How to rename SharePoint list attachment file name or append the date/time to the file name

Hi,


I would like to create flow to rename the file name of the sharepoint list attachment. Please let me know if anyone has any idea on how to do it. I am new to MS-Flow. 

For e.g:

User uploads Lotus.jpg and I want to rename it as June-19-5:00PM-Lotus.jpg

Or even June-19-Lotus.jpg is fine. 


Thanks in advance.

Kiran

Hi @KiranGongani 

 

Please have a look at the flow below:qqas.png

Expression used in the file name is: 

concat(formatDateTime(utcNow(),'MMM-dd'),'-',items('Apply_to_each')?['DisplayName'])

Hope this Helps!

Hi @KiranGongani 

 

You must be referencing the wrong identifier in the delete attachment. You have to use the identifier of the get attachments' dynamic value instead of the add attachment ones. Can you please check and confirm this

@yashag2255  Thank you so much!!! This is the solution I was looking for! it worked as per my requirements. You Rock!!

 

Thanks,

Kiran

Hey @KiranGongani 

 

Glad that it worked!

 

Thanks, 

Yash. 

@yashag2255 One concern, when we add another/second attachment then it's deleting the old first one and retaining only the latest one. Any idea how to resolve this? it works only with one attachment.

@KiranGongani 

 

Can you share more details? I tied this with 2 attachments it was working. (the apply to each loop takes into account all the attachments). Can you share a screenshot of the flow so that I can have a better look at it?

Hi @yashag2255 It works when adding new/first time but does not work while modifing or adding addtional attachments. Screenshot for your refernece. AttachmentRenameFlow.pngThanks again for your help.  

HI @KiranGongani 

 

This is strange! I just tried adding 6 attachments and it worked just fine in my case. Can you share details on how you are attaching the attachments to the item? I also wanted to check if these attachments will be added in a single go (on a particular day) or on multiple days?

Hi @yashag2255 Thanks again for your reply. uploading attachment frequency is not determined, it's random. User may upload while creating the item and come back on same day and upload another attachment or may come back after two days and upload another attachment. So

 If the user uploads another attachment after couple of days, then the existing attachment will also get renamed once again (Is there way to check if it's already has date time stamp then skip). Please let me know if you need more info from my end. 

 

I am uploading attachments through normal process of uploading attachments for a sharepoint list item.

 

 

 

Hi @KiranGongani 

 

Instead of building a logic on checking if the attachment has a valid date as prefix, I have this dirty work around for you (But it works)

 

See the flow below and replicatefad1.png

 

fad2.png

 

In the array for months:

 

[
"Jan",
"Feb",
"Mar",
"Apr",
"May",
"Jun",
"Jul",
"Aug",
"Sep",
"Oct",
"Nov",
"Dec"
]

In the set variable action:

 

 

split(items('Apply_to_each')?['DisplayName'],'-')

In the condition on the right side:

 

first(variables('attch'))

What the flow does is, it will get the attachment and break the name over '-' (considering that the '-' might exist in a file name) we are checking if the prefix (the month is the first element of the attachment name as per our naming convention) exists in the other array that is an array of months and then perform respective actions. 

 

Hope this Helps!

Hi @yashag2255 Thanks for your help and appreciate the patience. I tried the new flow but it's not saving due to variable initailzation for attach variable, I tried giving possible intial values but still getting the following error. 


Error message:

"The inputs of workflow run action 'Condition' of type 'If' are not valid. The variable 'attch' must be initialized before it can be used inside action 'Condition'."AttachmentRenameFlow2.JPG

Hi @KiranGongani 

 

That is strange! Can you please put [] this in the Intiialise variable (attach) and try once? Also, can you please check the expression that you put there? 

 

This could also be a caching issue so you might want to save the flow and log out of the current session -> close the browser and start a fresh session. 

 

Please try the above and see if you contiue to get the error. 

 

 

Sorry @yashag2255  I tried the below steps but no luck. 

@KiranGongani 

 

Ah! I think I found the issue:

 

It should be the months array instead of the attach array that is on the left side in the condition and it should be first(attach) in the right side. 

 

Hope this Helps!

@KiranGongani 

 

and this expression 

first(variables('attch'))

should be 

first(variables('attach'))

as you have named your variable attach. 

Really sorry for that @yashag2255  : I did not realize that the variable name is used in the expression! Appreciate your patience. After updating the expression the workflow ran without any error but it's deleting the renamed file instead of the original file 😞

Hi @KiranGongani

@yashag2255 Thank you so much Yash!!! it's working as expected! I appreciate your patience and willingness to help!!! Also, apologize for not following exact instructions and because of that you had to spend extra time to resolve the same.

