The GROMA program uses different types of data files for work. Some of them are stored in the internal program format, while some have a universal format also used by other programs.
Table 38.1. File extensions used in the GROMA system
File extension | File content | Format |
---|---|---|
.crd | Coordinate file | Binary |
.crx | Index file of a coordinate file | Binary |
.mes | Measured data list | Binary |
.mex | Index file of a measured data list | Binary |
.prj | Project | Text |
.pic | Drawing prescription of a coordinate file | Binary |
.bmp | Bitmap for digitalization | Binary |
.rnf | Information for bitmap (transformation key, etc.) | Binary |
.cod | Code table | Text |
.txt | Text file | Text |
.par | Area size | Text |
.dst | Check distance file | Text |
.key | Transformation key | Text |
.pol | Transit traverse | Text |
In some situations, GROMA automatically creates backup copies of the files (e.g. before compression, etc.) Because you usually work with more files of the same name but a different extension, the backup files can't be named with the extension .bak. For this reason, the backup file name is created by keeping the original name, but using the character"~", as the first character of the extension and the other characters of the extension are moved by one position to the right (the last character of the extension ceases).
