I do not get your question clearly but let me suggest you for closing, saving and rename files.
1. If you want to rename your Indsign file but cannot rename from the folder then do one thing open up your Indesign file and hit ctrl+shift+s (save as) and give your desire file name.
2. If your Indesign program cannot be close then open up "Windows Task Manager" (press ctrl+shift+esc) and under the "Processes" find and select "Indesign.exe" and click on "End Process". This will allows you to close your indesign program and do the same for acrobat (Acrobat.exe).
I have the same problem with InDesign 6.
Close tab = cannot rename folder (Folder1)
Close InDesign = rename folder as usual.
Tried to use Process Explorer, but to no success
Did you ever figure it out?
It's already been figured out. Close InDesign.
Yeah, great solution.
5 projects open, need to rename a folder - oh, you must close all your projects and close a program, before you can rename a folder!
Solution NOT accepted!
