I have over 6000 image files linked to a spreadsheet by the file name. Unfortunately these file names have spaces in them (eg. 1 2345) and I want to remove the space between the 1 and the 2. I think I know how to do this in excel but wondered if there was a way to do the same on the actual image file names without going into each one individually and renaming them? The space is causing problems with uploads at the moment.
