Seek a file management software, which can label files and facilitate search and classification when viewing.

I recommend a software for you, which is a free office platform. It should meet your needs.

General functions are:

1. file management: you can set the file title name at will; You can randomly classify or set multiple labels (separated by English commas); The software can be described in detail as required; You can save any file as an attachment (because there is a file title, you don't have to care about its original file name); It is worth mentioning that it also has two indexing methods: list and search, and the operation of search function is very simple.

2. Customer information and address book function: the address book can be imported from the mobile phone; Support multiple phone and email fields; Can be grouped or viewed; When viewing the list, hovering the mouse can display the mobile phone and mail, which greatly facilitates the viewing operation; E-mail can be sent in groups; You can send text messages in groups; This provides the greatest convenience for maintaining customers.

3. Email sending: You can view or send emails without logging in to the mailbox, and you can also receive emails from multiple mailboxes.

4. There is a short message function: computer short messages have many advantages over mobile phone short messages, such as fast input and copying.

5. It has the function of document circulation: it can be said to be the simplest way of document circulation, and it also conforms to the conventional process.

6. It has the function of schedule management: it has the function of perpetual calendar, can arrange schedules or notes at any time in the future, and has various reminder functions (list reminder, voice reminder and SMS reminder).

7. It has the function of summarization and abstraction, and it can also have the company's product catalogue and product introduction.

8. Have the map function: especially the satellite map function, which can be viewed in full screen and accurate to a building, providing strong support for people familiar with new cities or salesmen to plan and use.

9. There are many other tools. Go and see for yourself.

Finally, I would like to mention that it is very convenient and simple to find the input content, just search directly.
