| => Open the new directory in Windows Explorer |
| is it a file? |
| => Open Windows Explorer and select the new file. |

| => Create a directory with the name of the SFX and extract into it |
| => Open the new created directory in Windows Explorer |
| |
| Semantic archive comment |
| ------------------------ |
| |
| The extractor looks into the file comment to determinate the behavior |
| while unzipping. YOU can influence the behavior when creating your |
| ZIP files. |
| |
| Following switches are possible: |
| |
| C_ASFX_CB_OVR = 'AutoSFX Conflict Behavior: Overwrite all'; |
| C_ASFX_CB_NEW = 'AutoSFX Conflict Behavior: Overwrite older'; |
| C_ASFX_CB_ASK = 'AutoSFX Conflict Behavior: Ask'; |
| C_ASFX_CB_AVO = 'AutoSFX Conflict Behavior: Avoid'; |
| |
| C_ASFX_CP_BEF = 'AutoSFX Comment Presentation: Before extracting'; |
| C_ASFX_CP_AFT = 'AutoSFX Comment Presentation: After extracting'; |
| C_ASFX_CP_NON = 'AutoSFX Comment Presentation: None'; |
| |
| C_ASFX_FC_THS = 'AutoSFX Extraction Target: Extract here'; |
| C_ASFX_FC_DSK = 'AutoSFX Extraction Target: Extract to Desktop'; |
| C_ASFX_FC_ASK = 'AutoSFX Extraction Target: Choose directory'; |
| |
| Special AutoRun.inf |
| ------------------- |
| |
| [AutoSFX] |
| Operation=open ; Part of ShellExecute. Usually 'open' or 'runass' (e.g. for admin privilegies) |
| FileName=AutoRun.exe ; The filename to be executed |
| Parameters= ; Optional parameters |
| Directory= ; Optional Working directory |
| ShowCmd= ; (See MSDN Reference) Usually WS_NORMAL or WS_HIDE |
| OpenUnzippedContent=true ; After we have opened the application, should we still show the extracted data in Windows Explorer? (Default behavior if not AutoRun is set) |
