In its simplest form, a search string consists of a sequence of text characters.
By enabling the Binary Data (Hex) option, the search string is treated as a sequence of hex bytes (eg, FF096C3A). Do not enter any spaces between the hex bytes.
You can also use specify hex characters within a text string by using the \x hex notation. For example, the above sequence of hex bytes can also be entered as:
If you use the \x notation, you will need to first enable "Allow hex characters in text search string" in the Search Options.
Case is not significant when entering hex data
When using \x notation, do not enable the Binary Data option
If \x notation is enabled and you actually want to search for "\x", you will need to enter "\\x"
