It seems there is one file in each of my projects that gets corrupt and won't allow me to open Explorer. Even when I ignore the error message and try to delete the file, it says it is in use, even though it isn't in the time line.
My work around is to delete it via "Add new files" in Elements, it somehow allows me to it through there.
could you tell us about the name and location of the file. There are a number of temp files created while theporject is being edited and if some of these files may be being used by the organizer (in case you are using version 4 or 7). A possibel solution could be to close PRE. Check from task manager that the process has stopped and then delete these files.
