I have migrated some projects from TFS to Visual Studio Team Services (formerly Visual Studio Online) following these steps. After that I realized that I have an extra partition (with the same size and free space as the Windows partition) with a lot of folders and files created during de migration. Most of folders and files are empty. Only some of them have source files (migrated files).
Folder name examples: i10_7, i10_null, i11_7, i11_null, i20_14, i20_null, i21_14, i21_null,... File name examples: 1457433532708.txt, 1457433533840.txt, 1457433534475.txt, 1457433534476.txt,...
So is it safe to delete the files? How can I remove this partition?
