What is the chronological order of these backups? Is 0 the most recent or the oldest? Are they created each time an edited program is saved? Thanks
User manual - UR10e e-Series - SW 5.13 - English international (en), page 282 says:
File Filter
You can specify the file types shown. After selecting Backup Files, this area displays the 10 most
recently saved program versions, where ’.old0’ is the newest and ’.old9’ is the oldest.
So each time you save a file:
’.old0’ is the newest backup file
’.old9’ is the oldest backup file
