Although it sounds bizzare but thats true , i have 15000 images in one folder on the web . Thats how it is , i can't chnage the system now . But the FTP (i have only realized now) that shows only 1998 files only . so everytime some files are duplicated .
Now is there any solution to this . Does this is the problem with FTP client or i need to change some settings with the hosting provider. When i check from the website file manager it shows 15000 files.
