on a mac, and were free of defining extensions.
We Windows users do tend to find file extensions useful as do many online and offline applications.
Martin, our Senior Designer, who is recovering swiftly from allowing his 2 year old daughter to shave his head, managed to work out that the correct extension for these files would be a .tiff - (Tag Image File Format), having tried .eps , .bmp, .jpg and a few others.
I looked into the options available - those of you who have tried the Windows rename tool will understand that this was not the best way to proceed.
Initially I looked at Microsoft Picture Editor which, though not a great editor, has a very useful file renaming routine. The program, however, did not recognise the files I pointed it at as image files ( as they had no extensions ) - so refused to have anything to do with them. Next I researched several downloadable programs which promised to batch rename files, but had no real luck.
Ah, the joy of the Internet ( only last week I fixed my washing machine following advice on a forum), I found mention of a command line rename tool which I could use directly from Windows Vista. It recommended me to try opening up command line in the folder ( shift and right click ) I wished to edit :
ren *.* *.tiff
You can of course change the last bit to be anything.
As if by magic all files in the folder were immediately and swiftly renamed with the chosen extension.
Now that the files are viewable and editable Martin is batching them into .jpegs.
