if we have a lot of file names to add suffixes, it is too time-consuming to rename them one by one manually. I 'd like to share with you several ways to add suffixes in batches: HeSoft Doc Batch Tool Advanced Renamer, Online Tools, RenameFilesOnline, Windows Batch. These 5 methods are very simple. The following is a list of detailed operation procedures. As long as you follow the steps, novices can easily complete them!
Why add suffixes to file names in batches
1. Different versions of the same file need to be distinguished, and suffixes such as_v1 and_v2 should be uniformly added after the file name, which can not only quickly distinguish different modification stages of the file, avoid misuse of old files, but also avoid conflicts with the same name of the file.
2. For archived documents, year or month suffixes need to be added uniformly, such as_2025,_2025-12, etc. In this way, you can make a distinction with the following files, and you can also quickly locate the files by finding the time.
3. When the number of files in the computer is large, it is difficult for us to distinguish which files have been processed or reviewed and which files are being reviewed. Add_processed,_approved, and_completed tag suffixes to file names in batches, so you don't have to open the file repeatedly to confirm the status.
4. Many documents need to be made in multiple versions, such as the version viewed within the company, the version sent to customers, and the version released externally. Add a unified version suffix to the file name, such as_internal version,_external version,_desensitized version, etc., which is not easy to make mistakes when sending.
