Saving really high resolution chart/graph images from excel is still a challenge. Especially, scientific journals have explicit requirements for the submission of figures: Most commonly they require high-resolution TIFF files.

MiniTool Partition Wizard aims to maximize disk performance. It helps create/resize/format partition flexibly, convert disk between MBR and GPT disks, convert partition between NTFS and FAT32, and convert dynamic disk to basic without data loss in a few clicks.

The big plus is its UI, that makes it easy to use all the disk manipulation tools without any prior knowledge about it.

A regular expression (shortened as regex) is a sequence of characters that specifies a search pattern in text. Typically it is used by string-searching algorithms for "find" or "find and replace" operations on strings, or for input validation. It is a technique developed in theoretical computer science and formal language theory. The four main tasks Regex performs are: to find text within a larger body of text; to validate that a string conforms to a desired format; to replace text (or insert text at matched positions); and to split strings.

Your search capability will go to another level if you know how to use Regex! Take a look at some of most commonly used regex and you will be amazed by the applications.
