File Service

The File service offers limited access to the file system for operations such as copying or removing files.

Available Operations


File.copy(sourceFilePath: string, targetFilePath: string): boolean

Copies sourceFilePath to targetFilePath. Any directory components in targetFilePath that do not yet exist will be created. If sourceFilePath is a directory, a recursive copy will be made. If an error occurs, a JavaScript exception will be thrown.

Note: targetFilePath must be the counterpart of sourceFilePath at the new location, not the new parent directory. This allows the copy to have a different name and is true even if sourceFilePath is a directory.


File.exists(filePath: string): boolean

Returns true if and only if there is a file at filePath.


File.directoryEntries(path: string, filter: File.Filter): string[]

Returns a sorted list of the directory path's contents non-recursively, filtered by filter. The values of filter are equivalent to Qt's QDir::Filter.


File.lastModified(filePath: string): number

Returns the time of last modification for the file at filePath. The concrete semantics of the returned value are platform-specific. You should only rely on the property that a smaller value indicates an older timestamp.


File.makePath(path: string): boolean

Makes the directory at path, creating intermediate directories if necessary. Conceptually equivalent to mkdir -p


File.move(oldPath: string, newPath: string, overwrite: boolean = true): boolean

Renames the file oldPath to newPath. Returns true if successful; otherwise returns false. If a file with the name newPath already exists, and overwrite is false, move() returns false (that is, the file will not be overwritten).


File.remove(filePath: string): boolean

Removes the file at filePath. In case of a directory, it will be removed recursively.
