<\/span>Can saving empty folders be possible?<\/div>
<\/p>\n

When a file named “$epskip$.$$$” is included in the archive, that file is always skipped during extraction.<\/p>\n

\u00a0In this way, saving empty folders can be simulated.<\/p>\n

<\/span>Can an \u201cinstaller with a digital signature\u201d be created with EXEpress 6?<\/div>
<\/p>\n

EXEpress 6 Pro comes with a function to create installers with digital signatures. See \u201cValidity check method for the self-extracting executable file\u201d in \u201cAdvanced Settings: Pre-startup processes.\u201d <\/a><\/p>\n

To actually add a digital signature requires using other software such as the Microsoft tools, so refer to the user manual for the software you are going to use.<\/p>\n

<\/span>Can an empty folder with no files be added to the archive file with EXEpress Compressor?<\/div>
<\/p>\n

CAB format specifications do not allow empty folders to be saved. <\/p>\n

A dummy file can be saved as a workaround if a folder that is not completely empty is allowable.<\/p>\n

<\/span>Can this be used to distribute applications created with VB6?<\/div>
<\/p>\n

EXEpress 6 does not support exclusive functions to install specific development environment runtime libraries in Windows system directories. However, the following methods can be used depending on the distribution format of the runtime library.<\/p>\n

    \n
  1. The EXEpress 6 standard file extraction feature can be used to install libraries that only need to have the necessary files copied.<\/li>\n
  2. When a separate install package (EXE file format or MSI file format) to install the library is provided, the install can be performed by starting the install package using the \u201cAutomatic Execute File after Extraction Function<\/a>\u201d in EXEpress 6.\u00a0<\/li>\n
  3. If the library is in ActiveX control or COM server format (OCX file or DLL file) and the files must be registered in the system after being copied, the registration to the system can be performed by using the \u201cActiveX control\/COM server registration function<\/a>\u201d included in EXEpress 6 Pro.<\/li>\n<\/ol>\n

    <\/span>What kind of expanded functionality is possible with the \u201cExtension module SDK?\u201d<\/div>
    <\/p>\n

    The following extended functionality is possible by the user developing suitable programs (DLL) by using the SDK (note that only a Japanese version is available).<\/p>\n
