To increase the size of your swap file on Linux Mint, follow these steps:
### Look how much swap you currently have

```sh
free -h
```
### Turn off the current swap file
```bash
sudo swapoff /swapfile
```

### Resize the swap file
Replace `XG` with the desired new size (e.g., `4G` for 4 GB):
```bash
sudo fallocate -l XG /swapfile
```
If `fallocate` is not supported, use:
```bash
sudo dd if=/dev/zero of=/swapfile bs=1M count=4096
```
(for 4 GB, adjust `count` accordingly)

### Set the correct permissions
```bash
sudo chmod 600 /swapfile
```

### Format the swap file
```bash
sudo mkswap /swapfile
```

### Enable the new swap file
```bash
sudo swapon /swapfile
```

### Verify swap space
```bash
free -h
```

### Make it permanent
Ensure the swap file is reactivated on reboot by adding this line to `/etc/fstab`:
```bash
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
```

Your swap size is now increased.
