| 18 | Structure of a ViaThinkSoft AutoSFX Archive |
||
| 19 | ------------------------------------------- |
||
| 20 | |||
| 21 | 1. Extractor [UPX'ed] |
||
| 22 | includes DelZip190.dll (B4) as Resource |
||
| 23 | 2. ZIP (Offset adjusted) |
||
| 24 | File comment includes "ViaThinkSoft AutoSFX Archive" |
||
| 25 | 3. Optional: Authenticode Certificate |
||
| 26 | |||
| 27 | Process |
||
| 28 | ------- |
||
| 29 | |||
| 30 | 1. Extract DelZip DLL into TempDir |
||
| 31 | 2. Extract contents directly |
||
| 32 | 3. Open the extracted data and/or execute special AutoRun.inf (see below) |
||
| 33 | 4. Delete the DLL from TempDir |
||
| 34 | |||
| 35 | Behavior |
||
| 36 | -------- |
||
| 37 | |||
| 38 | ZIP has 1 file |
||
| 39 | => Extract in the same directory as the SFX |
||
| 40 | Is it a directory? |
||
| 41 | => Open the new directory in Windows Explorer |
||
| 42 | is it a file? |
||
| 43 | => Open Windows Explorer and select the new file. |
||
| 44 | ZIP has 2+ files |
||
| 45 | => Create a directory with the name of the SFX and extract into it |
||
| 46 | => Open the new created directory in Windows Explorer |
||
| 47 | |||
| 48 | Semantic archive comment |
||
| 49 | ------------------------ |
||
| 50 | |||
| 51 | The extractor looks into the file comment to determinate the behavior |
||
| 52 | while unzipping. YOU can influence the behavior when creating your |
||
| 53 | ZIP files. |
||
| 54 | |||
| 55 | Following switches are possible: |
||
| 56 | |||
| 57 | C_ASFX_CB_OVR = 'AutoSFX Conflict Behavior: Overwrite all'; |
||
| 58 | C_ASFX_CB_NEW = 'AutoSFX Conflict Behavior: Overwrite older'; |
||
| 59 | C_ASFX_CB_ASK = 'AutoSFX Conflict Behavior: Ask'; |
||
| 60 | C_ASFX_CB_AVO = 'AutoSFX Conflict Behavior: Avoid'; |
||
| 61 | |||
| 62 | C_ASFX_CP_BEF = 'AutoSFX Comment Presentation: Before extracting'; |
||
| 63 | C_ASFX_CP_AFT = 'AutoSFX Comment Presentation: After extracting'; |
||
| 64 | C_ASFX_CP_NON = 'AutoSFX Comment Presentation: None'; |
||
| 65 | |||
| 66 | C_ASFX_FC_THS = 'AutoSFX Extraction Target: Extract here'; |
||
| 67 | C_ASFX_FC_DSK = 'AutoSFX Extraction Target: Extract to Desktop'; |
||
| 68 | C_ASFX_FC_ASK = 'AutoSFX Extraction Target: Choose directory'; |
||
| 69 | |||
| 70 | Special AutoRun.inf |
||
| 71 | ------------------- |
||
| 72 | |||
| 73 | [AutoSFX] |
||
| 74 | Operation=open ; Part of ShellExecute. Usually 'open' or 'runass' (e.g. for admin privilegies) |
||
| 75 | FileName=AutoRun.exe ; The filename to be executed |
||
| 76 | Parameters= ; Optional parameters |
||
| 77 | Directory= ; Optional Working directory |
||
| 78 | ShowCmd= ; (See MSDN Reference) Usually WS_NORMAL or WS_HIDE |
||
| 79 | 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) |
