I have been using the Windows 7 system. Recently, when saving pictures online or saving files in Photoshop, it always appears "You do not have permission to modify files in this network location. Please contact the administrator to modify management permissions." After directly confirming the save, a 0 will appear. The text file comes out. But the second time, it shows that it already exists and whether to replace it.
Solution:
This problem occurs due to the NOD32 4.0 anti-virus software and file system real-time protection function installed in the system. Turning it off solves the problem. Enter NOD32 advanced settings, file system real-time protection, configuration, when creating files, remove √, as shown below:
Or go to the exclusion settings and exclude file extensions where "You do not have permission to modify files in this network location" appears.
