I have used, with great success freeware called Cyflogic. Its from a company called CyFlo Ltd in Finland. I like features such as that you can open multiple windows and when clicking the file all the windows you have open or just some will open that particular file without having to close and reopen new windows each time. This way your gates are also maintained. Oh: and did I mention its FREE. The Software is pretty self explanatory but if you need some advice feel free to contact me. Cheers!
Ooops sorry Florian has already suggested it. The good thing about this tool is that it has a free license for non-commercial use (academic use) and the free version has all the features that are in the commercial one.
Does anyone can give me a link to download Flowing software? I've tried to download on the Flowing software's website but it didn't work as well in several websites... Thank you in advance!
