Here you can adjust, how PhotoLine handles saving.
If Create backup file when saving is activated, on saving a document the original file won‘t be overwritten. It will be renamed and on Windows "bak" will be appended to its filename extender. For example the original file "test.pld" will be renamed to "test.pldbak". On Mac OS a "~" will be appended to the filename, so "test.pld" will become "test~.pld". If there is already a backup file, this backup file will be deleted.
You can define, whether you will be warned, if the chosen file format can’t handle all information contained in a document. The warning lists up all features, that are lost on saving. But PhotoLine tries to save the document as correct as possible. Optically there is often no difference. But it can happen, that text layers are converted to image layers or the result is a single image layer.
Another option is, whether to work with the reduced data after saving. Without request the data stay the same.
Additionally you can define a color, that is used as replacement for transparency, if the given file format doesn’t support transparency.
Finally you can determine a file format as default file format used for saving. You can choose between PLD, TIFF, JPEG, GIF and PDF. Furthermore you can choose to always use the previously used file format.
But note, that only the PLD-format ensures, that a document is saved without loosing information. Only if you are saving a file as PLD, you can edit it the same way after loading like you did before saving.
