Imapsync presentation by Gilles
Imapsync is an IMAP transfer tool. The purpose of imapsync is to migrate IMAP accounts or to backup IMAP accounts. IMAP, IMAP4 in fact (started December 1994), is one of the three current standard protocols used to access mailboxes, the two other being POP3 (started November 1988) and HTTP (started May 1996) with webmails, webmails are often tied to an IMAP server.
The latest imapsync published release 2.314 was written on Tuesday, 23-Sep-2025 16:55:45 UTC
Imapsync is a command-line tool that allows incremental and recursive IMAP transfers from one mailbox to another, both anywhere on the internet or in your local network. Imapsync runs on Windows, Linux, Mac OS X. "Incremental" means you can stop the transfer at any time and restart it later efficiently, without generating duplicates. "Recursive" means the complete folders hierarchy can be copied, all folders, all subfolders etc. "Command-line" means it's not a graphical tool, on Windows you have to run imapsync from a batch file. Anyway there is a visual online service, you can try imapsync online at https://imapsync.lamiral.info/X/
Imapsync can't migrate Contacts and Calendars. Most email systems don't set or get Contacts or Calendars via the IMAP protocol. No way via IMAP, no way via imapsync but it can be done with other tools or via export/import of csv or ics files. Also consider using caldavsynchronizer or asking experts at Sumatra company.
Imapsync is not suitable for maintaining a synchronization between two active imap accounts while the user is working on both sides. See why in the Two Ways Sync document. Use offlineimap (written by John Goerzen) or mbsync (written by Michael R. Elkins) for bidirectional (2 ways) synchronizations.
Imapsync can't backup nor restore email messages to or from a local directory. Imapsync works only with IMAP accounts, which always belong to some IMAP server. Read the Archiving document to get several solutions, at least four solutions, to this issue.
Alternatives to imapsync are listed in the Similar softwares section.
Alternatives to the imapsync online service are listed in the External online services section.
Good feedback is always welcome!
and bad feedback is very often welcome
It may sounds crazy but I do reply personally to every single email message I receive, so don't hesitate to spend time writing to me about your email problems, you're sure to get my attention and my time.
Imapsync was the best investment I've ever done.

Read some other nice and true testimonials from users.
There is no trial version but I offer 30-day money back guarantee whatever the
reason for a refund. Or drop me a gentle email and I will provide you the latest imapsync because,
well, you made the effort to contact me.
After downloading imapsync, go to the installation documentation.
Special offer: it's only €144 EUR if you buy imapsync + support at once (instead of 72 + 144 = 216 EUR).
For €144 EUR you will get:
For €72 EUR you will get all the above except imapsync full professional support (the first line).
For €144 EUR independently, you get imapsync full professional support, provided by the imapsync designer and developer, Gilles LAMIRAL, your servitor, who has been supporting imap migrations with imapsync for more than 20 years (I started in 2001). See a detailed support description below.
You may wonder why the support alone is the same price as imapsync+support? It's because when you buy both at once, I'm not sure I will have to spend some time directly with you, it's possible that everything goes smoothly for you, since this aim is my daily work. But when you buy the support alone, after buying the software, then I will surely spend time (any amount of hours) to help you. Does it seem fair enough?
Instantly at the end of the payment, Paypal will proposed you to go back to the site,
via a link to gilles@lamiral.info (it's my paypal account name),
this link brings you to imapsync download.
You will also receive an email from gilles@lamiral.info a few minutes later
(it can fall in the Spam folder sometimes).
In order to get an accurate invoice, please make sure the delivery postal address you enter in Paypal
suits your accounting department, since revised editing is not easy.
Your invoice will be sent within a few days by email.
My company is identified by VAT number FR74429303332 or French SIRET number 42930333200051,
French APE/NAF number 6201Z ("programmation informatique" in French, aka, computer programming).
