Commented Issue: Copying .d64 error [7626]

I have two SD cards in my deluxe uiec/sd. When copying a file named something.d64 from one to the other, a space is added between the image name and the .d64. Renaming the file and getting rid of the space results in a working image but I thought I would let you know. The exact name of the file I was copying was "bails.d64" which turned into "bails .d64".

Which function did you use to copy that file?

There are two ways to do it between two sd2iec devices: file-to-file and "disk"-to-file (create image).
