Once you have selected the highest value  which is  12  in my example  you can then declare it as integer and increment your value    FileList    1    2    11   foldername    int  FileList 2    1  foldername

You can specify the type of a variable before it to force its type  It s called  dynamic  casting  more information is here     string    1654   integer    int  string   string   1   Outputs 16541   integer   1   Outputs 1655     As an example  the following snippet adds  to each object in  fileList  an IntVal property with the integer value of the Name property  then sorts  fileList on this new property  the default is ascending   takes the last  highest IntVal  object s IntVal value  increments it and finally creates a folder named after it     For testing purposes   fileList      PSCustomObject    Name    11      PSCustomObject    Name    2      PSCustomObject    Name    1       OR   fileList   New-Object -TypeName System Collections ArrayList   fileList AddRange    PSCustomObject    Name    11      PSCustomObject    Name    2      PSCustomObject    Name    1        Out-Null   highest    fileList       Select-Object       n    IntVal   e      int     Name            Sort-Object IntVal       Select-Object -Last 1   newName    highest IntVal   1  New-Item  newName -ItemType Directory   Sort-Object IntVal is not needed so you can remove it if you prefer    int   MaxValue   2147483647 so you need to use the  long  type beyond this value   long   MaxValue   9223372036854775807
