HTC Incredible :: Disappearing Moved Photos IMAG.jpg From Phone Storage To SD Card?

I recently changed the storage location on my Incredible's camera from Phone Storage to Storage Card (i.e., my SD card). Yesterday I decided to move the previsouly taken photos "IMAG*.jpg" from the phone storage to the SD card and used the Astro app to perform this move. I made the mistake of using "move" rather than "copy-paste". Something went wrong and somehow none of the "imag*.jpg" that were previously on my phone's internal storage are neither there nor on the SD card.

Where could these files have disappeared to? Is there a "Trash" folder in Android like in Windows where these jpg files could be still hidden? Anyway to recover them? Using the search feature on Astro didn't reveal any of the newly disappeared jpg files.

Here's what I did using the Astro app:
step 1: navigated to /emmc/DCIM/100MEDIA
step 2: clicked on multi and selected all the jpg files there (about 15 or so), i.e., all file names turned orange.
step 3: clicked on Edit, selected Move.
step 4: navigated to /sdcard/DCIM/100MEDIA which already had a few images that I had taken since changing the default storage location in my camera.
step 5: clicked on EDIT, selected Paste.
That's when I got a message saying "unable to move" or some such error - I don't recall the exact words and I had to click ok only for the same error to appear again some 15 more times. I guess it appeared once per image.

I went back to /emmc/DCIM/100MEDIA (the phone storage location) and to /sdcard/DCIM/100MEDIA (SD card location) but the files aren't there in either location. Please note that I'm a noob to Android having only used Windows Mobile OS phones in the past. I appreciate any help and insight in this matter so that I don't loose files more important than some randomly taken pics.
