Result
The received file information is stored in file_info variable by default. The variable represents an object with the following keys:
{
"last_write_time": "time of the last write",
"last_access_time": "time of the last access",
"creation_time": "file creation time",
"length": "file size in bytes",
"extension": "file extension",
"name": "file name with the extension"
}
Interaction with folders
This activity can interact not only with files, but also with folders. In order to specify the folder path, you need to copy it from the file explorer and paste it manually to the parameter “Path”. Keep in mind that the “Pick” button will not allow you to pick folders.
Usage Examples
This activity is useful when dealing with a huge number of files in a folder. Suppose we have a folder with files of different extensions and it is required to process files with the ".txt" extension. Then you may use this function to filter the needed files.
