The extensions dialog box takes a long time to open

Last Published: April 25, 2020


Opening the extensions dialog box takes minutes.


The USEREXT directory contains a lot of data. When you open the extensions dialog box, ArcView checks this directory for extension files. If there is a lot of data in this directory, or sub-folders, it takes a long time for ArcView to look at all the files.

Solution or Workaround

Follow one of these solutions:

  • Change the variable setting for USEREXT.

    See the ArcView online help topic USEREXT for directions on how to set this variable.

  • Perform file maintenance on the current directory and remove any unnecessary files. The recommended maximum amount of data in this directory is 100MB.
