**Describe the bug**
Drag & drop non-APK file;Push file to device
There is a bug in pushing files to the device
1. Unable to push compressed files such as *. zip, prompt:"adb: error: failed to copy 'D:\Documents\Downloads\ABC.zip' to '/storage/emulated/0/Download/.': remote couldn't create file: Is a directory"
2. After pushing a file with a long file name, the file name will be truncated, such as ABCDEFGHIJKLMNOPQ12345678.xlsx, which will be changed to ABCDEFGHIJKLMNO on the device

On errors, please provide the output of the console (and `adb logcat` if relevant).

```
Please paste terminal output in a code block.

Please do not post screenshots of your terminal, just post the content as text instead.

Reproduce the drag-and-drop push on Windows 11 with a .zip file and a long filename, recording the exact device-side results. Start by tracing the file-push path used for non-APK files; no source file or test is named in the report. Done means both files are pushed successfully with their intended names, and regression coverage verifies these cases.
