The editplus configuration modified in Windows 7 cannot be saved.

I believe that all users log on as new administrators rather than administrators. The software is installed under the system drive letter by default, for example, C: \. in Windows XP, this will not cause any problems, but in Windows 7, the problem will come out.
1. editplus. If you do not log on with the highest administrator privilege, the parameter for saving editplus will be restarted.ProgramIf it becomes invalid, You need to right-click the program file and select "Run as administrator" to save the set parameters.

2. tomcat. If you start Tomcat in the bin directory, you also need to "run as administrator". Another situation is, to manually change the properties and other configuration files of the project under the webapps directory, We can display the modified results without restarting tomcat, however, files under the Windows 7 drive letter cannot be changed (if you log on with the highest administrator permission, this will not happen). Then, you can simply move tomcat to D: \. The problem is solved.

The above programs are installed under the system drive letter. The default value is c: \. If it is a Windows 7 system, install the development tool below other drive letters as much as possible.
It is also not ruled out that there are special cases, which were found in the Oracle configuration file. I chose to install the configuration file tnsnames. ora on the F: \, net service in Oracle and cannot be modified. The operation is as follows:
In this way, you can change the files in the client_1 folder and subfolders, or set a single file.
