DONE: Are any of the files missing???

(1/5) > >>

nkormanik:

Perhaps not a request for a coding snack, but possibly.

There are existing programs which probably suffice.

But I'd like advice on which you would use, given the following circumstance:

Given:

--- One complete set of 'dummy' files, held within subdirectories of a primary folder:

c:\dummy set of images\subset 1\...
c:\dummy set of images\subset 2\...
c:\dummy set of images\subset 3\...
c:\dummy set of images\subset 4\...
etc.

--- One set of actual files, but not complete..., certain ones are missing:

c:\real set of images\subset 1\... (various ones missing)
c:\real set of images\subset 2\... (various ones missing)
c:\real set of images\subset 3\... (various ones missing)
c:\real set of images\subset 4\... (various ones missing)
etc.


--- All files in "Group Dummy" have unique file names.
--- "Group Real" file names correspond to Group Dummy names.
--- If all is perfect, there should be TWO of each file in the combined lot.
--- If a file is missing (from "Group Real"), there will only be ONE of that file in the combined lot.


Task:  Find out which files are missing in "Group Real."


Thanks.

rjbull:
er, can't you just DIR /B in dummy and real folders, and compare them with a diff program?

Carol Haynes:
How about Beyond Compare - shows you not only files in one folder and not the other but also files that have contents that don't match. See: http://www.scootersoftware.com/

I haven't tried it but this page may be worth a look too: http://www.techsupportalert.com/best-free-file-comparison-utility.htm

nkormanik:

rjbull, DIR /B /S is good.  That can get us a list of files of both folders.  Then strip away path.  Once the two lists are in hand, what diff program would you use?

Carol, remember the files are buried within subdirectories.  Most such programs as you mention want all files to be one level deep, no further.

Carol Haynes:
Beyond Compare works its way through trees (and even inside archives) very well. Ok it isn't free but it is very good - and you can use it from Explorer with a right click.
