automatically determine which files are already there versus which new ones should be copied without overwriting anything: something that Windows Explorer has never done very well without confusion and manual intervention/decisions by the user.
Thanks, Mike.
I just didn't point out the fact that Flashpipe will copy a folder full of files to second location and really checks them.
For example, let's say that you altered one letter or added a space in a sentence in a previous letter, and you saved it to be copied to your special documents folder later.
Later, you dump the folder with all these working copies to the Special Doc folder, and Flashpipe will detect that a change was made and copy that document to the destination. The rest it will "skip" because they are identical.
Windows copy and paste is going to ask you if you wish to overwrite ONE or ALL, and then proceeds to copy a few hundred files unnecessarily.
Let's put this in the context of images. Qimage Studio (and other apps) will keep track of, and save any changes you made you your Raw files by creating a sidecar file. I think PS calls it .xmp and Qimage Studio calls its file .qrs.
As you are perusing your images in a folder you might decide to touch up a few. A skinch lighter on this one, or a tighter crop on that one. All done! Now let's copy that folder to our backup location so all will match.
Flashpipe will see the altered xmp or qrs and copy only the ones you fooled with.
It is checking the innards of the file and not just a filename match.
