These options control the creation of backup files when you save a modified file to disk. You can control where backups are stored, how many old backups to keep and options for controlling the style of the backup file name.
"I have been using the CRiSP editor for about 3 years. It is by far one the best text editors I have ever used. It is very reliable, and I have yet to lose any data using it. It makes the editing and compiling process effortless, and it frees up more time for other tasks. The colorization, buffering, and column editing features are well worth the cost of this software."
