Inno Setup如何在卸载过程中不删除特殊文件夹

Question

I'am wondering is it possible to keep my "special" folder on the partition after I uninstall my app? I need to keep some files for possibly next installation and it will be very usefull for me this time. Maybe is there any way to set exact location to uninstall or something like this?

Any ideas?

Answer 1

In order to avoid deletion of installed files/folders during the uninstall process you should use uninsneveruninstall flag described in [Files] section .

uninsneveruninstall

 Never remove the file. This flag can be useful when installing very common shared files that shouldn't be deleted under any circumstances, such as MFC DLLs. Note that if this flag is combined with the sharedfile flag, the file will never be deleted at uninstall time but the reference count will still be properly decremented.
