I am sure ... one time there will be coming the moment, when you need the value of an environment variable to create a proper folder path for your music files or to fill a tag-field with some specific external data. The current version of Mp3tag does not provide access to the system environment variables, so I have created a workaround to do so. There are two command line utility scripts in the attached zip file: - GetEnv.AppData.cmd - GetEnv.Temp.cmd Run these scripts from any folder. Each script will create two files in the folder "%APPDATA%\Mp3tag\data\actions" with the names: - GetEnv.AppData.mta, GetEnv.AppData.txt - GetEnv.Temp.mta, GetEnv.Temp.txt When running the "GetEnv.Temp.mta" action file from within Mp3tag against a selected music file, the action first reads the content of the data file "GetEnv.Temp.txt", then creates a new tag-field of name 'ENV\_TEMP', which holds the folder path string to the current user's TEMP folder. When running the "GetEnv.AppData.mta" action file from within Mp3tag against a selected music file, the action first reads the content of the data file "GetEnv.AppData.txt", then creates a new tag-field of name 'ENV\_APPDATA', which holds the folder path string to the current user's APPDATA folder. Hope it is useful, enjoy!
