Processing coverages or grids returns the following error message:
"Fatal Error: (INFDEF) directory full"
The two most common situations in which ArcInfo Workstation, GRID or INFO commands generate this error are:
- The command outputs a new grid, coverages or INFO file.
- An ArcInfo Workstation or GRID command modifies an existing coverage feature, grid's structure or INFO file. In this situation, the software usually creates a copy of the input coverage, grid or INFO file. It modifies the copy. Then it deletes the original and renames the copy to replace the original. The INFO file limit may be exceeded when both the original and the copy exist.
The INFDEF fatal error occurs when the software exceeds the allowed number of files in a single INFO directory. This limit includes INFO programs, reports, and special forms. It also includes the multiple INFO files associated with each coverage and grid stored in the ArcInfo workspace containing the INFO directory.
A version 7 INFO directory (created using ArcInfo Workstation version 7.0 or later) can hold up to 10,000 INFO files. This limitation is due to the INFO internal file naming convention. In a version 7 workspace, the numbers used to name internal INFO files range from 0000 to 9999. So, there can be at most 10,000 INFO files in a single INFO directory. This limits the total number of coverage and grids that can be stored in a single version 7 ArcInfo workspace.
A pre-7 version workspace allows only 3 digits to be included in the INFO internal file names. This limits the number of INFO files in a pre-7 version INFO directory to 1,000.
When you don't know if the ArcInfo workspace is a pre-7 or a 7 version workspace, use the TABLES or the INFO DIRECTORY command to see the internal INFO file names in the current workspace. Both commands lists the internal INFO file names. A pre-7 version workspace will have only 3 digits included in the file names listed in the INTERNAL NAME column. A version 7 workspace will have 4 digits in the file names listed in the INTERNAL NAME column.