For those of you who seek support, contact me, Gilles LAMIRAL, by email or phone:
The support is done in English, mostly by email or possibly phone/skype. Office hours start at 10:00, end at 16:00 UTC, extra time is possible in case of emergency. The support aims at helping you to get your imap migration job done, quickly if possible. Support includes things like no time to read the documentation, how to deal with special imap software servers (Gmail, Office365, Exchange etc.), choosing and explaining options, explaining error messages, solving authentication issues, dealing with speed, quotas, special context, running in parallel, etc., so in summary: anything! except doing the job for you.
I have been supporting imap migrations with imapsync since 2001, I still enjoy it!
If you can't pay with a credit card via Paypal then it is possible to pay via a bank transfer.
Refund for a bank transfer is less easier than with Paypal so drop me an email to test imapsync
and to be sure it will do what you need it to do, before any payment.
The bank account references will be given upon request.
It will surely add extra work editing manually the invoice, back and forth getting good coordinates, so I will charge both software and support normal prices for a payment via bank transfer, that is 144 EUR.
The funny thing about crypto payments is that I receive very few of them, one or two per year, and in small amount, usually one or two dollars equivalent. Maybe one day those little crypto coins will be like gold, I will love that!

The figures presented here do not include the GitHub imapsync release usage. It's because --noreleasecheck is on by default in the GitHub release, since release 1.592 (2014/05/22). Looking at the numbers before and after 2014, the figures showed above could be doubled.
Where all those numbers come from? To know whether a newer imapsync exists or not, imapsync does an http GET to the file VERSION. Via the User-agent parameter it also sends:
You can remove this behavior by adding the option --noreleasecheck on the command line (or by setting $releasecheck = 0 in the source code). Check CVE-2013-4279.
After Imapsync installation, you have to edit a "ready to use" batch file called imapsync_example.bat and run it by a double-click. This batch file is also in the zip archive so it's useless to download it.
I strongly advise you to read and follow the document README_Windows.txt
After Imapsync installation, you have to edit a "ready to use" script file called imapsync_example_darwin.bat and run it in a shell window. This script file is also in the tgz archive so it's useless to download it.
I strongly advise you to read first and follow the document INSTALL.Darwin.txt and then the document TUTORIAL_Unix.
Here after is presented a Linux imapsync command line example. You can try it on a terminal, as is. Anyway, it's easier to edit a shell script with the same exact command and run this script in a terminal or from a graphical desktop. Just take the Bourne shell script example imapsync_example.sh and adapt with your own parameters. This shell script file is also in the tgz archive so it can be useless to download it.
I strongly advise you to read and follow the document TUTORIAL_Unix.
After Imapsync installation, a basic example in a shell terminal is the following:
./imapsync \ --host1 test1.lamiral.info \ --user1 test1 \ --password1 "secret1" \ --host2 test2.lamiral.info \ --user2 test2 \ --password2 "secret2"
In order to migrate many mailboxes, you should use a loop over a csv
file containing only the data credentials.
On Windows, see sync_loop_windows.bat
batch example.
On Unix, see sync_loop_unix.sh
example.
An example of this csv file is file.txt,
it can be used with the two previous command scripts.
All example scripts can be found in the examples/* directory.
I strongly advise you to read also the following FAQ documents:
Hardware system requirements:
Operating System requirements: Imapsync is avalable on Windows, Mac and Linux.
Which Operating System to chose?
Use the Operating System you are the most familiar with.
Location requirements:
Where to place imapsync?
Any host in any place is ok for imapsync as long as it
has a network access to both IMAP servers, the source and the destination.
What to do next?
Depending on the system where you will run imapsync:
After the imapsync installation you should go to the documentation section just below.
Windows users, the README_Windows.txt contains essential knowledge to do your first syncs.
Unix users, the TUTORIAL_Unix will teach you smoothly how to do your first syncs. Windows users can read it too.
The README file contains general and specific pieces of information to understand imapsync and succeed in your migration or backup.
