Technically, AC.09 within each category is reserved for the archive. The top 09 category is also for Archives. But I don’t think that archiving a whole ID or, God forbid, category, is a good idea because you will have gaps in your numbering. It’s OK to have gaps in the numbering but the gaps should be intentional. I need to know that if there is a gap, the number is available. If I archive the whole AC.ID and move it to AC.09, I get duplicate AC.ID codes which is suboptimal.
On the other hand, I do want to get old irrelevant stuff out of sight. So, I decided to avoid creating ID for temporary projects. This is where I put dad’s files:
- 21 People
- 21.12 Relatives
- Dad *(memorabilia - journals, letters, photos)*
- 31 Houses and Apartments
- 31.11 Repairs and Maintenance
- My House
- Archive
- YYYYMMDD some old project
- YYYYMMDD project 1
- YYYYMMDD project 2
- **Dad's apartment
- YYYYMMDD New locks
- YYYYMMDD Kitchen remodeling**
- 31.12 Ownership
- Archive
- My old house
- My House
- **Dad's apartment**
- 31.13 Sale
...
This way AC.IDs don’t become obsolete and remain active and relevant. Subdirectories may become obsolete. They don’t change the “address” (AC.ID) but may move to the attic (Archive subdirectory). If I sell dad’s apartment, the directory will nicely fit next to my old house in the Archive.
It’s a bit dispersed (files related to dad’s apartment are spread across different AC.ID) but well defined, easy to find, and nicely fits into the existing schema - if I move, I know exactly where to put files for the new home.
Same principle for other Project files - no AC.ID per project. Have AC.ID Projects or AC.ID Project Type and file projects in timestamped folders that can be archived after completion.
For cars, I have
- 32 Cars, Bikes, Scooters
- 32.11 Purchase
- 32.12 Repairs and Maintenance
- 32.13 Registration
- 32.14 Manuals and How-Tos
- 32.15 Sale/Disposal
No AC.ID per car because they will become obsolete someday.
Another principle - any subdirectory can have an Archive folder for irrelevant stuff (e.g. Timestamped submitted school essay drafts) with only the latest relevant versions remaining in the subdirectory.
