find files having same <property> as a file in filelist

[jimspoon]

I see that the following functions work:
sizefilelist1:
namefilelist1:
stemfilelist1:

These functions have names consisting of a file property name followed immediately by the name of a file list (e.g. filelist1:). They find files having the same property value (e.g. size, name, stem) as one of the files in the specified filelist. Just for example, I presently have 59 files/folders in filelist1:. "sizefilelist1:" finds 236 items, "namefilelist1:" finds 588 items, and "stemfilelist1:" finds 2178 items.

Just experimenting, I tried "extfilelist1:" but no items are found.

Are there any other "<property><filelist>" functions available besides sizefilelist:, namefilelist:, and stemfilelist: ?

Update: I just tried "parentfilelist1:" and 901 items were found. I suppose this would mean "children of the folders listed in filelist1:" Similarly "ancestorfilelist1:" returned 1436 items.

I can imagine something like "dmfilelist1:" to return items having the same "date modified" as an item in the specified filelist. I tried some variations of that like "datemodifiedfilelist1:" and "monthfilelist1:" but no items were found.

Thanks !! A specific use case - say I have files on a flash drive or memory card that I need to wipe and reuse, but first I want to make sure that I've copied the files on the flash card to some location on my hard drive. I can copy the names of all the files on the card to filelist1:, and then search "namefilelist1:" I bet there is also a way to find files on the memory card that have NOT been backed up to the hard drive, but since it's 2:21 AM here, right now my brain is not fit to figure that out.
