批處理ren重命名文件為何不按num順序排列做一個批處理，可以批量修改文件名，但修改后，文件名不規則。不按num順序排列。我的要求是修改后的文件名是按1 ，2，3，4，5，……排列。但實際修改后，有一段連續，有一段不連續。請達人指點一下。

echo off
set num=0
setlocal enabledelayedexpansion
for /r%%i in (*.flv) do (
set /a num+=1
rename %%i guanyia!num!%%~xi 2>nul)
endlocal
goto :eof
nclick="copycode($('code0'));">復制代碼

請版主幫我移一下位置了，發錯位置了，沒法刪了。謝謝版主。補充：未運行批處理前：C:documents and SettingsAdministrator桌面ie9.batbox300020C004DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C014DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C024DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C034DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C044DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C054DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C064DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C074DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C084DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C094DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C0A4DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox300020C0B4DDF8E7A617C052540FBD81C158C-6E89-3110-408C-A4E7EAD38CFB[1].flvC:documents and SettingsAdministrator桌面ie9.batbox3000214004DC8530D865A0296F3354ABD09D3-DD82-0E04-A4E6-16836ACCD111[1].flvC:documents and SettingsAdministrator桌面ie9.batbox-10-1014.56.flv運行批處理后：C:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓10.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓11.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓12.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓13.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓14.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓15.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓2.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓3.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓4.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓5.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓6.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓7.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓8.flvC:documents and SettingsAdministrator桌面新建文件夾 (3)了凡四訓9.flv改名后本應有1.flv，但是沒有。這還好一點多，后綴文件名改成其它的，多運行幾次，效果又是不一樣，中間有不連續的。感謝Hello123World 回答，你的1.jpg一直到20.jpg是連續的，但我的關鍵是改名后文件名有不連續的現象。
