The [_DROPPEDFILE](_DROPPEDFILE) function returns the list of items (files or folders) dropped in a program's window after [_ACCEPTFILEDROP](_ACCEPTFILEDROP) is enabled.
|
||
|
|
||
|
## Syntax
|
||
|
|
||
|
*Syntax 1*
|
||
|
|
||
|
> nextItem$ = [_DROPPEDFILE](_DROPPEDFILE)
|
||
|
|
||
|
*Syntax 2*
|
||
|
|
||
|
> nextItem$ = [_DROPPEDFILE](_DROPPEDFILE)(index&)
|
||
|
|
||
|
## Description
|
||
|
|
||
|
* After [_ACCEPTFILEDROP](_ACCEPTFILEDROP) is enabled, once [_TOTALDROPPEDFILES](_TOTALDROPPEDFILES) is greater than 0 the list of dropped items will be available for retrieval with [_DROPPEDFILE](_DROPPEDFILE)
|
||
|
* When using [_DROPPEDFILE](_DROPPEDFILE) to read the list sequentially (without specifying an *index&*), an empty string ("") indicates the list is over and then [_TOTALDROPPEDFILES](_TOTALDROPPEDFILES) gets reset to 0.
|
||
|
* When using [_DROPPEDFILE](_DROPPEDFILE) with an index (which goes from 1 to [_TOTALDROPPEDFILES](_TOTALDROPPEDFILES)), you must call [_FINISHDROP](_FINISHDROP) after you finish working with the list.
|
||
|
* Because it returns a string, [_DROPPEDFILE](_DROPPEDFILE) also accepts being followed by a string suffix ([_DROPPEDFILE](_DROPPEDFILE)**$**)
