Deleted records may be recovered as long as the HEC-DSS file has not been squeezed. When a file is squeezed, all deleted records are physically removed.
You can undelete records in three ways: undelete all records in the file, select the records to undelete from a list, or undelete the records that you just deleted.
To undelete records from a HEC-DSS file:
1. From the Edit menu, point to Undelete.
2. To undelete all records click All. A dialog box will appear to confirm that you want to undelete all of the records in the file. Click OK. A confirmation message will appear that states the records have been undeleted.
3. To undelete the records that you have just deleted click Last Deleted. A dialog box will confirm that you want to undelete the records that you just deleted. Click OK. A confirmation message will appear that states the records have been undeleted.
4. If you click Select, a list of the previously deleted pathnames will open, as shown below:
5. Check the boxes next to the records that you want to undelete, or click Select All to undelete all records in the list. You can unselect the checked records by clicking Unselect All. Once you have made your selection, click OK to undelete those records and close the dialog. Alternatively, you can click Apply to undelete the records and leave the dialog box open. A confirmation message will appear stating that the records have been undeleted.
