+# Export Sync Plans
+
+## What's this?
+
+Everytime the plugin starts a sync, it gathers all required information together, generates a "sync plan" of every operations to every files and folders, and assign the corresponding actual operations.
+
+Thus, if something goes wrong, we should check the sync plan firstly.
+
+## How To Export The Plans?
+
+Please read through the following instructions.
+
+### Disable Auto Sync Firstly
+
+You should disable auto sync to avoid any unexpected running.
+
+### Manual Sync If Not Yet
+
+You should at least sync once, so that at least one sync plan is generated and saved. If you have synced the vualt before, there should be some sync plans already saved.
+
+### Export To The File
+
+Go to the plugin settings, scroll down to the section "Debug" -> "export sync plans", and click the button "Export". \*\*It would generate a new folder `_debug_remotely_save/` in your vault, and generate a file `sync_plans_hist_exported_on_{a_timestamp},md.` inside that folder.
+
+## How To Read The Plans
+
+Open the genrated `sync_plans_hist_exported_on_{a_timestamp},md.`. You should see a json, or multiple jsons. Every json represents a sync plan.
+
+A sync plan looks like this:
+
+```json
+{
+  "ts": 1646960867560,
+  "remoteType": "onedrive",
+  "mixedStates": {
+    "abc.md": {
+      "key": "abc.md",
+      "existRemote": true,
+      "mtimeRemote": 1646566632000,
+      "sizeRemote": 56797,
+      "remoteEncryptedKey": "abc.md",
+      "changeMtimeUsingMapping": true,
+      "existLocal": true,
+      "mtimeLocal": 1646566632000,
+      "sizeLocal": 56797,
+      "decision": "skipUploading",
+      "decisionBranch": 1
+    },
+    "New folder/": {
+      "key": "New folder/",
+      "deltimeRemote": 1646925354372,
+      "existLocal": false,
+      "existRemote": false,
+      "decision": "keepRemoteDelHistFolder",
+      "decisionBranch": 9
+    }
+  }
+}
+```
+
+We usually care about the `mixedStates` property. As you may guess, every item in `mixedStates` represent a file or a folder.
+
+We should find out the file/folder we are interested in (or we believe something goes wrong), then checkout the following properties:
+
+```
+decision
+  What decision is made.
+
+decisionBranch
+  It's a mark of the actual logic in the sync code. Useful to debug.
+
+existRemote
+  Does the file/folder exist on the remote service?
+
+mtimeRemote
+  The "last modeified time" on the remote service.
+
+deltimeRemote
+  The "deletion time" on the remote record.
+
+existLocal
+  Does the file/folder exist locally?
+
+mtimeLocal
+  The max of "last modeified time" and "creation time" locally.
+
+deltimeLocal
+  The "deletion time" locally.
+```
+
+The `decision` SHOULD be determined by the modified times and deletion times, by the logic described in [the doc of sync alogorithm](../sync_algorithm_v2.md). In short, we collect four timestamps (`mtimeRemote`, `deltimeRemote`, `mtimeLocal`, `deltimeLocal`), and respect the max timestamp and its corresponding operation.
+
+## Common Issues
+
+Some users report that their "last modeified time"s or "creation time"s are not set correctly by the operating system. In this case, the plugin cannot do anything because it determines the sync plan by comparing the timestamps. It's suggested to check the settings of the operating system or check whether other programs are doing something to the files.

+The plugin works under the browser environment in Obsidian, so CORS is an issue. Obsidian starts to provide a rich API `requestUrl` for version >= 0.13.25 to bypass the CORS issue. But if the users are still using an older version of Obsidian, they need to configure CORS on server.
