Move before you delete, do one share at a time, and tell people before folders change, because mapped drives, shortcuts and linked spreadsheets point at paths. A shared NAS gets messy in a particular way. Unlike a personal Google Drive, everyone in the office has been filing into it for years, each with their own idea of where things go, and nobody owns the whole thing. The result is three folders called `Clients`, a `Scans` share that only grows, and an `Old server` folder that someone copied across in 2019 and nobody has opened since. These steps work on any NAS (Synology, QNAP, TrueNAS) and on a Windows file server. Where an AI assistant saves time, it's noted, but every step can be done by hand. ## 1. Why take a snapshot before you start? Because a cleanup is a lot of moves, and moves are where files go missing. A snapshot is a read-only copy of the share as it is today, and it's the fastest way back from any mistake. - On a **Synology**, use Snapshot Replication on the share (it needs a Btrfs volume), or check your Hyper Backup task ran last night. - On a **QNAP**, take a snapshot in Storage & Snapshots. - **Turn on the recycle bin** for every share you'll clean: `#recycle` on Synology, `@Recycle` on QNAP. Then anything deleted by hand or by a tool can be recovered for the retention period. ## 2. What's actually on the NAS? Find out before you plan anything. You want four numbers per share: total size, number of files, the date of the newest file, and the biggest folders. By hand, Synology's [Storage Analyzer](https://www.synology.com/en-us/dsm/7.4/software_spec/storage_analyzer) produces reports of shared folder sizes, the largest files, the most recently modified files and the least recently accessed ones, and exports them as CSV. On a QNAP, a folder's properties in File Station give its size and file count. With an AI assistant connected to the NAS, you can just ask: ``` Give me a summary of the Clients share: size per top folder, how many files, and the newest file in each. ``` ``` Which folders on the NAS haven't had a new file since 2022? ``` The answer usually changes the plan. Most offices find that a handful of folders hold most of the space, and that a large part of the NAS hasn't been touched in years. ## 3. What folder structure should an office NAS use? One that a new hire could guess. For most small offices, that means a few top-level shares by function, then one level by client or project, then one level by year or type: ``` Clients/ Acme Corp/ 2025/ 2026/ Brightwater LLC/ Admin/ HR/ Finance/ Templates/ Archive/ Scans/ ← the inbox, emptied regularly ``` Three rules make it hold up: - **Keep it shallow.** Three or four levels deep at most. Deep trees are where files get lost, and long paths break on Windows. - **Put permissions at the top.** HR and Finance are separate shares, or separate top folders with their own permissions, not subfolders of a share everyone can read. See [file permissions for teams](https://thedrive.ai/blog/file-permissions-access-control-for-teams). - **Agree it before you move anything.** Write it down in a `README` at the top of the share, and get the two or three people who file the most to say yes. ## 4. What naming rule should everyone follow? Pick one pattern and use it for everything new: ``` 2026-03-14 Acme Corp - Engagement letter (signed).pdf ``` Date first in `YYYY-MM-DD` so files sort by date, then the client, then what the document is. Avoid characters that break on one platform or another (`/ \ : * ? " < > |`). Our guide to [creating a file naming convention](https://thedrive.ai/blog/how-to-create-file-naming-convention) covers the details. Renaming the old files is the step that's impossible by hand at any scale. Nobody is going to open 6,000 scans named `scan_0412.pdf` to see what each one is. This is where AI earns its keep: an assistant that reads each file can propose a name for every one of them, and you review the list before anything changes. ``` Rename every scan in /Scans/2025 using the format: date, client, document type. ``` ## 5. How do you deal with duplicates on a NAS? Move them, don't delete them. Create a `_Duplicates to review` folder, move the extra copies there, and leave it for a month. If nobody asks for anything, empty it. Finding them is the hard part. Synology's Storage Analyzer has a duplicate files report, which matches files on attributes such as name, size and modified date and lists up to 5,000 of them. That catches copies saved under the same name. It misses the same contract saved as `Acme MSA final.pdf` in one folder and `Contract v3.pdf` in another. An AI assistant that has read the documents can group those too, because it compares what the files say rather than what they're called. Scans without a text layer are compared once they've been read. Decide which copy to keep before you start. Usually it's the one in the folder that matches your new structure, and failing that, the