How to convert file name with path to short file name (DOS style) in Adobe AIR?

For example convert next path

"C:\Program Files\Common Files\Adobe AIR\Versions\1.0\Resources\Adobe AIR Updater.exe"

to

"C:\PROGRA~1\COMMON~1\ADOBEA~1\VERSIONS\1.0\RESOUR~1\ADOBEA~1.EXE"

Is there any algorithm?

Solution

  • Assuming your text portion is a string variable, you can split it by using "\" as delimiter. Then, you will have an array which you can use to check if each block is longer than 8 characters. While looping the array you can chop the last characters of each long block and put ~1. Since you're in the loop, you can progressively add to a temporary variable all these changes which will give you the final edited result at the end.

    The only part that's a bit tricky is to pay attention to .exe part at the end.

    So, if I were you, I'd start reading on String.split(), String.substring(), for loop, arrays
