How to ignore SVN folders in WinMerge?

Uncomment some lines in builtin filefilter

WinMerge (Version 2.12.4) already includes a filter but (at least in my installation) the filters for Subversion, Git and Bazaar were commented out.

Navigate here: Tools | Filters | Filefilters | Exclude Source Control (double click to edit)

Edit the lines to look like this:

d: \\.svn$ ## Subversion working copy
d: \\_svn$  ## Subversion working copy ASP.NET Hack
d: \\cvs$   ## CVS control directory
d: \\.git$ ## Git directory
d: \\.bzr$ ## Bazaar branch
d: \\.hg$ ## Mercurial repository

Try Builtin File Filter

WinMerge (Version 2.12.4) already includes a filter to exclude source control files and directories, and it's called Exclude Source Control.

It works for Subversion, CVS, Git, Bazaar and Mercurial, and it doesn't require you to create a filter, you just have to apply it during the comparison.

Try making a Filefilter

WinMerge handles this just fine. You want to create and use a Filter. Under Tools | Filters... | Filefilters, create a new filter or modify an existing one.

It will look like this:

## Ignore Java class and jar files
f: \.class$
f: \.jar$

## Ignore subversion housekeeping directories
d: \\.svn$
d: \\._svn$

Save it, then when selecting items to merge, select the filter you defined from the Select Files or Folders dialog box. Bonus points: It will save this and use it as a default for future merges.
