C-language implementation for modifying file suffixes

in the actual software development project, you may encounter the need to modify the suffix of the file ( For example, to modify the Doc format to docx format ) . This article provides a C Language implementation that modifies the file suffix and demonstrates the process of modifying the file suffix.

1. C Program Implementation

2. procedure for modifying suffixes

Step 1 :

in the local D disk, there is a call " Test " folder, under which there is a folder named " 123.doc " file, as shown in:

        Create a new two folder under either folder, named old2new " ( ) and " ( Indicates that the new suffix is modified to the old suffix and c " changesuffix.exe " Copy to two folders.

Step 2 :

under these two folders, create a new file named " Config.ini " configuration file with each configuration entry in the file as follows:

[General]

; Converts the old suffix to a new suffix, or converts the new suffix to the old suffix, 1--old, new, 2--new

Old2newornew2old =

; Old file suffix (support configuration multiple, middle has; separate)

Oldsuffix = Doc;xls;ppt

; New file suffix (support configuration multiple, middle has; separate)

Newsuffix = Docx;xlsx;pptx

" old2new " old2newornew2old " set to 1 , " new2old " in the folder " old2newornew2old " set to 2

Step 3 :

in the " old2new " folder under new name " Update.bat " batch file with the contents of the file:

changesuffix "d:\\test" 0

among them, " d:\\test " is the path to the file where the suffix is to be modified.

in the " New2old " folder under new name " Update_restore.bat " batch file with the contents of the file:

Changesuffix "d:\\test" 1

among them, " d:\\test " is the path to the file where the suffix is to be modified.

" old2new " and the " New2old " the following files are stored under two folders:

Step 4 :

individually double-click " Update.bat " and the " Update_restore.bat " , the conversion function of old new and old suffix can be realized.
