### 7.7.44 External Programs/Manage External Programs

The submenu External Programs allows you to edit the active layer or the active document outside of PhotoLine. Manage External Programs is a fast way to manage the list of available external programs (see chapter 7.10.1.43).

If you want to call an external program, you have three options:

- Edit Active Layer
The active layer will be saved in a temporary file, and this temporary file will be opened with the external program. If you save the file, PhotoLine will automatically replace the active layer with its content and will delete the temporary file afterwards.
- Edit Document
The whole document will be saved as a simple one-layer file. Aside from that, the behavior is the same as with Edit Active Layer.
- Edit Original File
Edit Original File is a bit different compared to the other options. The file will not be saved, instead the file, the current document is based on, will be transferred to the external program. Please note, that this file may have a different content than your document, if you already have edited your document.