The FAQ.d/* files present Frequently Asked Questions (and not so frequently asked ones) and their answers. Here is the main menu, take at least the time to read the menu, you will certainly lose some time to read it, two minutes, but reading this menu will most likely save you some struggling hours later, believe me. So read the three columns main menu:
In 2024, buying a used physical copy of a PS3 game often costs $5 to $10. Meanwhile, downloading a "highly compressed" ISO might take 8 hours, fill your hard drive with fragmented temp files, and expose your IP address to legal notices.
Yet, the demand persists. For every gamer in a developing nation where a PS3 disc costs a month's salary, or for the preservationist archiving the Tokyo Jungle beta, the hunt for the high-quality, highly compressed ISO remains the final frontier of the PS3 era.
Just remember: If a website promises you The Last of Us in 500MB with "Ultra HD graphics," it isn't compression. It's a lie.
Stay safe, keep your antivirus on, and emulate responsibly.

Recommendations
Downloading PS3 game ISOs is a popular way to preserve and play classic titles, especially as physical discs become rarer. To run these files on a console, you generally need a jailbroken PS3 using Custom Firmware (CFW) or PS3HEN. Popular Highly Compressed & High-Quality Games
Many high-quality PS3 titles are available in "highly compressed" formats or naturally small file sizes that don't compromise graphics. Uncharted 2: Among Thieves
The world of PlayStation 3 game downloads focuses heavily on three formats: ISOs, Game Folders, and PKGs. For most users, High-Quality ISOs are the preferred choice due to their speed, compatibility, and ease of management. Why Choose PS3 ISO Format?
An ISO is a complete disc image of a game. While "highly compressed" usually refers to the file being packed into a .zip or .7z archive for download, the format itself offers several technical advantages once extracted:
Faster Transfer Speeds: ISOs are single large files. Transferring one 10GB ISO to your PS3 is significantly faster than transferring a "Game Folder" (JB Folder) that might contain 20,000 tiny individual files.
External Drive Compatibility: ISOs can be played directly from NTFS-formatted external hard drives, allowing you to bypass the 4GB file size limit of the standard FAT32 format.
Better Compatibility: Some games that fail to run in folder format work perfectly as ISOs. Ps3 Games Download High Quality Iso Highly Compressed
Emulator Optimization: For those using the RPCS3 emulator on PC, the PS3 Disc Image (ISO) is the most common and recommended format. Popular High-Quality PS3 Titles

The Ultimate Guide to PS3 Games: High-Quality ISOs and Highly Compressed Downloads
The PlayStation 3 era remains one of the most beloved chapters in gaming history, featuring legendary titles that pushed hardware boundaries. Today, many fans look to preserve these experiences through high-quality ISO files, whether for use on original hardware or advanced emulators like RPCS3.
This guide explores how to find, manage, and optimize your PS3 game library, focusing on quality, compression, and safe handling. Understanding PS3 Game Formats: ISO vs. PKG vs. Folder
Before downloading, it is essential to understand the different ways PS3 games are packaged:
ISO (Disc Image): The most recommended format for RPCS3 and general preservation. It is a 1:1 copy of the game disc, ensuring high quality and compatibility.
Folder (JB Format): Games extracted into a directory structure. While common, these often need to be converted to ISO using tools like PS3 ISO Tools for better performance on modded consoles.
PKG (Package): These are digital-style installers used for PlayStation Network (PSN) titles or updates. They are installed directly through the PS3’s XMB menu. Top PS3 Games for High-Quality Emulation
If you are looking for visual showcases to test your setup, these titles are widely considered the gold standard for PS3 graphics and production:
.7z file up to 50–70% smaller than original ISO.Note: Extracting will take time and CPU power. The gain is smaller file size for storage.
Before diving into the how, let's look at the why. Highly compressed PS3 games are not just smaller files; they represent a technical solution to a storage crisis.
If you downloaded a raw ISO from a Blu-ray rip, you need a decryption key. Most trusted sites provide decrypted ISOs already. If not, use PS3 Decrypt Tool or 3k3y ISO Tool.
To search for the right files, you need to understand what you are downloading:
