>>I am using ADIR to get a specific number of files from a directory based on a criteria. So, ADIR(laFile,gcFat+'thread\*.*') will create an array and I can now use ALEN(laFile,1) to get the file count. However, on big directory this is causing a big array to be created just to get the number of files. How can I optimize that?

Yes, based on that code, it could be optimized this way. However, the problem is with the creation of the array. I'll try Larry's suggestion.
