To prevent damage to important system files and important data files prevent overwriting files that have only been read but not written to in a long time.
This way you can use an external disk or a disk on key, and be sure that that older stuff is write protected from viruses ruining your data. You can still get "infected" but your old data will be preserved.-- pashute, Jan 11 2022 1. You could use a proper operating system not some mickey-mouse jobby. I'm sure [8th] could of filled us in on this.
2. What happens if you actively want to edit an old data file? for example, I have a spreadsheet <yay! Spreadsheets!> which I add another column to every 5 or 10 years.
3. But I also have another spreadsheet <wow!> I made an hour and a half ago which I want preserved untouched forever. So age is not the only determinant.
4. So there should be some kind of permissions system, perhaps a dialogue box that pops up:
------------------------------ Are you sure you want to overwrite this file which is *23 years 11 months 23 days 9 hours 35 minutes and 16 seconds* old? [Yes] [no] ------------------------------
Which introduces our old friend User Error.-- pocmloc, Jan 11 2022 Of course you should be able to manually edit the file, but not without some intervention of yours.-- pashute, Jan 11 2022 Of course you should be able to manually edit the file, but not without some intervention of yours.-- pashute, Jan 11 2022 For instances of data duplication, as an example.-- RayfordSteele, Jan 11 2022 For instances of data duplication, as an example.-- RayfordSteele, Jan 11 2022 I can't see the use meself. System files should be protected by default naturally, while any files software creates should be cordoned off, like James Corden at a pie eating contest.-- 4and20, Jan 11 2022 random, halfbakery
