VMware snapshots also use .ctk files. Like .log and .nvram files, .ctk files are small. Other less-frequently seen file types include the .vmem virtual machine paging file and the .vmtm configuration file for team data. Like VMSN files, VMEM files back up a virtual machine's memory. They exist when the VM is running or in the event of a VM crash.
Step 3. Add more vegetables to your diet. High vegetable sources of potassium include tomatoes, potatoes, squash, spinach, green leafy vegetables, brussels sprouts, and pumpkin. Try to have a vegetable with each meal and snack. Make a spinach, tomato and cheese omelet in the morning.
Potassium helps maintain normal blood pressure and also helps muscles, including the heart, to contract properly. Foods rich in potassium can lower the risk of heart disease, stroke, and high blood pressure. Talk to your doctor before making drastic changes to your diet, though. Here are foods that are especially high in potassium, listed from those with the highest amount to those that have less (but still high) amounts.
