*The name of the functions written in italic may vary from phone to phone
*The larger is the space used at C, the longer will last the backup process.If your phone has a fast processor, use some file explorer and copy large files to the phone memory (C: drive) before trying backup trick, to have a free memory between 1,5 MB and 2MB.This will give you time enough to edit the files
*If the backup is completed when you're still editing a file that's in use, you won't be able to save your changes.Repeat the process, and try to be faster
*Depending on the phone model,some files like Cdbv3.dat can't be changed even with this trick
E:\Backup\
Then rename backup.arc to backupLatest.arc, Lastbackup.arc, or anything else that will help you to remember it's your current backup.When you need to restore the backup of phone memory from card, rename it back to backup.arc
