Local History for Visual Studio automatically creates a history of your files every time they are saved. The history can be compared with the current version.
It's not obvious how to add a label. I want to right click for a context menu but nothing shows up. At least a text label could be added somewhere on the window. Use "L" to add a label.
Sometimes LocalHistory saves backup files with absolute path and not relative and with small letters.
These backup files is not visible in Local History window.
Normally backup files are stored like (for solution in d:/Projects/MySolution and MyProject): d:/Projects/MySolution/.localhistory/MyProject/SubDirectory/1448363004$MyFile.cs but sometimes it creates directories like: d:/Projects/MySolution/.localhistory/d/projects/mysolution/myproject/subdirectory/1448363004$myfile.cs`
It happens very random, sometimes many times a day, sometimes many days without problem...
