The number printed on the file tells us the number of granites there are per square centimeter. Therefore, if the number is lower it means that the grain is coarser and more aggressive for the nail. If the number is higher, the file will be finer and smoother.

• 80, 100 and 120: Used for acrylic or gel nails. Forget about using them with your natural nail if you don't want to damage it.

• 150: Medium grit. They are used to reduce the nail.

• 180: This is the most common grit, ideal for natural nails.

• 240: These files are used for final finishing and polishing natural nails.

• 400 and 1200: These are the finest grains that are usually used to give shine to the nail.

• Buffer: Use to give shine to nails. It also worked to polish acrylic.

Managing data or information within digital systems often hinges on a comprehensive understanding of file formats, sizes, and structures. Effective organization and retrieval necessitate familiarity with various content types, such as text, images, audio, and video, each requiring specific software for access and editing.

The term "grain" of files refers to the level of detail or granularity they possess. For example, a high-resolution image file has a finer grain than its low-resolution counterpart, as it contains more detailed information and, consequently, a larger file size. Similarly, a spreadsheet with intricate data entries is more granular than a summary report derived from that data.
