PDF files lose names and extensions when sent from Windows 10 to Android #277
Description
When transferring PDF files from a Windows 10 PC to an Android device via a "Chat Assistant" (File Transfer Assistant), the following issues occur on the mobile side:
1、Garbled Filenames: The filenames appear as unreadable characters (encoding issue).
2、Missing File Extensions: The .pdf suffix is stripped during transfer, making the file unrecognizable by the system and impossible to open directly.
3、Current Workaround: Users must manually locate the file in the file manager and append the .pdf extension to restore its functionality.
