I have a file folder that has files named with numbers such as 1.jpg. 2.gif 3.jpg 4.jpg

I need a method to get the greatest numbered file so I can continue adding additional files having the next number.

Is there any easy way to get the largest number file without having to loop through each file and check the names. Perhaps some way to sort by name and grab the greatest number and return that number?
 
You cant find the highest number in any kind of group if you dont look at all of the elements.
All sorting will eventually look at all of the elements.

But anyway, use the System.IO.Directory.GetFiles() to get all of the files (and no, GetFiles doesnt count as looking at each file.
You can put it in an array, then loop through the array, converting their filenames without extension into integers, and then sort the array. :)
 
how did you implement it?

thank you for the help and for the time
 
And why cant you do it yourself?
Sending answers via email defeats the purpose of a forum.

Put it into an array:
XYZ = System.Directory.GetFiles(...)
loop through the array, converting their filenames without extension into integers
For LV = 0 To XYZ.GetUpperBound
You need another array for an array of integers.
Sort the array:
Array.Sort(IntXYZ)
