Both are file manager aplication for Nokia Symbian mobile phone especialy for S60 v3 family (OS 9.x). The main difference is… X-Plore is a pay application not free but Y-Browser is a freeware mobile phone application. If you only need the functions of file organization, choose Y-Browser will make you have saving a lot.
This mobile apps have developed by Lonely Chat Games (LCG). Some interesting features that I like… are have a shortcut to inbox when sending something through bluetooth so no need to exploring various folders to find it. Can make zip compress file directly so I can send file through email more faster.
In addition… with the X-Plore can create a shortcut to a folder, so that fast to access some folder.
This is a freeware file manager for Symbian mobile phone. Although a freeware… you cannot underestimate for it. I think this freeware powerfull enough.
You can set a command shortcut, so that just tap key pad to do something like copy, paste, or another. You can use a different orientation view direction with y-browser so have a landscape view. Which obviously you do not need the money to use this.
