Image Processor limited to 800 files at a time?

https://forums.adobe.com/people/Jarda+Bereza  wrote I guess... If you would have folder with 100 - 600 sub-folders inside your root folder... it could fail.

I think 100 folders and 600 sub-folders would contain tens of thousands of images.  The test I ran took sometime to start to run for as you point out the script  build a complete file list before it process the first image file.  The test I cancelled had 108 folders in the tree and 3,472 files.   I did cancel it after over 1200 files were process.  Remember the Script processes one image files at a time at any given moment it most likely only has two open documents the original source image and a copy an output file will be save from. If His machine stops after 800 files it means the file list was created and the script was able to process the first 800 files.  It is more likely that some source file  fail and cause the script termination.   If the Image process encounters a problem with a file it log that and  moves onto the next file. When files are processed the image processor generates a list of file that it had a problem with and notes that they were not processed.

I'm running the latest version of PS. I'll have to check when I get home about free RAM and scratch disk space.

Interesting. Good to know. I wonder what's going on with mine?
