SYMPTOMS

While working in Visual C++ on a project with source files in many directories, the performance of the IDE may appear to be slow or non-responsive.

CAUSE

This can happen if you have your source files spread across 63 or more directories on FAT or FAT32 partitions. The method that Visual C++ uses to get file change notifications scans source files in the 63rd and above directories every 5 seconds.

RESOLUTION

Some possible resolutions are:
  • If your operating system is Windows NT or Windows 2000, place all of your source files on an NTFS partition.NOTE: If the project is on an NTFS partition, Developer Studio scans a single file so the amount of activity should be significantly less.

  • Place your source files in less than 63 directories.
  • Reduce the number of source files in the 63rd and above directories.


STATUS

This behavior is by design.
