help on script

Hi,

I have the following script that I got help from the EEs a few months ago. It has been working well until this month.

We receive many files monthly in TXT, CSV, XSL and XLSX. I use Powershell to combine them.

It is giving me an error  "excel cannot complete this task with available resources" on the last step. It does not show the error unless I open the final combined file.

It is difficult for me to provide the files because I do not think it is files related. Here are the steps I have done:

There are over 800 files in the folder. I located the file that was stopped and removed. The error stopped on another file. When I removed other files and kept the "supposed error files", the code went well. There is no pattern.
