回复 1# 304802301
以下代码中变量 v 是自定义的固定减量，假设为 30GB 的字节值
仅当D盘剩余空间大于固定减量时才生成空字节文件...- @echo off &setlocal &set "v=32212254720" &md "d:\test" 2>nul
- for /f "tokens=2 delims= " %%a in ('wmic volume get Caption^,freespace^|find /i "D:\" ') do (
- for /f %%v in ('powershell "if(%%a -gt %v%){[Math]::Round(%%a-%v%)}else{0}" ') do if "%%v" neq "0" fsutil file createnew "d:\test\test.txt" %%v)
- pause&exit/b
