Issue Details

When I specify a file path in some versions of LabVIEW, it seems that the data may not be transferred correctly if the path length and file name are too long or when the folder hierarchy is too deep. What is the maximum number of characters allowed in a LabVIEW path value? 

Solution

The following limitations apply to Windows 10 and Windows 11.

In LabVIEW 2025 Q1 and earlier, the maximum number of characters in a path value is 260.

In LabVIEW 2025 Q3 and later, the maximum number of characters in a path value is 32,767.

These limitations apply to file path controls, indicators, constants, and any value passed through a path wire.
