I have a software package called Home Designer 2014, from Chief Architect, which uses *.plan files. If I open a *.plan file from a network location and try to save it I get an error message that the file is locked. Attempting to delete the file from File Explorer also runs into a lock error, with an explanation that the file is open in ESET Service. The same thing happens if I try to open/save the file from a mapped drive network location. If I open/save the file from a hard drive located on the computer protected by ESET there is no problem. Any ideas what's going on and how to fix it? I tried adding an exclusion for *.plan files, and one for *.plan files specifically on the mapped drive path, but that doesn't help.
