Concatenate String and Int to form file name prefix

Question

I am working with PowerShell to create a renaming script for a number of files in a directory.

Two questions here:

I have a string variable $strPrefix = "ACV-100-" and an integer counter $intInc = 000001 and I wish to increment the counter $intInc 1 -> 2 and then concatenate the two and store it in a variable $strCPrefix in the following format: ACV-100-000002.

I believe the $intInc will need to be cast in order to convert it once incrementing is complete but I am unsure how to do this.

Secondly, I have found that the script will display 000001 as 1, 000101 as 101 and so on... I need the full 6 digits to be displayed as this will form a file name. How do I keep or pad the numbers before I process the concatenation?

Answer 1

$intInc = 1

$strCprefix = $strprefix + "{0:000000}" -f $intInc # give ACV-100-000001

hope can help
