The File | Save command writes information to disk using the current file name and type. You can also click the button on the quick access toolbar to save a file. If the file has not yet been saved, the Save As dialog is displayed so you can give the file a name and select the file type. If you would like to save an existing file to a new file name or change the file type, choose File | Save As instead of File | Save.
In the plot document, the Save command saves information in the Surfer .SRF file format that is not recognized by other applications. When you want to use Surfer information in other applications, you can use the File | Export command to create files in several useful formats.
Use Caution when Saving Excel Files!
A file can be saved in an Excel format from Surfer, but only one worksheet can be saved. Surfer does not allow for saving multiple worksheets in a single Excel document. If a multi-worksheet Excel document is opened and saved as an .XLS file from Surfer, be aware that only the single worksheet will be saved in the document. All the unused worksheets will be lost. In this case, a warning message is issued.
File Names, Formats, and File Extensions
When a worksheet file is saved, the file format can be specified by typing the appropriate extension on the file name. If the needed file is an ASCII DAT file, type a file name such as MYDATA.DAT. The .DAT extension tells the worksheet to save the file as an ASCII DAT file.
If the extension is not included in the file name the format is determined by the Save as type field. For example, if the name MYDATA is typed into the file name field and theSave as typefield is set toExcel Spreadsheet (*.XLS), the file is saved as
The file can be saved with any extension by enclosing the file name in double quotes. The file is saved with the name and extension typed in the file name box, but it is saved in the format specified in the Save as type field. For example, type the name (with quotes) "MYDATA.ABC in the file name box. If theSave as typefield is set toComma Separated Variables (*., the file is saved as
Surfer .SRF files preserve all the objects and object settings contained in a plot window. These files are called Surfer .SRF files throughout the documentation. Surfer can open .SRF files from previous versions as far back as Surfer 7. Surfer can save files to previous .SRF formats for sharing with other users. For example, the Surfer 15 Document .SRF file type can be opened in Surfer 15, but does not contain features that are in later Surfer versions. Beginning with version 16, the Surfer Plot (*.srf) file type is backwards compatible with all Surfer versions 16 and newer.
