Solve the problem that WinXP can't access Win7 file

Windows XP system computers can't access Windows 7 shared folders. Some can see shared directories under Windows 7, but once they enter the directory, they will be prompted to have no access rights.
Workaround:
Go to the "Network and Sharing Center" setting to turn off the Windows firewall. Although there is an insecure risk to doing so, in order to achieve mutual access between different systems, it is only a last resort.
After closing the Windows Firewall, the next step is to go to the "Advanced Settings" on the left side of the firewall settings interface, and modify the "Inbound Rules" and "Outbound Rules". In both rules, find the <;File and Printer Sharing" option and set all of its options to “Allow all connection”.
After completing the above settings, you must go to the “User Account” and open the “Guest” account, and in the system service, open the corresponding sharing function. At this point, the sharing settings have been almost completed. Finally, set the corresponding shared folder. If you are familiar with the XP sharing settings, you can basically operate the following settings very conveniently. The concept of sharing Windows 7 settings is almost the same as XP. The difference is that the path is different.
The first step is to select the folder to be shared, right click and select “Attributes”, select ““Advanced Share” in the “Shared” tab, and will share this folder” The previous hook is hit, then click “Add”——“Advanced”——“Search Now” in “Permissions". Then select “Everyone” and <Guest” in the results of the search and confirm.
Through the above steps, you can basically solve the problem of 99% of shared folders that XP can't access. Of course, it is not ruled out that access exceptions still occur through the above methods. For this reason, it is recommended to temporarily disable the installation of additional anti-virus software or a third-party network firewall such as Skynet to prevent other network firewalls from obstructing access.
