Dear developers, it is possible that some of the problems are due to the limitations of the file system for the length of the file names - 255 characters max. Version 107 has files with a greater length of 256 characters! For example:
C:\Program Files (x86)\1C Game Studios\IL-2 Sturmovik Battle of Stalingrad\updates\16-01-28\patches\16-01-28_data_graphics_LANDSCAPE_Stalin_w_ROADS_Binary_highways_VB.bin.3990B418F73AFADEA103C9F2ADBC5FB0.68630040.7E625A206FB4D3530FFD55DFFCB50B38.66039840.patch