oldest. Our post on [finding duplicate files](https://thedrive.ai/blog/find-duplicate-files-google-drive) goes into choosing the copy to keep, and the same rules apply on a NAS. A practical warning: an identical copy of a file isn't always a mistake. A contract may sit in both the client's folder and a `Signed 2025` folder because two people use it differently. Ask before you remove the "duplicate" someone relies on. ## 6. What should you do with old files? Archive them; don't delete them. Move folders that haven't changed in a few years into an `Archive` share with read-only permissions for most people. They stay searchable and recoverable, but they stop cluttering the folders people use every day. Before deleting anything for good, check whether you're required to keep it. Tax, employment and client records have minimum retention periods that vary by country and industry, and anything under a legal hold must not be touched. [Records retention schedules](https://thedrive.ai/blog/records-retention-schedule-compliance) explains how to set the periods. ## 7. How do you keep the NAS clean afterwards? A cleanup lasts about six months unless something enforces it. Three things help: - **An inbox.** New scans and downloads land in one place (`Scans`), not wherever someone happened to save them. - **One owner.** Someone looks at the inbox weekly, or a rule does. - **An automatic rule for the inbox.** With an assistant watching the share, a sentence becomes a workflow: ``` From now on, when a new file lands in /Scans, rename it to the date, client and document type, and move it to that client's folder. ``` Because a NAS is always on, a workflow like this runs as files arrive. ## How do you avoid breaking things when files move? Paths are what break. Before the big moves, tell people what's changing and when, then check these: - **Mapped drives and shortcuts** on people's computers that point into folders you're renaming. - **Linked spreadsheets.** An Excel file that pulls figures from another workbook stores that workbook's path, and the link breaks if either file moves. - **Software that saves to a fixed folder**, such as a scanner's scan-to-folder destination, an accounting package's export path or a backup job's source. - **Bookmarks in File Station** and saved links in email. Do one share at a time, ideally on a Friday afternoon, so problems surface on Monday when you're expecting them. ## Can AI clean up a NAS for you? It can do the slow parts: working out what thousands of files are, renaming them, sorting them into the agreed structure, and finding folders nobody uses. It shouldn't decide your structure or your retention rules; those are yours to set. The Drive AI does this through a small Docker container on the NAS. The files stay on the NAS, every change is shown as one plan before anything moves, moves and renames undo as one change, and deletions go to the share's recycle bin. You can keep it out of sensitive shares, or let it see only names and dates there. [How to organize a Synology NAS with AI](https://thedrive.ai/blog/how-to-organize-synology-nas-with-ai) covers the setup. ## Frequently Asked Questions ### How do I organize a shared drive on a NAS? Take a snapshot first, then map what's there, agree a shallow top-level structure by function and client, agree a naming rule, move duplicates to a review folder, archive old folders, and set up an inbox with a rule that files new documents. Do one share at a time. ### Should I delete old files from the NAS? Archive them first. Move folders untouched for years to a read-only Archive share, and only delete after checking your retention obligations for tax, HR and client records. Anything under a legal hold must be kept. ### How do I find duplicate files on a Synology NAS? Run a duplicate files report in Storage Analyzer. It matches on attributes such as name, size and modified date and lists up to 5,000 duplicates, exportable as CSV. It won't find the same document saved under two different names; an AI assistant that reads the files can. Move duplicates to a review folder rather than deleting them. ### How deep should a folder structure be? Three or four levels at most. Deep trees hide files and produce paths too long for some Windows programs. Top-level shares by function, one level by client or project, and one by year usually cover a small office. ### How do I rename thousands of files on a NAS? Bulk renamers can apply a pattern to names you already have, but they can't tell what a file named `scan_0412.pdf` is. An AI assistant that reads each file can propose names from the contents. Review the proposed list before applying it, and keep a snapshot. ### Will moving files on the NAS break links? It can. Mapped drives, shortcuts, linked spreadsheets and software with fixed save folders all store paths. Tell people before moving folders, update fixed paths in scanners and software, and move one share at a time.
