I use WinMerge 2.8.6 to compare file with steps:
1. Click first file that will compare. (ex. C:\Branch\Test.txt)
2. Right click and choose "Compare To"
3. Click a folder (ex. C:\Trunk)
4. Right click and choose "Compare"
With this steps, WinMerge 2.8.6 can compare file automatically C:\Branch\Test.txt with C:\Trunk\Test.txt but WinMerge 2.10.0 can't do it. Why?
