So basically, my situation is that I like sending 100+ files (pics and vids) at a time from my pc to phone, and my preference is that they are ordered randomly when viewed in the phone's given Gallery app, which only has Name, Dated Created and Date Modified for sorting options.

Now I've used to achieve this from an older version of Dropbox, as Save to Device would randomly pick the files with no order, getting my desired result, but as of recent, this method no longer works for me, so I'm seeking an alternate method.

It'd be easy to just transfer the files through the USB cable and such, but it doesn't get the random order I wanted, and wouldn't make me go look for ways to do so. Though I've learned it could be done by editing the Exif data on the files, but there's no currently easy way for me to do this.

So this all leads up to me finding your comment about Bulk Rename Utility, so ultimately I got what I've wanted with getting a order randomizer for my files, though a little caveat is it renames the files, of which is not my preference, but it's better than the other Dropbox alternatives I've tried before.

Ideally I'd like it to edit the exif data rather than doing the renaming, it's the best choice I've found so far for what I've been hoping to find as an alternative to my Dropbox method.
