文件备份器(Final).rar (117.32 KiB, Downloads: 328)
set /p source= Please enter the path of the file to be backed up:
:: Here, you can prompt to directly drag the backup target into the running window to obtain the source path
for /f "delims=:\" %%i in ("%source%") do set subarea1=%%i
:: It seems to be to obtain the drive letter of the source. Why not use set subarea1=%source:~0,1%
if not "%source%"=="" set source=%source%
:: The meaning of this sentence is unclear, please enlighten me
:: If you want to format the path, you need to use for %%p in ("%source%") do set source=%%~fp
if "%source%"=="" goto input_source
:: It is suggested to assign the selection of directly pressing Enter (that is, %source% is empty) to the operation with high frequency
if "%source%"=="0" exit
if "%source%"=="1" goto backup_task
echo "%source%"|find "%subarea1%:\" > nul
if "%ERRORLEVEL%"=="1" goto input_source
:: Judge whether there is a drive letter in the path? Can it be done with if "%source:~1,2%"==":\"
if "%source%"=="%subarea1%:\" goto forbid
:: Judge whether the path is the root path? When source is C:\\ or C:\., it will not work
if not exist "%source%" goto source_noexist
goto input_object
:: The meaning of object is object, which is ambiguous with the backup target. It is better to change it to target or destination

I respect your patience, but if you're only writing this batch script for file backup, it's actually simpler to use some third-party tools. For example: SecondCopy, or the synchronization software CmdSync, etc. Of course, personal environments are different, so methods vary. Mine is just a suggestion.
set _src=
for %%p in ("%source%") do if exist %%p set _src=%%~fp
if "%_src%"=="" for %%p in (%source%) do if exist %%p set _src=%%~fp
if "%_src:~1,2%"==":\" goto forbid
set source=%_src%

Re namejm:
Finally, I don't know what environment you use to write code? But from the fact that the width of the comment reaches 114, it seems that you may be using a wide-screen monitor, so there is no need to worry about the line break browsing problem of the comment. However, according to the code posted in the forum and my system environment (17"+XP+EditPlus2), whether the automatic line break function is enabled or not, the excessive width of the comment affects the readability of the code.

Re namejm:
The following statements can remove possible quotation marks in the path, convert the relative path to the absolute path, convert the non-standard path to the standard path (C:\\-->C:\), and judge whether the path effectively exists and whether it is the root path.
