How can I compare directory trees of huge size?
I am thinking a free tool to make a snapshot of the filesystem structure (listing of files and directories, their size & timestamps) would be ideal so I could compare the snapshot to another one made later.
Treecomp would be great for that but with a huge tree (I mean really huge!) it crashes because it tries to keep it in memory (4GB of memory are not enough)...
I worked around the problem by splitting the snapshots into pieces and compare these pieces. But that's tedious, and the problem can for sure be solved better.
Is there another free (best also open source) tool that I can try out? Or is there another way to do this that I am overlooking?
OS can be Linux or Windows.
Anyone have a good command line equivalent for linux? I've rolled my own with find and sha1sum, but I think this warrants a first class program. – Peter Lyons – 2010-09-10T15:28:32.820
What I've done in the past is produce a directory dump to file, and then compare the files with an ad-hoc program. – Daniel R Hicks – 2012-07-13T02:00:23.040
Beyond Compare 3? How many files and folders are we talking? How big of a drive is this? – Richie086 – 2012-07-12T23:29:07.600
