+## Get file information
+We have two endpoints `fileinfo` and `filesinfo` from which we can get the information of a single or multiple files.
+
+### Requirements
+This endpoint has a soft dependency on Nextcloud's [Activity](https://github.com/nextcloud/activity) app. In the absence of the Activity app the response fields like `modifier_name` , `modifier_id` will be returned as null. So, it is encouraged to have Activity app installed and enabled.
+
+1. **Get information of single file**: 
+Send the `GET` request to `fileinfo` endpoint with `FILE_ID` of the file to retrieve information.
+
+	```bash
+	curl -H "Accept: application/json" -H "OCS-APIRequest: true" -u USER:PASSWD http://<nextcloud_host>/ocs/v1.php/apps/integration_openproject/fileinfo/<FILE_ID>
+	
+	```
+	Upon success the response from the above curl request will be
+	```json
+	{
+	  "ocs": {
+		"meta": {
+		  "status": "ok",
+		  "statuscode": 100,
+		  "message": "OK",
+		  "totalitems": <totalitems>,
+		  "itemsperpage": <itemsperpage>
+		},
+		"data": {
+		  "status": "OK",
+		  "statuscode": 200,
+		  "id": <FILE_ID>,
+		  "name": <file_name>,
+		  "mtime": <mtime>,
+		  "ctime": <ctime>,
+		  "mimetype": <mimetype>,
+		  "size": <size>,
+		  "owner_name": <owner_name>,
+		  "owner_id": <owner_id>,
+		  "trashed": <boolean>,
+		  "modifier_name": <modifier_name>,
+		  "modifier_id": <modifier_id>,
+		  "dav_permissions": <dav_permissions>,
+		  "path": <path>
+		}
+	  }
+	}
+	```
+2. **Get information of multiple files**:
+Send the `POST` request to `filesinfo` endpoint with data `fileIds` of the files to retrieve information.
+
+    ```bash
+    curl -H "Accept: application/json" -H "Content-Type:application/json" -H "OCS-APIRequest: true" -u USER:PASSWD http://<nextcloud_host>/ocs/v1.php/apps/integration_openproject/filesinfo -X POST -d '{"fileIds":[<FILE_ID1>, <FILE_ID2> ,...]}'
+	
+    ```
+    Upon success the response from the above curl request will be
+    ```json
+    {
+        "ocs": {
+            "meta": {
+                "status": "ok",
+                "statuscode": 100,
+                "message": "OK",
+                "totalitems": <totalitems>,
+                "itemsperpage": <itemsperpage>
+            },
+            "data": {
+                <FILE_ID1>: {
+                    "status": "OK",
+                    "statuscode": 200,
+                    "id": <FILE_ID1>,

+                <FILE_ID2>: {
+                    "status": "OK",
+                    "statuscode": 200,
+                    "id": <FILE_ID1>,

+        }
+    }

 ## Direct upload
 There's an end-point `direct-upload` available which can be used for direct-upload. There's two steps to direct upload. First we need to get the `token`. Then use the token in the direct upload request.
