When I use Google Docs, make some Docs give them a sequence and save them in Google Drive, it turns something like the following: 1. Some file name 10. 11. 12. 13. 14. 15. 16. 17. 18. Some file name 19. 2. 20. 3. 4 5. 6. 7. 8. 9. Some file name In above case 10 doesn’t follow 9, but it follows 1; like this, 20 doesn’t follow 19, it follows 2. So to avoid this problem I used different number system, and it ran in sequence without any problem. See below. 10] Some file name 11] 12] 13] 14] 15] 16] 17] 18] 19] 20] Some file name 21] 22] 23] 24] 25] 26] 27] 28] 29] Some file name (I think it should work well up to "99]".) This type of numbering helps me to see documents in exact sequence as I want, nothing is lost, no eyes trouble and no wastage of time. Please note that it is experimental, if there would be any changes I would update this post. Note: It has been edited 3 times.
