+
+Automation scripts for Melissa's patient export workflow.
+
+## Rename and Move PT STMT.bat
+
+Scans a root folder for patient export directories, renames `export.txt` with today's date, and moves it along with all `.tif` files into a new dated subfolder.
+
+### What It Does
+
+For every folder found under the root that contains an `export.txt`:
+
+1. Renames `export.txt` → `PT STMT_YYYYMMDD.txt`
+2. Creates a new subfolder named `PT STMT_YYYYMMDD`
+3. Moves the renamed `.txt` file into that subfolder
+4. Moves all `.tif` files in the same folder into that subfolder
+
+### Expected Folder Structure
+
+```
+ROOT\
+  <patient_id>\
+    Patient\
+      Export\
+        export.txt       ← renamed and moved
+        1000001.tif      ← moved
+        1000002.tif      ← moved
+```
+
+After running:
+
+```
+ROOT\
+  <patient_id>\
+    Patient\
+      Export\
+        PT STMT_20260423\
+          PT STMT_20260423.txt
+          1000001.tif
+          1000002.tif
+```
+
+### Setup
+
+1. Open `Rename and Move PT STMT.bat` in Notepad
+2. Set the `ROOT` variable to your actual folder path:
+   ```bat
+   set "ROOT=C:\Users\Melissa\Documents\Patients"
+   ```
+3. Save and double-click to run
+
+### Notes
+
+- Uses `pushd`/`popd` to work around Windows' 260-character path length limit
+- Safe to re-run — `mkdir` for the dated folder will silently skip if it already exists
+- Date format is `YYYYMMDD` (e.g. `20260423`)
