The VB 6.0 exe (24 kb) is a lot smaller than the Delphi exe (169 kb).
However, the VB distribution package is much bigger -
1.46 Mb vs 169 kb.
When used via Windows Explorer, both programs are fairly quick.
Warning: Both programs have been tested under MS Windows 95 only.
These programs were designed to let the user create a new directory using Windows Explorer. Using View / Options... / File Types, edit Folder and add a Create Directory menu selection. The command line should be C:\Utils\CreateDir.exe "%1" (as appropriate). Notice that Delphi requires the double quotes around the %1; for VB, the double quotes are optional.
To use this, in Windows Explorer, right click on any directory and select Create Directory. A dialog box displays the selected directory and allows you to enter the name of a new sub-directory. Various validity checks prevent the user from entering bad characters.
This procedure is more intuitive than having to open a directory, right click in the empty space, select New / Folder, and then having to re-name it.
