Number tags

These tags generate numbers, letters, and counts that can be inserted into filenames.

`<Inc Nr:start:step>`	Inserts an increasing number. `start` can be any number and defaults to 1. The optional `step` controls the interval; `<Inc Nr:1:2>` produces 001, 003, 005, 007, and so on. Values are automatically padded based on the number of items. You can disable padding in the renaming settings, or force a length by writing `start` with leading zeroes, such as `001`.
`<Dec Nr:start:step>`	Works like `<Inc Nr>`, but inserts a decreasing number. `start` sets the first number and `step` sets the interval between files.
`<Inc NrDir:start:step>`	Works like `<Inc Nr>`, but counts separately for each folder. `start` defaults to 1, and `step` behaves as it does for `<Inc Nr>`.
`<Inc Alpha:start:step>`	Inserts increasing letters. `start` can be any letter and determines the letter case. Use more characters to set a minimum length, such as `<Inc Alpha:AAA>`. The optional `step` behaves as it does for `<Inc Nr>`.
`<Inc Hex:start:step>`	Inserts an increasing hexadecimal number. `start` must be a decimal number and defaults to 1. See `<Inc Nr>` for the behavior of the parameters.
`<Inc Roman:start:step>`	Inserts an increasing Roman numeral. `start` must be an integer and defaults to 1. See `<Inc Nr>` for the behavior of the parameters.
`<Rand:min:max>`	Inserts a random number. Use `min` and `max` to specify its range.
`<Rand Str:length>`	Inserts a random lowercase string using the letters a to z. Use `length` to set its length. To produce uppercase letters, use the `upper` tag modifier, for example `<Rand Str:8:upper>`.
`<Num Files:pad>`	Inserts the number of files in the file's directory, excluding subdirectories. The value is automatically zero-padded. Use `pad` to override the padding; for example, `xxx` pads to three digits.
`<Num Dirs:pad>`	When renaming a folder, inserts the number of its subdirectories. The value is automatically zero-padded. Use `pad` to override the padding; for example, `xxx` pads to three digits.
`<Num Items:pad>`	Inserts the total number of items in the list. The value is automatically zero-padded. Use `pad` to override the padding; for example, `xxx` pads to three digits.
