FAQ: Do GRID paths have a limit on the number of characters allowed on Windows platforms?

Question

Do GRID paths have a limit on the number of characters allowed on Windows platforms?

Answer

Yes, there is a limit on the number of characters allowed for a GRID path on Windows platforms.

GRID paths longer than 120 characters (including the name of a GRID) return an error message when a value attribute table (VAT) of a GRID is edited.

For example, when trying to add a new field to a GRID that has a path longer than 120 characters, the following error message is returned:

“Failed to add the field to the table/feature class”.

Likewise, deleting an existing field from a GRID that has a path longer than 120 characters returns the following error message:

“Failed to delete selected field”.

It is important to note this even in a geoprocessing environment if editing is being done on GRID tables (VAT).

Refer to the article in Related Information for information about path names' limits on GRIDs in UNIX environments.
