To clear the Seafile cache on your computer, you can follow these steps: Open the Seafile client application on your computer. Click on the "Account" icon in the top-right corner of the application. Select "Settings" from the dropdown menu. In the "Settings" window, click on the "Advanced" tab. Under "Advanced Settings", click on the "Clear file sync cache" button. A confirmation message will appear asking if you want to clear the cache. Click "OK" to confirm. Wait for the cache to be cleared. This may take a few minutes depending on the size of your cache. Once the cache is cleared, you will be prompted to restart the Seafile client. Click "OK" to restart the client. After the Seafile client restarts, the cache will be completely cleared. *IMPORTANT NOTE*: Clearing the cache will remove all synced files from your computer. These files will be downloaded again when you sync with the server. Do login to the Web app to ensure all your files are up-to-date and make sure you have a reliable internet connection before clearing the cache.
