I apologize if this has been asked before, but I could not find the answer. I am running the latest build of ATI 10.0 Home. I configured a task to do a file (not image) backup. In the "Source Files Exclusion" dialog box, I added some directories such as: G:\Temporary Files (there are subfolders and files underneath this directory) E:\RECYCLER (to not backup my E: drive's recycle bin) G:\RECYCLER (to not backup my G: drive's recycle bin) I also added other folders to exclude using the format: Drive_name:\folder_name After running the task to do a full file backup, I see that these folders were still backed up. Why are they still being backed up? Next question: The "Source Files Exclusion" dialog box also has the option to "Exclude all system files and folders". Can you describe and give a sample list of Windows XP system files and folders that would be excluded if this is checked? I know in principle what system files and folders are, but want to know explicitly what exactly they are for Windows XP (they are not documented in the Acronis User Guide). Thanks.
