+## Unsave Posts After Downloading
+
+[This script](unsaveposts.py) takes a list of submission IDs from a file named `successfulids` created with the `extract_successful_ids.sh` script and unsaves them from your account. To make it work you will need to make a user script in your reddit profile like this:
+ - Fill in the username and password fields in the script. Make sure you keep the quotes around the fields.  
+ - Go to https://old.reddit.com/prefs/apps/
+ - Click on `Develop an app` at the bottom.
+ - Make sure you select a `script` not a `web app`.
+ - Name it `Unsave Posts`.
+ - Fill in the `Redirect URI` field with `127.0.0.0`.
+ - Save it.
+ - Fill in the `client_id` and `client_secret` fields on the script. The client ID is the 14 character string under the name you gave your script. .It'll look like a bunch of random characters like this: pspYLwDoci9z_A. The client secret is the longer string next to "secret". Again keep the quotes around the fields.
+
+Now the script is ready tu run. Just execute it like this:
+
+```bash
+python3.9 -m bdfr download DOWNLOAD_DIR --authenticate --user me --saved --log LOGFILE_LOCATION
+./extract_successful_ids.sh LOGFILE_LOCATION > successfulids
+./unsaveposts.py
+```
