I am looking for a free tool to make a snapshot of the filesystem structure (listing of files and directories, their size & timestamps) and can compare it 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?
OS can be Linux or Windows.
