I was comparing two asp.net site folders in WinMerge. The both were tied to source safe. The difference was showing .dll, .pdb and .scc files.
To exclude those files I created a new filter that has following entries:
f: \*.dll$ ## Filter for .dll
f: \.pdb$ ## Filter for .pdb
f: \.scc$ ## Filter for .scc
d: \\bin$ ## Filter for directory
I got the solution from here.
I could have updated the existing ASP.NET Development filter or the Sourcecode one but I just created new one.
Hope this helps…
