A large number of image files will be saved locally in the test of image collection demo. After a long time, there will be dozens of GB of data, occupying a large amount of disk space. Using Windows' right click delete is incredibly time-consuming, taking more than 10 hours. Try shift+del and it's still slow. Also tried the computer butler file shredding function, is also slow. There was no choice but to find another way.
Use the Windows command line tool (DOS instruction) to process.
1. Run the del command to delete files
Del Deletes only files in folders, but does not delete folders.
del /f/s/q dirname Copy the code
Add the parameter del
/P prompt confirmation before deleting each file. /F Forcibly deletes read-only files. /S Deletes the specified file from all subdirectories. /Q Quiet mode. The deletion of a global wildcard does not require confirmation. /A Select the file to delete based on the properties. Property Description r Read-only A archive S system H Hidden - The prefix indicates "notCopy the code
2. Run the rmdir command to delete the folder
The rmdir file is deleted together with the file.
rmdir /s/q dirname Copy the code
Attach the rmdir parameter
/s Deletes all subdirectories and files under the directories. /q is the confirmation that No longer asks for Yes or No action when deleting a directory.Copy the code
Del + RMdir is used together as an example
del /f/s/q dirname rmdir /s/q dirname Copy the code
The results of
It's much faster than Windows right click delete or Shift + del.
Use win10 built-in Powershell terminal, use rm instructions, surprisingly fast, absolutely!
rm -r * Copy the code
