Finder: How do I fix grayed-out files?

I put this together in Irfanview: First entry was using the file name after I dragged and dropped it. Hit enter, went to Finder, closed it, rebooted it and no change. (By the way, I've rebooted the computer twice since yesterday last post). So I noticed backslashes befor spaces in the file name that happens when I drag and drop the file in Terminal. So I tried just typing the file name exactly as it appears (see insert of a few of the grayed files). Still no results. Hit enter and repeated as above. So this is where I left it this morning. (I covered up the path up to the dollar sign.)

Oops, you're right:

-rwxrwxrwx@ 1 501 20 - 0 Jan 1 1980 /Volumes/SanDisk256/1-1-04 pics 005.jpg

No. Would it overwrite the original file? The file is still grayed. Yes I did a restart of Finder. I looked down the list and re-sorted by size.

I found one of those exec files (unix executable) at the bottom, also with zero bytes but with Modified date of January 1, 1980 at 12:00 am. It was created at 1:39 pm today and that's probably when I redid your suggestion and did the screen capture I posted. But the file name is truncated to 1-1-04 (no pics 005).

I'm sure this whole mess was created when I turned off the computer while all those files were being copied. Grayed out files are not that rare from what I've seen on the Web. Seems somebody would have written a small utility to deal with it. I've programmed in Qbasic only.

So 18,000+ pictures, showing zero bytes are not actually transferred? They're not salvageable? There's a lot of good files on that drive, but maybe there's room on a 1-terabyte Seagate drive to move them. It will just take a long time to do it (and this time only a few hundred at a time). But that's probably good advice. Thanks.

I'll have to find from where I moved them and see if I still have copies there. At least the file names are there. I'll be back, probably months later. Thanks for your help.
