Description
The Folder command creates and returns a new object of the 4D.Folder type. The command accepts two syntaxes:
Folder ( path { ; pathType } { ; * } )
In the path parameter, pass a folder path string. You can use a custom string or a filesystem (e.g., "/DATA").
Only absolute pathnames are supported with the
Foldercommand.
By default, 4D expects a path expressed with the POSIX syntax. If you work with platform pathnames (Windows or macOS), you must declare it using the pathType parameter. The following constants are available:
| Constant | Value | Comment |
|---|---|---|
| fk platform path | 1 | Path expressed with a platform-specific syntax (mandatory in case of platform pathname) |
| fk posix path | 0 | Path expressed with POSIX syntax (default) |
Folder ( folderConstant { ; * } )
In the folderConstant parameter, pass a 4D built-in or system folder, using one of the following constants:
| Constant | Value | Comment |
|---|---|---|
| fk applications folder | 116 | |
| fk data folder | 9 | Associated filesystem: "/DATA" |
| fk database folder | 4 | Associated filesystem: "/PACKAGE" |
| fk desktop folder | 115 | |
| fk documents folder | 117 | Document folder of the user |
| fk home folder | 118 | Current home folder of the user (usually /Users/<username>/) |
| fk licenses folder | 1 | Folder containing the machine's 4D license files |
| fk logs folder | 7 | Associated filesystem: "/LOGS" |
| fk mobileApps folder | 10 | |
| fk remote database folder | 3 | 4D database folder created on each 4D remote machine |
| fk resources folder | 6 | Associated filesystem: "/RESOURCES" |
| fk system folder | 100 | |
| fk user preferences folder | 0 | 4D folder that stores user preference files within the user home folder |
| fk web root folder | 8 | Current Web root folder of the database: if within the package "/PACKAGE/path", otherwise full path |
If the command is called from a component, pass the optional * parameter to get the path of the host database. Otherwise, if you omit the * parameter, a null object is always returned.
On Windows, in merged clients, the location of built-in folders is modified if the
ShareLocalResourcesOnWindowsClientBuildApp key is used.
