What is the maximum recommended number of files per folder for best performance? RRS feed

  • Question

  • We have a manufacturing app that has put over 5000 files in one folder, and now it is very slow to open this folder and peruse it.

     I assume Explorer and other utilities have a practical maximum number of files to prevent disk/cache fetches. Anybody know this number?

  •  Hi David,

    Thank you for your question.

    In above suggestion, there is maximum number of file in a single folder, which is 4,294,967,295. But there is no maximum recommend number. As ZigZag said, it will depend on the hardware performance.

    If there are any questions regarding this issue, please be free to let me know.

    Best Regard,

    Jim

  • It could get better performance
    1) NOT to have contents indexed in addition to file properties, and
    2) NOT to create thumbnail files(Thumbs.db).

  • The "magic" number is dependent on the hardware you have.  If the hardware is a dual core it is different than if it is an i7.  Can we get more specific information regarding the setup?
