If we have many files to add suffixes to uniformly, manually renaming them one by one is just too time-consuming. Here are several methods for batch adding suffixes: HeSoft Doc Batch Tool , Advanced Renamer, Online Tools, RenameFilesOnline, Windows batch processing. These five methods are all very simple, and detailed operation procedures are listed below. Just follow the steps, and even beginners can easily complete the task!
Why Batch Add Suffixes to File Names
1. When the same file needs to distinguish different versions, adding suffixes like _v1, _v2 uniformly to the end of the file name can quickly differentiate between modification stages, avoid using old files by mistake, and prevent filename conflicts.
2. For archived files, adding a year or month suffix uniformly, such as _2025 or _2025-12, helps distinguish them from subsequent files and allows quick file location by searching for the time.
3. With a large number of files on a computer, it becomes difficult to tell which files have been processed or reviewed, and which are still under review. Batch adding marker suffixes like _Processed, _Reviewed, _Completed to file names eliminates the need to repeatedly open files to check their status.
4. Many files require multiple versions, such as internal company viewing versions, versions sent to clients, and publicly released versions. Adding uniform version suffixes to file names, like _Internal, _External, _Sanitized, makes it less likely to make mistakes when sending.
