each entry on the disk contains CRC of its data, we can compare CRC saved in meta && CRC of entry header && CRC of actual content

|
|
* Actor/Faction data
|
|
- GSON
|
|
- Filename : (refid) (with no extension)
|
|

|
|
|
* Prop data
|
|
- CSV

|
- Filename : (with no extension)
|
|
worldinfo2 -- tileprop
|
|
worldinfo3 -- itemprop
|
|
worldinfo4 -- materialprop
|
|
worldinfo5 -- modules loadorder
|
|
|
|
|
|
* Human-readable
|
|
- Tiles_list.txt -- list of tiles in csv
|
|
- Items_list.txt -- list of items in csv
|
|
- Materials_list.txt -- list of materials in csv
|
|
- load_order.txt -- module load order
|
|
|

## How it works ##
|
|
* If hash discrepancy has detected, (hash of csv in save dir != stored hash || hash of TEMD != stored hash), printout "Save file corrupted. Continue?" with prompt "Yes/No"

Alongside with save1.tevd (extension should not exist in real game), keep save1.backup.tevd as a last-working save. |
