Solutions for Inability to Upload Files on Allganize
When unable to upload files on Allganize (Alli), the first things to check are the file format, file size, and upload target functionality.
On Allganize, the allowed file formats and conditions vary depending on the use case, such as document registration and Q&A data import. Therefore, even if the file itself has no issues, an error can occur if the target functionality does not support it.
First, check the following items in order.
- Is the upload target appropriate, such as "Document," "Q&A," or "Chat"?
- Does the file extension match the supported formats for that functionality?
- Is the file size within the allowed limit?
- For multiple files or ZIP files, does it comply with the restrictions for bulk uploads?
- Is it the case that while the file upload is completed, the parsing process has not yet finished?
It is particularly important to note that the supported conditions vary depending on the upload destination. Below, we will explain specific checking methods and solutions.
1. Check if the File Format is Supported
One reason for being unable to upload files on Allganize is selecting a file format that is not supported.
For instance, for the knowledge base document functionality, the official guide lists formats such as txt, docx, csv, xls, xlsx, xlsm, jpg, jpeg, png, hwp, hwpx, zip, pdf, ppt, pptx, and doc.
On the other hand, for bulk uploads in Q&A, formats like TSV, CSV, XLSX, and ZIP are used. When attaching files in the chat screen, the supported formats can differ based on the app or settings, so you cannot directly apply the document functionality’s supported formats.
Start by checking the official guide for the functionality you are using.

Points to Note When Checking File Extensions
The strings at the end of the file name, such as ".pdf," ".xlsx," or ".docx," are the file extensions. Check to see if it is a supported format.
However, merely changing the file name's extension does not alter its internal format. For example, changing a JPEG image's extension to PDF does not make it a valid PDF file.
If another format is needed, it is typically best to convert it to a supported format using the original application before uploading.
2. Check if the File Size Exceeds the Limit
Even if there are no issues with the file format, exceeding size limits can result in upload failures.
On Allganize, size limits differ based on the functionality being used. For example, the official guide states that when uploading documents as a ZIP file, the total size limit for the ZIP file is 1GB. Additionally, in some chat input functionalities of Alli Works, the total size for attached files is capped at 100MB.
These are different functionality constraints and not a universal limit across Allganize. Check the actual upload screen and the official guide corresponding to the functionality you are using to confirm the limits.
Solutions When the Size is Too Large
- Remove unnecessary pages or data to reduce the file size.
- Adjust the resolution or quality of images.
- If multiple files are bundled, split them as needed.
- If it is a ZIP file, review the compression target and folder structure.
However, compressing into a ZIP file does not always result in a significantly smaller size due to the original data. Therefore, it is not guaranteed that the file will fit within the limits simply by compressing; be sure to check the size of the final file.
3. Check the Structure of ZIP Files or Multiple Files
If you are attempting to register multiple documents at once, be careful about the structure of the ZIP file.
In Alli’s document functionality, you can use a ZIP file to upload multiple documents following the internal folder structure. However, being able to upload does not guarantee that all files will be parsed correctly.
If the upload fails, check the following points.
- Can the ZIP file be opened normally?
- Are the necessary files included in the ZIP file?
- Is the structure of folders and files as intended?
- Are the target documents in a supported format?
- Is the total size of the ZIP file within the limits?
Moreover, if you are including images or attachments in bulk registration for Q&A, be cautious about the placement of data files such as CSV or XLSX and how attachment files are named. The steps for normal document bulk registration and Q&A bulk registration differ, so refer to the guide that suits your purpose.

4. Check if the Parsing Process After Upload is Complete
Even if the file upload appears to be complete, it does not necessarily mean it is immediately usable.
In Alli's document functionality, parsing occurs after the upload of documents. Therefore, even if the file is registered, if parsing is still in progress, search and response utilization may not yet be possible.
In this case, it is important to check distinctly from simple upload failures.
- Is the target file registered in the document list?
- Has the parsing status for the file been completed?
- Are there no error messages or indications of ongoing processing?
- Have you refreshed the list as needed to check the latest status?
If registration is complete, check the parsing status before re-uploading the same file multiple times. If the parsing takes an unusually long time or an error is displayed, consider contacting the administrator or Allganize's support desk.
5. If Only Specific Files Cannot Be Uploaded
If other files can be uploaded normally, but specific files fail, there may be issues specific to those files.
File Is Corrupted
If the original file is corrupted or if the save operation was not completed successfully, it may fail during upload or parsing. Open the file in the original application to verify if it can be read correctly.
Problems with Content or Structure of the File
For data files like Excel or CSV, the structure of columns or data encoding may not match the expected format for the registration functionality.
Especially for bulk uploads in Q&A, verify that the necessary rows, such as questions and answers, are correctly prepared. Even if the file has a supported extension, if the content varies from the required format, registration may still fail.
Problems with Naming or Designation of Attachment Files
When including images or attachment files in Q&A, the official guide indicates that using Japanese characters in filenames or ZIP file names may not be permitted.
If your case falls under such functional constraints, change the filenames to alphanumeric characters and attempt uploading again in the specified format.
6. There May Be Issues on the Allganize Side
If there are no problems with file format or size and similar errors occur across multiple files, it might indicate a service-related issue or a temporary malfunction.
Alli's official maintenance and outage information has recorded instances where document uploads or parsing became unstable in the past. For example, on January 27, 2026, instability in uploads and parsing was reported, and it was indicated that it was restored within the same day.
As such, cases may arise where changing files on the user side does not resolve the issue, so if similar symptoms persist, check the official outage information.
Reference: Alli LLM App Market Maintenance and Fault Information
Even if no pertinent content is found in the outage information, if errors repeatedly occur, organize details such as the time of occurrence, error messages, the format and size of the problematic file, and the functionality used for inquiries to help identify the cause.
7. If You Want to Share Files with Another Party, UploadF is Also Convenient
If you've tried all the methods introduced so far but still cannot resolve the issue, or if your goal isn’t to register files on Allganize but to simply pass files to someone else, consider using another file-sharing service.
For example, UploadF (uploadf.com) is a free file uploader that can be used without account registration. It is compatible with both computers and smartphones, allowing you to obtain a shareable URL after uploading files.
- Free to Use: Files can be shared without membership registration or personal information entry.
- Multiple Files Supported: You can upload up to 100 files at once.
- Wide Range of Supported File Formats: It supports around 150 types of extensions, including documents, images, audio, video, and compressed files.
- Set Retention Period: You can specify and extend the file retention period.
- Password Protection: You can set a password for shared files.
- Individual Deletion: There is a function to individually delete uploaded files.
You can simply upload a file and communicate its shareable URL, making it useful for files that are difficult to attach to emails or for passing multiple materials together.
Please note that UploadF is a service for sharing files and does not perform document registration or AI parsing for Allganize. If you need registration on Allganize, the conditions regarding file formats and sizes must still be met.
If your goal is to pass files to someone, try UploadF.
Conclusion: Take Action According to the Cause
If you cannot upload files on Allganize, first check the target functionality, supported file formats, size restrictions, ZIP file structure, and parsing status in order.
If only specific files fail, it may be an issue with the files themselves, while failures across multiple files may indicate an issue on the service side. If separating the causes does not resolve the situation, checking the official outage information or support channels is recommended.
Furthermore, if there is no need to register files with AI and the goal is simply to share them with another person, a free file uploader like UploadF is also an option. Choose the method that best suits your purpose and smoothly share your files.
