Search Manager Update

✨ New Feature: Extended Result File Support

• When the 4GB file size limit of FAT32 is reached during a search, an additional result file is now automatically created.
• The new file will have _ext appended to the original filename.

Example:

If the original result file is results.dat, the extended file will be named results_ext.dat.

This ensures full search results are preserved on FAT32-formatted storage devices.
