+# Sync Ignoring Large Files
+
+Initially, the plugin does not ignore large files.
+
+From the new version in May 2022, it can ignore all files with some sizes. But we need some rules to make the function compatible with existing conditions.
+
+1. If users are using E2E password mode, then the file sizes are compared on the **encrypted sizes**, rather than the original unencripted file sizes. The reasons are: the encrypted ones are in transferations, and the encrypted sizes can be computed from unencrypted sizes but not the reverse.
+
+2. Assuming the file A, is already synced between local device and remote service before.
+
+   - If the local size and remote size are both below the threshold, then the file can be synced normally.
+   - If the local size and remote size are both above the threshold, then the file will be ignored normally.
+   - If the local size is below the threshold, and the remote size is above the threshold, then the plugin **rejects** the sync, and throws the error to the user.
+   - If the local size is above the threshold, and the remote size is below the threshold, then the plugin **rejects** the sync, and throws the error to the user.
+   - When it somes to deletions, the same rules apply.
+
+   The main point is that, if the file sizes "cross the line", the plugin does not introduce any further trouble and just reject to work for this file.
