Filed upload Error

Hi, I have a problem about upload file to server in DS2022.  

Hear is the message : 

Unable to upload C:\\Users\\User\\Documents\\Discovery Studio\\Results\\Build3DDatabase_2022_07_05_135639_729\\Input\\all_2.sdf: Permission denied by Admin to upload file all_2
vcSoapUtils::InternalUploadViaCGI: Pipeline Pilot exception rethrown
FileData::Upload: Pipeline Pilot exception rethrown

I have two test files. 

The file size is about 200mb and 800 mb. 

After I set the maximum file size 100000000 (mb) in the Pipeline Pilot server homepage on the Administrator portal,

200mb test file runs well. 

But 800 mb test file failed. 

Is there other method to fix it ? 

Thanks in advance for your help.
