🚀 Usage

./SCAS.ps1 [command] [options]

---

📋 Commands

🔹 Help

./SCAS.ps1 -h

---

🔹 Save Current Grid

./SCAS.ps1 -s <name>

Example:

./SCAS.ps1 -s clean_layout

---

🔹 List Profiles

List visible profiles:

./SCAS.ps1 -l

Include hidden profiles:

./SCAS.ps1 -l -a

---

🔹 Switch Profile

./SCAS.ps1 -c <name>

Example:

./SCAS.ps1 -c clean_layout

The current grid is first saved as backup_YYYYMMDD_HHMMSS, so unsaved artwork is never lost. Steam will automatically restart.

---

🔹 Delete

Backup & Delete Current Grid

./SCAS.ps1 -d

Creates automatic backup:

backup_YYYYMMDD_HHMMSS

Then clears current grid.

---

Delete Specific Profile

./SCAS.ps1 -d <name>

Works for both visible and hidden profiles.

---

🔹 Hide Profile

./SCAS.ps1 -hide <name>

---

🔹 Unhide Profile

./SCAS.ps1 -unhide <name>

---

🧪 Example Workflow

# Save default grid
./SCAS.ps1 -s default

# Customize Steam artwork manually

# Save new layout
./SCAS.ps1 -s anime_theme

# Switch between them
./SCAS.ps1 -c default
./SCAS.ps1 -c anime_theme

# Hide profile
./SCAS.ps1 -hide anime_theme

# Show all profiles
./SCAS.ps1 -l -a

📁 Example Folder Structure

Steam

    ├── 123456789
    │   └── config
    │       └── grid

⚠ Notes

• Steam will be stopped automatically when switching profiles.
• Library cache is cleared to force artwork refresh.
• Avoid running during downloads or updates.
• Profiles are stored inside your Steam directory.
• Profile names must be a plain folder name: ., .., .hidden and \ / : * ? " < > | are rejected.
• Old backup_* profiles are kept until you delete them with ./SCAS.ps1 -d <name>.

---

♻️ Restore / Uninstall

• To get artwork back, switch to one of the profiles or backups: ./SCAS.ps1 -l -a, then ./SCAS.ps1 -c <name>.
• To uninstall, delete SCAS.ps1 and, once you no longer need the saved profiles and backups, the Steam\userdata\SCAS_grid folder (./SCAS.ps1 -sl copies its path).
