File.createTempFile naming problem

Question

Hello All,
I am using WIN XP .I am creating a temporary file with the following code
File temporaryDll = File.createTempFile("abcd", ".dll");In the temp directory , though I marked in code deleteOnExit to temporaryDll , it creates files with abcd1234.dll , abcd1235.dll n so on .
The temp directory gets filled up with these number of dlls with diff suffix. Is there any mechanism or any code snippet will I get , to make sure that only one dll will get created n deleted after JVM termination.How can I check in the code , file already exists or not , because at every time it create new filename?
I have tried by deleting all abcdxxxx.dll from temp dir , I ran the code but wondered after watching in temp dir , abcd1234.dll file created instead abcd.dll .
Looking forward for help.
thanks
Ani

That's because you original files all end with a "2" and not the 4-digit number you want. "Original file#" takes the number at the end of the original file.
For example:
IMG_1234    >> "1234"
IMG_1234-2 >> "2"
Why are your originals all end with a "2"? Probably because toy imported some duplicate files and lightroom added "-2" to their name to avoid a filename collision.
Check you folders for duplicates.
