Ok, after playing around, I found out that it goes by Date Modified, and I'm 100% sure of that, because I've renamed files to change the Date Modified, and it shows up where it should in relation to the others.
Now my question is: Is there any other way aside from renaming them all again (there's at least 1300 pictures, and probably around 130ish people. If it boils down to it, I can just do the following:
1) Move all photos from SD card, to my PC.
2) Open up Photoshop's Browser (I think it's Elements Browser, but it's the picture browser)
3) Find each file (most are grouped together already, but some are spread out between others. Wouldn't be THAT hard to temporarily move those files that are scattered, and re-name them seperately, at a different time) but find each file "group", and do batch renames on each set, manually.
Is there any easier way than this? And before you ask, here's some answers
1) No, there is absolutely no way to organize them by name, date, size, or anything like that. It HAS to be Date Modified.
2) No, I'm not willing to buy a program, or download a free one from a weird site (but trusted sites like cnet and such are perfectly fine).
3) No, I don't want to try another app or browser like Astro (I think that's what I've been seeing everywhere). Reason being, I love how I can open this folder and scroll through my pictures, click on one and enlarge it, share it, etc.; all from right there. The photos themselves are of the same nature (I'm a photographer, and this series is of human art, so knowing where one set is out of thousand, isn't important.
4) Yes, I'm very picky and have bad O.C.D., so I won't sleep until I get these pictures in order.
Sorry for the long post, but this is bugging me bad. I haven't had any problems with my Droid's functionality until now. If someone can give me an easy fix to this problem, I'll stay on these boards and share my infinite wisdom with everyone (not trying to sound like the king of Android phones, but my main job is programming so I've been around PC's all of my life, and I've done other things such as modding the old X-Box classics, putting custom firmware on "unhackable" PSP's, rooted the Droid I have now probably 10 times, and so much more. So I do know a little.)
Terribly sorry for the long message, Here is the short version
1) Date Modified seems to be only method of sorting to keep in order when transfered from PC to Droid.
2) Need better method than renaming 1000+ files to modify the "date modified" (even with Batch rename, it would still take too long)
3) If someone can help me, I'll share every milligram of knowledge I have about Droids hardware/software (I need a new forums anyway!)
Thank you for any help. I will keep you posted on any changes. Like I said, I won't stop until I have figured this out to perfection.