Thank you!Thank you!


Thanks again!

Glad that it worked! Happy Flowing!

Thank you for this post.  It helped me setup a flow to rename the attachments. As I was testing I ran into a use case that i would like to find a solution for.

 

The use case is this. Attach a file, let the flow run, then add a second attachment, let the flow run again.  What happens for me is the 1st attachment gets renamed a second time.  It isn't a big deal but it would be nice if the apply to each would be able to skip a file that already has prefix.

 

The only difference for me in my flow is I use the ID and a hyphen as the prefix. 

Here is a screenshot of 3 attachments. the first 2 were first added together and the 3rd on a second edit.

September User Group Success Story: Reading Dynamics 365 & Power Platform User Group

The Reading Dynamics 365 and Power Platform User Group is a community-driven initiative that started in September 2022. It has quickly earned recognition for its enthusiastic leadership and resilience in the face of challenges. With a focus on promoting learning and networking among professionals in the Dynamics 365 and Power Platform ecosystem, the group has grown steadily and gained a reputation for its commitment to its members!   The group, which had its inaugural event in January 2023 at the Microsoft UK Headquarters in Reading, has since organized three successful gatherings, including a recent social lunch. They maintain a regular schedule of four events per year, each attended by an average of 20-25 enthusiastic participants who enjoy engaging talks and, of course, pizza.   The Reading User Group's presence is primarily spread through LinkedIn and Meetup, with the support of the wider community. This thriving community is managed by a dedicated team consisting of Fraser Dear, Tim Leung, and Andrew Bibby, who serves as the main point of contact for the UK Dynamics 365 and Power Platform User Groups.   Andrew Bibby, an active figure in the Dynamics 365 and Power Platform community, nominated this group due to his admiration for the Reading UK User Group's efforts. He emphasized their remarkable enthusiasm and success in running the group, noting that they navigated challenges such as finding venues with resilience and smiles on their faces. Despite being a relatively new group with 20-30 members, they have managed to achieve high attendance at their meetings.   The group's journey began when Fraser Dear moved to the Reading area and realized the absence of a user group catering to professionals in the Dynamics 365 and Power Platform space. He reached out to Andrew, who provided valuable guidance and support, allowing the Reading User Group to officially join the UK Dynamics 365 and Power Platform User Groups community.   One of the group's notable achievements was overcoming the challenge of finding a suitable venue. Initially, their "home" was the Microsoft UK HQ in Reading. However, due to office closures, they had to seek a new location with limited time. Fortunately, a connection with Stephanie Stacey from Microsoft led them to Reading College and its Institute of Technology. The college generously offered them event space and support, forging a mutually beneficial partnership where the group promotes the Institute and encourages its members to support the next generation of IT professionals.   With the dedication of its leadership team, the Reading Dynamics 365 and Power Platform User Group is poised to continue growing and thriving! Their story exemplifies the power of community-driven initiatives and the positive impact they can have on professional development and networking in the tech industry. As they move forward with their upcoming events and collaborations with Reading College, the group is likely to remain a valuable resource for professionals in the Reading area and beyond.

September featured user group leader

 Ayonija Shatakshi, a seasoned senior consultant at Improving, Ohio, is a passionate advocate for M365, SharePoint, Power Platform, and Azure, recognizing how they synergize to deliver top-notch solutions. Recently, we asked Ayonija to share her journey as a user group leader, shedding light on her motivations and the benefits she's reaped from her community involvement.      Ayonija embarked on her role as a user group leader in December 2022, driven by a desire to explore how the community leveraged various Power Platform components. When she couldn't find a suitable local group, she decided to create one herself!    Speaking about the impact of the community on her professional and personal growth, Ayonija says, "It's fascinating to witness how everyone navigates the world of Power Platform, dealing with license constraints and keeping up with new features. There's so much to learn from their experiences.:        Her favorite aspect of being a user group leader is the opportunity to network and engage in face-to-face discussions with fellow enthusiasts, fostering deeper connections within the community. Offering advice to budding user group leaders, Ayonija emphasized the importance of communication and consistency, two pillars that sustain any successful community initiative.      When asked why she encourages others to become user group leaders, Ayonija said, "Being part of a user group is one of the best ways to connect with experienced professionals in the same field and glean knowledge from them. If there isn't a local group, consider starting one; you'll soon find like-minded individuals."      Her highlight from the past year as a user group leader was witnessing consistent growth within the group, a testament to the thriving community she has nurtured. Advocating for user group participation, Ayonija stated, "It's the fastest route to learning from the community, gaining insights, and staying updated on industry trends."   Check out her group: Cleveland Power Platform User Group
