Hello all,
almost a year later I want to recommend a tool that might help.
http://www.handyfiletool.com/index.html
Handy File Tool (HFT) by Heatsoft Corp. is six years old, freeware and mainly a search tool.
Concerning this discussion, you can look for a filesize option like "larger than A and smaller than B".
I don't know, whether this helps, but the BIG advantage is the "basket". You can look for files all over your HDD space and collect the result in a basket.
Now you can do copying, deleting, renaming the results from the basket, thus changing all files in their original location.
If this works together with the search options you may have a ... well, a handy file tool at your hand.

Hello all,
I contributed a short impression about Dashlane in the following thread under General Discussion:

Won't repeat it here, but be aware, that it is NOT answering specific questions. But if works with Android quite well - as far as I put it to use.
